More and more plainly, OpenAI and Anthropic are making plays to own (and lease) the "means of production" in software. OK - I'm a pretty happy renter right now.
As they gobble up previously open software stacks, how viable is it that these stacks remain open? It seems perfectly sensible to me that these providers and their users alike have an interest in further centralizing the dev lifecycle - eg, if Claude-Code or Codex are interfaces to cloud devenvs, then the models can get faster feedback cycles against build / test / etc tooling.
But when the tooling authors are employees of one provider or another, you can bet that those providers will be at least a few versions ahead of the public releases of those build tools, and will enjoy local economies of scale in their pipelines that may not be public at all.

I was using poetry pretty happily before uv came along. I’d probably go back.

The “requests” package gets downloaded one billion times every month, should that be a multi billion dollar VC company as well? It’s a package manager and other neat tooling, it’s great but it’s hardly the essence of what makes Python awesome, it’s one of the many things that makes this ecosystem flourish.

I use uv here and there but have a bunch of projects using regular pip with pip-tools to do a requirements.in -> requirements.txt as a lockfile workflow that I've never seen enough value in converting over. uv is clearly much faster but that's a pretty minor consideration unless I were for some reason changing project dependencies all day long.
Perhaps it never grabbed me as much because I've been running basically everything in Docker for years now, which takes care of Python versioning issues and caches the dependency install steps, so they only take a long time if they've changed. I also like containers for all of the other project setup and environment scaffolding stuff they roll up, e.g. having a consistently working GDAL environment available instantly for a project I haven't worked on in a long time.

I think the issue is that LLMs are a cash problem as much as they are a technical problem. Consumer hardware architectures are still pretty unfriendly to running models which are actually competitive to useful models so if you want to even do inference on a model that's going to reliably give you decent results you're basically in enterprise territory. Unless you want to do it really slowly.

What strikes me most about this acquisition isn't the AI angle. It's the question of why so many open source tools get built by startup teams in the first place.
I maintain an open source project funded by the Sovereign Tech Fund. Getting there wasn't easy: the application process is long, the amounts are modest compared to a VC round, and you have to build community trust before any of that becomes possible. But the result is a project that isn't on anyone's exit timeline.
I'm not saying the startup path is without its own difficulties. But structurally, it offloads the costs onto the community that eventually comes to depend on you. By the time those costs come due, the founders have either cashed out or the company is circling the drain, and the users are left holding the bag. What's happening to Astral fits that pattern almost too neatly.
The healthier model, I think, is to build community first and then seek public or nonprofit funding: NLnet, STF, or similar. It's slower and harder, but it doesn't have a built-in betrayal baked into the structure.
Part of what makes this difficult is that public funding for open source infrastructure is still very uneven geographically. I'm based in Korea, and there's essentially nothing here comparable to what European developers can access. I had no choice but to turn to European funds, because there was simply no domestic equivalent. That's a structural problem worth taking seriously. The more countries that leave this entirely to the private sector, the more we end up watching exactly this kind of thing play out.

Having a private package index gives you a central place where all employees can install from, without having to screen what each person is installing.

Projects like the Linux Foundation exist, too. And government funding, especially for scientific endeavors or where software is used to fulfill critical state tasks, is an option, too. I refuse to subject to the hypercommercialization of software and still believe in the principles behind open source.

Maybe you use non-transitive pure Python dependencies, but it's likely that your tools and dependencies still rely on stuff in Rust or C (e.g.: py-cryptography and Python itself respectively).

I use mostly the batteries, given that the only purpose I have for Python, since version 1.6, is UNIX scripting tasks, beyond shell.
As mentioned multiple times, since my experience with Tcl and continuously rewriting stuff in C, I tend to avoid languages that don't come with JIT, or AOT, in the reference tooling.
I tend to work with Java, .NET, node, C++, for application code.
Naturally AI now changes that, still I tend to focus on approaches that are more classical Python with pip, venv, stuff written in C or C++ that is around for years.

At worst, it's just Anaconda II AI Boogaloo. The ecosystems will evolve and overcome, or will die and different ecosystems rise to meet the need going forward.
I anticipate OpenAI will get bored and ignore Astral's tools. Software entropy will do its thing and we will remember an actively developed uv as the good old days until something similar to cargo gets adopted as part of Python's standard distribution.

