What is the geometry kernel? That's always the first question I have.

Thanks for asking. Core ops are OCCT. It's got great primitives and tolerant modeling. For performance purposes, I've implemented my own algorithms for hidden line rendering, tessellation, and others. I've spent my whole career (15 years+) working on and around kernels.
More detail for the curious: it’s C++ compiled to WebAssembly and runs entirely client-side with a WebGL2 renderer, so there’s no server round-trip for geometry. OCCT does booleans, fillets, and STEP. I replaced its mesher with my own tessellator because BRepMesh was the bottleneck at scale, and hidden-line/Make2D are custom too. Happy to go deeper on any of it.

Product aside, it's nice to see what seem like real answers over equivocality. Wishing you the best of luck!

Aw thanks! I spent longer than I wish to mention on this.

Congratulations on launching.
I would not bet a business that depends on CAD on something that only costs $19/month. Even if it didn't require taking a dependency on a website.
Or to put it AutoCad is cheaper than being sued. Good luck.

Fair concern, and it’s the right question to ask of any new tool. A few concrete answers:
Your work isn’t trapped. Drawings export to DWG, DXF, PDF, and STEP at any time, and you can save the native file locally. If Aircad vanished tomorrow, your drawings open in AutoCAD.
The engine runs in your browser, not on our servers. Modeling and drafting don’t round-trip to a server, so it’s fast and isn’t fragile the way server-side CAD is.
On liability: the professional of record carries it whatever the tool. AutoCAD’s license disclaims it too. What a firm needs from software is accuracy, standard formats, and an exit path, and that last one is why DWG round-tripping got so much of my time.
The price is low because a small team building on modern infrastructure has much lower costs, not because corners were cut.

As a related note, reading lots of "I built" here is not confidence inspiring, no matter how good you are. There's always that bus factor thing.

That’s fair, and it’s the right thing to weigh with any new tool. Right now it’s a small company and I’ve written most of the engine. What I’ve tried to make sure is that your work never depends on Aircad surviving. Everything exports to DWG, DXF, PDF, and STEP whenever you want, and you can keep native files locally, so the exit path is always open. The engine also runs entirely in your browser, not on our servers. I’d rather earn trust over time than ask for it up front.