The issue is lack of money not lack of legal structure.
How much money do they make from donations? I don't know but "In practice we frequently payed for travel and hardware."
Translation: nothing at all.
If such a fundamental project that is a revenue driver for so many companies, including midas-level rich companies like Google, can't even pay decent salaries for core devs from donations, then open source model doesn't work in terms of funding the work even at the smallest possible levels of "pay a reasonable market rate for devs".
You either get people who just work for free or businesses built around free work by providing something in addition to free software (which is hard to pull off, as we've seen with Bun and Astral and Deno and Node).
mcdonje 10 minutes ago [-]
Google contributed tons of developer hours for things like bug fixes, without which the project might not be where it is today.
There are examples of foundations or other similar entities paying developers, like Linux, SQLite, even Zig.
Maybe the difference is some projects rely on core contributors more because external contributions are more restricted in some way.
But sure, the entire open source model doesn't work, lol

Can't blame you for not trusting OpenAI, but it seems to me they would gain very little from fucking up uv (or more precisely doing things that have a side effect of fucking up uv), and they have tons of incentive to cultivate developer good will. Better to think of buying and supporting a project like this as a very cheap way to make developers think they're not so bad.

No they don't have incentive to cultivate developer goodwill. They are monetizing replacing developers everywhere. That is the trillion-dollar valuation. They have the opposite incentive.

They are not. A very large proportion of their revenue comes from developers. A large proportion of their marketing and product work is aimed at developers. You have to work really hard to not see this. Just look at what Altman and Brockman tweet about.

Curious how well upstream contributors or projects get contributed for these sort of headline-gathering acquisitions (probably not at all, unfortunately).
OpenClaw notably was built around Mario Zechner's pi[0]; uv I believe was highly adapted from Armin Ronacher's rye[1], and uses indygreg's python-build-standalone[2] for distributing Python builds (both of which were eventually transferred to Astral).
In the worst case, Astral will stop developing their tools, someone else will pick them up and will continue polishing them. In the best case, they will just continue as they did until now, and nothing will really change on that front.
Astral is doing good work, but their greatest benefit for the ecosystem so far was showing what's possible and how it's down. Now everyone can take up the quest from here and continue. So any possible harm from here out will be not that deep, at worst we will be missing out on many more cool things they could have built.

I know you can make them go away, but if you bounce between different systems, and particularly deal with installing VS Code on a regular basis, it becomes annoying.
I started using VS Codium, and it feels like using VS Code before the AI hype era. I wonder if we're going to see a commercial version of uv bloated with the things OpenAI wants us all to use, and a community version that's more like the uv we're using right now.

MS is actively making your life using VS Codium a pain.

That does not change with this acquisition. No one can guarantee how motives, incentives, and decisions might change years down the line. But that's why we bake optionality into it with the tools being permissively licensed. That makes the worst-case scenarios have the shape of "fork and move on", and not "software disappears forever".

While I -- like most other commenters -- am dubious of both OpenAI and this acquisition, I think it's pretty reasonable to wait to see how this turns out before rushing to final judgment.
Everything I've seen from Astral and Charlie indicates they're brilliant, caring, and overall reasonable folks. I think it's unfair to jump to call them sell-outs and cast uv and the rest as doomed projects.
krick 41 minutes ago [-]
Sure, I don't think anybody disagrees, I sure don't. You never know, and all. It's just that we (the imaginary crowd you are arguing with) are not hopeful. And your "but wait, guys, I think they are good people!" is some quite pitiful attempt to console us. Sure, good, brilliant and caring, that's why we are upset in the first place. Always more sad when it's somebody you liked that dies.
And framing it as "sell-outs" is cheap rhetoric that means nothing. The fact is, they were the company who never really had a solid business model, but provide a lot of value for the community. Being acquired by some infinite-money company was always the best outcome they could hope for. Well, they did. Probably got a ton of money. Will it require some sacrifice? Well, some people would say that working for a company who makes products for the Department of War of the USA on conditions that even Anthropic found too ugly to satisfy, is enough of a sacrifice on its own. I am pretty sure though that most people would be willing to make this sacrifice for the right amount of money (with "right amount" being a variable part). So calling someone a sell-out is usually just bitterness about the fact that it wasn't you who managed to sell out. I mean, not judging someone for a sacrifice they make isn't the same thing as pretending they didn't make a sacrifice. Sometimes we (the world, they were trying to make better) are a sacrifice. That's all.

i feel like moves like this make it even harder for new open-source tools to break through. there's already evidence that LLMs are biased toward established tools in their training data (you can check it here https://amplifying.ai/research/claude-code-picks). when a dominant player acquires the most popular toolchain in an ecosystem, that bias only deepens. not because of any skewing, but because the acquired tools get more usage, more documentation, more community content. getting a new project into model weights at meaningful scale is already really hard. acquisitions like this make it even harder.
fortuitous-frog 2 hours ago [-]
I'm also concerned about this, but I feel as though uv and ruff's explosive growth happening alongside and despite that of LLMs demonstrates that it's not a show-stopper. I vividly recall LLM coding agents defaulting to pip/poetry and black/flake8, etc. for new projects. It still does that to some extent, but I see them using uv and ruff by default -- without any steering from me -- with far greater frequency.
Perhaps it's naive optimism, but I generally have hope that new and improved tools will continue to gain adoption and shine through in the training data, especially as post-training and continual learning improve.

The Bun acquisition made a little sense, Boris wanted Daddy Jarred to come clean up his mess, and Jarred is 100% able to deliver.
This doesn't make as much sense. OpenAI has a better low level engineering team and they don't have a hot mess with traction like Anthropic did. This seems more about acquiring people with dev ergonomics vision to push product direction, which I don't see being a huge win.

They do have a hot mess with traction amongst developers. Codex is far behind Claude Code (in both the GUI and TUI forms), and OpenAI's chief of applications recently announced a pivot to focus more on "productivity" (i.e. software and enterprise verticals) because B2B yields a lot more revenue than B2C.

I work at OpenAI. Software developers are not obsoleted by Codex or Claude Code, nor will they be soon.
For our teams, Codex is a massive productivity booster that actually increases the value of each dev. If you check our hiring page, you’ll see we are still hiring aggressively. Our ambitions are bigger than our current workforce, and we continue to pay top dollar for talented devs who want to join us in transforming how silicon chips provide value to humans.
Akin to how compilers reduced the demand for assembly but increased the demand for software engineering, I see Codex reducing the demand for hand-typed code but increasing the demand for software engineering. Codex can read and write code faster than you or me, but it still lacks a lot of intelligence and wisdom and context to do whole jobs autonomously.

The "then what" is that their model uses it. Technically superior software loses to popular software on marketing. But LLM owners have the ultimate marketing tool, because they can make their model use the tool. Anyone who asks how to do X in Python gets recommended "OpenAI-Python-Tool-For-X". Anyone who asks Codex to do X, Codex automatically installs "OpenAI-Tool-For-X". It would be very easy for them to launch even technically inferior software into a prime position. On top of that, if software developers are being replaced altogether as we are bashed in the head with such tales again and again, the marketing of dev tools wouldn't even matter, only what models are trained to use.

They are buying out investors, it's like musical chairs.
The liquidity is going to be better on OpenAI, so it pleases everyone (less pressure from investors, more liquidity for investors).
The acquisition is just a collateral effect.
tgtweak 3 hours ago [-]
Are you implying that the revenue multiple on this acquisition is lower than openAIs and that they'd be making money by acquiring and folding into their valuation multiple? I think that's not the case and I would wager non existent.
This was an acquihire (the author of ripgrep, rg, which codex uses nearly exclusively for file operations, is part of the team at Astral).
So, 99% acquihire , 1% other financial trickery. I don't even know if Astral has any revenue or sells anything, candidly.
It means the company almost reached their runway, so all these employees would have to find a job.
It's a very very good product, but it is open-source and Apache / MIT, so difficult to defend from anyone just clicking on fork. Especially a large company like OpenAI who has massive distribution.
Now that they hired the employees, they have no more guarantees than if they made a direct offer to them.
tgtweak 2 hours ago [-]
So I don't see how the acquisition is collateral - it's an acquihire plain and simple, if anything else it would be supply chain insurance as they clearly use a lot of these tools downstream. As you noted the licensing is extremely permissive on the tools so there appears to be very little EV there for an acquirer outside of the human capital building the tools or building out monetized features.
I'm not too plugged into venture cap on opensource/free tooling space but raising 3 rounds and growing your burn rate to $3M/yr in 24 months without revenue feels like a decently risky bag for those investors and staff without a revenue path or exit. I'd be curious to see if OpenAI went hunting for this or if it was placed in their lap by one of the investors.
OpenAI has infamously been offering huge compensation packages to acquire talent, this would be a relative deal if they got it at even a modest valuation. As noted, codex uses a lot of the tooling that this team built here and previously, OpenAI's realization that competitors that do one thing better than them (like claude with coding before codex) can open the door to getting disrupted if they lapse - lots of people I know are moving to claude for non-coding workflows because of it's reputation and relatively mature/advanced client tools.

They want codex to become the "default" coding agent by making it the one integrated into popular open source software.

I think this is more about `ruff` than `uv`. Linting is all about parsing the code into something machines can analyze, which to me feels like something that could potentially be useful for AI in a similar way to JetBrains writing their own language parsers to make "find and replace" work sanely and what not.
I'm sort of wondering if they're going to try to make a coding LLM that operates on an AST rather than text, and need software/expertise to manage the text->AST->text pipeline in a way that preserves the structure of your files/text.

Writing a literal parser isn’t too hard (and there’s presumably an existing one in the source code for the language).
Writing something that understands all the methods that come in a Django model goes way beyond parsing the code, and is a genuine struggle in language where you can’t execute the code without worrying about side effects like Python.
Ty should give them a base for that where the model is able to see things that aren’t literally in the code and aren’t in the training data (eg an internal version of something like SQLAlchemy).

What I don’t understand is why hasn’t anyone bought Jetbrains yet.
Atlassian? AWS? Google?

Because Jetbrain strategy wasn't to burn money with free tools to eventually exit with the jackpot. They have been profitable for over a decade, simply asking users to pay a fair price for great product.

Judging by all their mistakes in the last years, Russian war and AI, it’s only a matter of time until someone buys them out.

Never did. I remember someone replied to my comment here that Google isn’t paying a penny to JetBrains. They’re quite happy with the relationship primarily because they don’t have to pay anything. If anything, JetBrains is the one who needs Google more than the other way around.

More and more plainly, OpenAI and Anthropic are making plays to own (and lease) the "means of production" in software. OK - I'm a pretty happy renter right now.
As they gobble up previously open software stacks, how viable is it that these stacks remain open? It seems perfectly sensible to me that these providers and their users alike have an interest in further centralizing the dev lifecycle - eg, if Claude-Code or Codex are interfaces to cloud devenvs, then the models can get faster feedback cycles against build / test / etc tooling.
But when the tooling authors are employees of one provider or another, you can bet that those providers will be at least a few versions ahead of the public releases of those build tools, and will enjoy local economies of scale in their pipelines that may not be public at all.

Such an outcome would make me wonder regarding the wisdom of "It is better to have love and lost than to have never loved at all."
Note that uv is fast because — yes, Rust, but also because it doesn’t have to handle a lot of legacy that pip does[1], and some smart language independent design choices.
If uv became unavailable, it’d suck but the world would move on.
[1] https://nesbitt.io/2025/12/26/how-uv-got-so-fast.html
This is not the point of uv or any good package manager. The point is what prevents Python to suck. For a long time package management had been horrible in Python compared what you could see in other languages.
- https://pypistats.org/packages/poetry - https://pypistats.org/packages/uv
In the 2024 Python developer survey, 18% of the ecosystem used Poetry. When I opened this manifold question[0], I'm pretty sure uv was about half of Poetry downloads.
Estimating from these numbers, probably about 30% of the ecosystem is using `uv` now. We'll get better numbers when the 2025 Python developer survey is published.

Perhaps it never grabbed me as much because I've been running basically everything in Docker for years now, which takes care of Python versioning issues and caches the dependency install steps, so they only take a long time if they've changed. I also like containers for all of the other project setup and environment scaffolding stuff they roll up, e.g. having a consistently working GDAL environment available instantly for a project I haven't worked on in a long time.

If not, do you develop software with source dependencies (go, java, node, rust, python)? If so, how do you handle acquiring those dependencies—by hand or using a tool?
Mostly no, sometimes I give up and still use pip as a separate user.
> If not, do you develop software with source dependencies (go, java, node, rust, python)? If so, how do you handle acquiring those dependencies—by hand or using a tool
I haven't felt the need to use Go, the only Java software I use is in the OS repo. I don't want to use JS software for other reasons. This is one of the reasons why I don't like Rust rewrites. Python dependencies are very often in the OS repo. If there is anything else, I compile it from source and I curse when software doesn't use or adheres to the standard of the GNU build system.
And let’s say you constrain yourself to your OS package manager. What about the people on different distros? Their package managers are unlikely to have the exact same versions of your deps that your OS has.
I favor stability and the stripping of unwanted features (e.g. telemetry) by my OS vendor over cutting edge software. If I really need that I install it into /usr/local, that it what this is for after all.
> And let’s say you constrain yourself to your OS package manager. What about the people on different distros? Their package managers are unlikely to have the exact same versions of your deps that your OS has.
This is a reason to select the OS. Software shouldn't require exact versions, but should stick to stable interfaces.

I'm on the fence about cancelling my JetBrains subscription I've had for nearly 10 years now. I just don't use it much. Zed and Claude Code cover all my needs, the only thing I need is a serious DataGrip alternative, but I might just sit down with Claude and build one for myself.
It's not perfect, but it is light-years better than what preceded it.
I jumped ship to it and have not looked back. (So have many of my clients).
It's so fast in fact that we just added `ty check` to our pre-commit hooks where MyPy previously had runtimes of 150+ seconds _and_ a mess of bugs around their caching.
Once we start seeing Open AI and Anthropic getting into the certifications and testing they'll quickly become the gold standard. They won't even need to actually test anyone. People will simply consent to having their chat interactions analyzed.
The models collect more information about us than we could ever imagine because definitionally, those features are unknown unknowns for humans. For ML, the gaps in our thinking carry far richer information about is than our actual vocabularies, topics of interest, or stylometric idiosyncrasies.
There will come a day when you can will an entire business into existence at the press of a button. Maybe it has one or two people overseeing the business logic to make sure it doesn't go off the rails, but the point is that this is a 100x reduction in labor and a 100,000x speed up in terms of delivery.
They'll price this as a $1M button press.
Suddenly, labor capital cannot participate in the market anymore. Only financial capital can.
Suddenly, software startups are no longer viable.
This is coming.
The means of production are becoming privatized capital outlays, just like the railroads. And we will never own again.
1. For the record: the GPL is entirely dependent on copyright.
2. If AI "clean-room" re-implementations are allow to bypass copyright/licenses, the GPL won't protect you.
Isn't that the same for the obligations under BSD/MIT/Apache? The problem they're trying to address is a different one from the problem of AI copyright washing. It's fair to avoid introducing additional problems while debunking another point.
2. BigCo bus Company A
3a. usually here BigCo should continue to develop Project One as GPLv3, or stop working on it and the community would fork and it and continue working on it as GPLv3
3b. BigCo does a "clean-room" reimplementation of Project One and releases it under proprietary licence. Community can still fork the older version and work on it, but BigCo can continue to develop and sell their "original" version.
I'm careful to not rely too heavily on VC funded open source whenever I can avoid it.
All so they could just vacuum it all up and resell it with impunity.

> "GitHub wants to help developers choose an open source license for their source code."
This was built by GitHub Inc a very very long time ago.
So long ago, in fact, that it was five years before their acquisition by Microsoft.
The ones pushing for permissive licenses are rather companies like Apple, Android (and to some extent other parts of Google), Microsoft, Oracle. They want to push their proprietary stuff and one way to do that in the face of open source competition is by proprietary extensions.
The FOSS community at large embraced permissive licenses and it had nothing to do with the interests of big corporations.
And, sure, djb wasn't actually likely to sue you if you went ahead and distributed modified versions of his software... but no-one else was willing to take that risk, and it ended up killing qmail, djbdns, etc stone dead. His work ended up going to waste as a result.
The issue that I see is that Nvidia etc. are incentivised to perpetuate that so the open source community gets the table scraps of distills, fine-tunes etc.
If the open weights models are good, there are people looking to sell commodity access to it, much like a cloud provider selling you compute.
It's probably a trade secret, but what's the actual per-user resource requirement to run the model?
As long as they keep the original projects maintained and those aren't just acqui-hires, I think this is almost as good as we can hope for.
(thinking mainly about Bun here as the other one)
Once you’re acquired you have to do what the boss says. That means prioritizing your work to benefit the company. That is often not compatible with true open source.
How frequently do acquired projects seriously maintain their independence? That is rare. They may have more resources but they also have obligations.
And this doesn’t even touch on the whole commodification and box out strategy that so many tech giants have employed.
If AGI becomes available, especially at the local and open-source level, shouldn't all these be democratized - meaning that the AGI can simply roll out the tooling you need.
After all, AGI is what all these companies are chasing.
Equivalent or better tools will pop up eventually, heck if AI is so fantastic then you could just make one of your own, be the change you want to see in the world, right?
Oh well. They’ll hopefully get options and make millions when the IPO happens. Everyone eventually sells out. Not everyone can be funded by MIT to live the GNU maximalist lifestyle.
I maintain an open source project funded by the Sovereign Tech Fund. Getting there wasn't easy: the application process is long, the amounts are modest compared to a VC round, and you have to build community trust before any of that becomes possible. But the result is a project that isn't on anyone's exit timeline.
I'm not saying the startup path is without its own difficulties. But structurally, it offloads the costs onto the community that eventually comes to depend on you. By the time those costs come due, the founders have either cashed out or the company is circling the drain, and the users are left holding the bag. What's happening to Astral fits that pattern almost too neatly.
The healthier model, I think, is to build community first and then seek public or nonprofit funding: NLnet, STF, or similar. It's slower and harder, but it doesn't have a built-in betrayal baked into the structure.
Part of what makes this difficult is that public funding for open source infrastructure is still very uneven geographically. I'm based in Korea, and there's essentially nothing here comparable to what European developers can access. I had no choice but to turn to European funds, because there was simply no domestic equivalent. That's a structural problem worth taking seriously. The more countries that leave this entirely to the private sector, the more we end up watching exactly this kind of thing play out.
Having a private package index gives you a central place where all employees can install from, without having to screen what each person is installing. Also, if I remember right, there are some large AI and ML focused packages that benefit from an index that's tuned to your specific hardware and workflows.
Plus the obvious need for a place to host proprietary internal libraries.
It was because Astral was VC funded.
https://astral.sh/blog/announcing-astral-the-company-behind-...
There seems to be a pervasive believe that the Python tooling and interpreter suck and are slow because the maintainers don’t care, or aren’t capable.
The actual problem is that there isn’t enough money to develop all of these systems properly.
Google says that Astral had 15 team members. Or course, it’s so hard to make these projections. But it wouldn’t shock me if uv and ruff are each individually multi-million dollar pieces of software.
If you’d like to invest a million dollars to improve pip, or work for free for 3 years to do it yourself, I’m not sure if anyone would object.
Either pay for the product, or use stuff that isn't dependent on VC money, this is always how it ends.
Maybe you use non-transitive pure Python dependencies, but it's likely that your tools and dependencies still rely on stuff in Rust or C (e.g.: py-cryptography and Python itself respectively).
As mentioned multiple times, since my experience with Tcl and continuously rewriting stuff in C, I tend to avoid languages that don't come with JIT, or AOT, in the reference tooling.
I tend to work with Java, .NET, node, C++, for application code.
Naturally AI now changes that, still I tend to focus on approaches that are more classical Python with pip, venv, stuff written in C or C++ that is around for years.
At worst, it's just Anaconda II AI Boogaloo. The ecosystems will evolve and overcome, or will die and different ecosystems rise to meet the need going forward.
I anticipate OpenAI will get bored and ignore Astral's tools. Software entropy will do its thing and we will remember an actively developed uv as the good old days until something similar to cargo gets adopted as part of Python's standard distribution.
Consider ffmpeg. You can donate via https://www.ffmpeg.org/spi.html
How much money do they make from donations? I don't know but "In practice we frequently payed for travel and hardware."
Translation: nothing at all.
If such a fundamental project that is a revenue driver for so many companies, including midas-level rich companies like Google, can't even pay decent salaries for core devs from donations, then open source model doesn't work in terms of funding the work even at the smallest possible levels of "pay a reasonable market rate for devs".
You either get people who just work for free or businesses built around free work by providing something in addition to free software (which is hard to pull off, as we've seen with Bun and Astral and Deno and Node).
There are examples of foundations or other similar entities paying developers, like Linux, SQLite, even Zig.
Maybe the difference is some projects rely on core contributors more because external contributions are more restricted in some way.
But sure, the entire open source model doesn't work, lol

OpenClaw notably was built around Mario Zechner's pi[0]; uv I believe was highly adapted from Armin Ronacher's rye[1], and uses indygreg's python-build-standalone[2] for distributing Python builds (both of which were eventually transferred to Astral).

In the worst case, Astral will stop developing their tools, someone else will pick them up and will continue polishing them. In the best case, they will just continue as they did until now, and nothing will really change on that front.
Astral is doing good work, but their greatest benefit for the ecosystem so far was showing what's possible and how it's down. Now everyone can take up the quest from here and continue. So any possible harm from here out will be not that deep, at worst we will be missing out on many more cool things they could have built.
I started using VS Codium, and it feels like using VS Code before the AI hype era. I wonder if we're going to see a commercial version of uv bloated with the things OpenAI wants us all to use, and a community version that's more like the uv we're using right now.

Glad to hear that I am avoiding Microsoft's spam.
I don't really see the value for OAI/Anthropic, but it's nice to know that uv (+ ty and many others) and Bun will stay maintained!
From Astral the (fast) linter and type checker are pretty useful companions for agentic development.
[1] https://x.com/AprilNEA/status/2034209430158619084
The value for Anthropic / OAI is that they have a strong interest in becoming the "default" agent.
The one that you don't need to install, because it's already provided by your package manager.
I think they're more into the extra context they can build for the LLM with ruff/ty.
Embrace, extend, extinguish. Time will tell.
Depends if you think the bubble is going to pop, I suppose. In some sense, independence was insulation.
Probably inevitable, and I don’t blame the team, I just wish it were someone else.
Microsoft acquires Astral
Wish comes with a cost
Sigh
It was a VC backed tool. What did you expect?
Now for those wondering who would fork and maintain it for free, that is more of a critic of FOSS in general.
Seems like the big AI players love buying up the good dev tooling companies.
I hope this means the Astral folks can keep doing what they are doing, because I absolutely love uv (ruff is pretty nice too).
That is definitely the plan!
Only time will tell if it will not affect the ecosystem negatively, best of luck though, I really hope this time is different™.
Congratulations though!
Would be a good mustache-twirling cartoon villain tactics, you know, try to prevent advances in developer experience to make vibecoding more attractive =)
Something like this was always inevitable. I just hope it doesn’t ruin a good thing.
I'm not really sure about this.
If you find your popular, expensive tool leans heavily upon third party tools, it doesn't seem a crazy idea to purchase them for peanuts (compared to your overall worth) to both optimize your tool to use them better and, maybe, reduce the efficacy of how your competitors use them (like changing the API over time, controlling the feature roadmap, etc.) Or maybe I'm being paranoid :-)
In a completely unrelated event, Donald sues Sam for 10M$ for calling him old, Sam grudingly agrees to pay him 16M$ and a beer.
That said, I hope the excellent Astral team got a good payday.
Take ruff, I have used it, but I had no idea it even had a company behind it... And I must not be only one and it must not be only tool like it...
Anthropic acquiring Bun, now OpenAI acquiring Astral. Both show the big labs recognize that great AI coding tools require great developer tooling, and they are willing to pay for it rather than build inferior alternatives. Good outcome for the teams.
Not exactly a great look for the "AGI is right around the corner" crowd — if the labs had it, they would not need to buy software from humans.

Everything I've seen from Astral and Charlie indicates they're brilliant, caring, and overall reasonable folks. I think it's unfair to jump to call them sell-outs and cast uv and the rest as doomed projects.
And framing it as "sell-outs" is cheap rhetoric that means nothing. The fact is, they were the company who never really had a solid business model, but provide a lot of value for the community. Being acquired by some infinite-money company was always the best outcome they could hope for. Well, they did. Probably got a ton of money. Will it require some sacrifice? Well, some people would say that working for a company who makes products for the Department of War of the USA on conditions that even Anthropic found too ugly to satisfy, is enough of a sacrifice on its own. I am pretty sure though that most people would be willing to make this sacrifice for the right amount of money (with "right amount" being a variable part). So calling someone a sell-out is usually just bitterness about the fact that it wasn't you who managed to sell out. I mean, not judging someone for a sacrifice they make isn't the same thing as pretending they didn't make a sacrifice. Sometimes we (the world, they were trying to make better) are a sacrifice. That's all.
(sure, it's a bit different than contributing to CPython, but I'd argue not that different)
I'm a heavy user and instructor of uv. I'm teaching a course next week that features uv and rough (as does my recent Effective Testing book).
Interesting to read the comments about looking for a change. Honestly, uv is so much better than anything else in the Python community right now. We've used projects sponsored by Meta (and other questionable companies) in the past. I'm going to continue enjoying uv while I can.
https://news.ycombinator.com/item?id=47414032
Uv did solve a distribution problem for them.
There is still a lot of room to grow in the space of software packaging and distribution.
Perhaps it's naive optimism, but I generally have hope that new and improved tools will continue to gain adoption and shine through in the training data, especially as post-training and continual learning improve.
Astral has demonstrated that there is desire for this sort of "just works" thing, which I struggled with, and led me to abandoning it. (I.e.: "pip/venv/conda are fine, why do I want this?", despite my personal experience with those as high-friction)
2. In any case, the announcement strongly suggests that customer acquisition had little to do with this. The stated purpose of the acquisition, as I read it, is an acquisition (plus acquihire?) to bolster their Codex product.
3. But if they were hoping for some developer goodwill as a secondary effect... well, see my note above.
Good for Astral though I guess, they do great work. Just not optimistic this is gonna be good for python devs long term.
https://www.cnbc.com/2026/03/17/openai-preps-for-ipo-in-2026...
This doesn't make as much sense. OpenAI has a better low level engineering team and they don't have a hot mess with traction like Anthropic did. This seems more about acquiring people with dev ergonomics vision to push product direction, which I don't see being a huge win.
Fixed: I am so excited to take these millions of dollars.
If it was cheaper to use their internal AI to create these tools, they would.
Agree with OP here, if AI coding tools are as intelligent and amazing as AI influencers and CEOs are saying, just prompt them to "Remake UV but faster & better".
For our teams, Codex is a massive productivity booster that actually increases the value of each dev. If you check our hiring page, you’ll see we are still hiring aggressively. Our ambitions are bigger than our current workforce, and we continue to pay top dollar for talented devs who want to join us in transforming how silicon chips provide value to humans.
Akin to how compilers reduced the demand for assembly but increased the demand for software engineering, I see Codex reducing the demand for hand-typed code but increasing the demand for software engineering. Codex can read and write code faster than you or me, but it still lacks a lot of intelligence and wisdom and context to do whole jobs autonomously.
They could start by inventing any software with their agents. They probably should prove their offering is good enough to do that considering they're hundreds of billions of dollars in debt, owing truckloads of money they currently have no hope of repaying to investors who are being promised a literal revolution.
They are buying out investors, it's like musical chairs.
The liquidity is going to be better on OpenAI, so it pleases everyone (less pressure from investors, more liquidity for investors).
The acquisition is just a collateral effect.
This was an acquihire (the author of ripgrep, rg, which codex uses nearly exclusively for file operations, is part of the team at Astral).
So, 99% acquihire , 1% other financial trickery. I don't even know if Astral has any revenue or sells anything, candidly.
It means the company almost reached their runway, so all these employees would have to find a job.
It's a very very good product, but it is open-source and Apache / MIT, so difficult to defend from anyone just clicking on fork. Especially a large company like OpenAI who has massive distribution.
Now that they hired the employees, they have no more guarantees than if they made a direct offer to them.
I'm not too plugged into venture cap on opensource/free tooling space but raising 3 rounds and growing your burn rate to $3M/yr in 24 months without revenue feels like a decently risky bag for those investors and staff without a revenue path or exit. I'd be curious to see if OpenAI went hunting for this or if it was placed in their lap by one of the investors.
OpenAI has infamously been offering huge compensation packages to acquire talent, this would be a relative deal if they got it at even a modest valuation. As noted, codex uses a lot of the tooling that this team built here and previously, OpenAI's realization that competitors that do one thing better than them (like claude with coding before codex) can open the door to getting disrupted if they lapse - lots of people I know are moving to claude for non-coding workflows because of it's reputation and relatively mature/advanced client tools.
(I work at Astral)
I would sincerely have understood better (and even wished) if OpenAI made you a very generous offer to you personally as an individual contributor than choose a strategy where the main winners are the VCs of the purchased company.
Here, outside, we perceive zero to almost no revenues (no pricing ? no contact us ? maybe some consulting ?) and millions burned.
Whether it is 4 or 8 or 15M burned, no idea.
Who's going to fill that hole, and when ? (especially since PE funds have 5 years timeline, and company is from 2021).
The end product is nice, but as an investor, being nice is not enough, so they must have deeper motives.
What was their pitch?
Bundling codex with uv isnt going to meaningfully affect the number of people using it. It doesnt increase the switching costs or anything.
I'm sort of wondering if they're going to try to make a coding LLM that operates on an AST rather than text, and need software/expertise to manage the text->AST->text pipeline in a way that preserves the structure of your files/text.
https://www.youtube.com/watch?v=l2R1PTGcwrE
Writing something that understands all the methods that come in a Django model goes way beyond parsing the code, and is a genuine struggle in language where you can’t execute the code without worrying about side effects like Python.
Ty should give them a base for that where the model is able to see things that aren’t literally in the code and aren’t in the training data (eg an internal version of something like SQLAlchemy).
Not-most popular LLM software development product on the planet acquires most popular/rapidly rising python packaging org for mindshare.
I guess this move might end up in a situation where the uv team comes up with some new agent-first tooling, which works best or only with OAI services.
Good luck vibe coding marketshare for your new tool.
https://www.cnbc.com/2026/03/03/openai-sam-altman-pentagon-d...
I know I stopped using them.
Ant is building their app distribution platform, so no wonder OpenAI thinking the same, it will only surprise me if they move so slow.
Or are they just using a dartboard?
I hate relying on anything that is controlled by a single company. Considering that Astral is basically brand new in the python timeline, it is concerning that they are already being acquired.
On the other hand, UV is so fast that it makes up for anything I find annoying about it.
One of the bigger pain points I’ve faced in Python is dependency resolution. conda could take 30-60 minutes in some cases. uv took seconds.
A serious quality of life improvement.
Who's organizing a fork, or is python back to having only shitty packaging available? :(

> I started Astral to make programming more productive.
And now they help make killing more productive
Although Astral being VC funded was already headed this way anyway.
Deno, Pydantic (Both Sequoia) will go the same way as with many other VC backed "open source" dev tools.
It will go towards AI companies buying up the very same tools, putting it in their next model update and used against you.
Rented back to you for $20/mo.
But the pressure because they raised VC funding, I would imagine Astral needed an actual exit and OpenAI saw Astral's tools as an asset.
what can I say?
Any good alternatives to uv/plans for community fork of uv?
Its always hard to really trust these corporate funded open source products, but they've honestly been great.
…but I find it difficult to believe openai owning the corner stone of the python tooling ecosystem is good thing for the python ecosystem.
There is no question openai will start selling/bundling codex (and codex subscriptions) with uv.
I dont think I want my package manger doing that.
Hilarity in the comments will ensue
I am not even sure how to feel about this news but feel a bit disappointed as a user even if I might be happy for the devs that they got money for such project but man, I would've hoped any decent company could've bought them out rather than OpenAI of all things.
Maybe OpenAI wants to buy these loved companies to lessen some of the hate but what its doing is lessening the love that we gave to corporations like astral/uv sadly, which is really sad because uv is/(was?) so cool but now we don't know where this tool might be headed next given its in the hands of literally OpenAI :(
"But he owns a tooling company. WHY can't I have that? :( :("
Have not tried it too much yet because I was pretty content with `uv`, but I've heard lots of good things about it
https://news.ycombinator.com/newsguidelines.html
While I do see that the tone of the comment was stingy, it was aimed towards the frustration I have experienced while developing for Python and this piece of news as well.
I didn't see it as a bad thing as it not really aimed at anybody in particular, more like an opinion on Python's shortcomings.
I will try to post more substantive/less emotional comments going forward.
This is a massive backward step for the Python ecosystem, but it's not like a hundred-billion dollar company will care about that.
OpenAI is Microslop, so it's the classic EEE, nothing new to see
