Show HN: We made Arcad, a parametric CAD in the browser, free and no signup

https://app.arcad.studio/
3•steinvakt2•57m ago
My friend and I have been working on Arcad for some months now. It's a free browser-based parametric CAD tool aimed at hobbyists and makers.

It has editable feature history, solid modeling powered by OpenCascade, STEP export and touch controls for tablets, although it's primarily made for PC use. Everything runs in the browser and you can try it without creating an account or installing anything.

Currently in beta although we feel like it's ready for a full launch. Any feedback is appreciated!

Nice but why in the browser. This is very bad decision - software is not a web page. I should not depend on internet and servers to use my tools, and what I create should stay on my machine only until I decide otherwise. Decisions like this reduce freedom step by step for all humanity!

It works offline and the files are stored locally on your own computer. I agree with your sentiment and that's actually why we built it like this. Browser gives multiple device support, faster incremental updates, bug fix etc. And it gives an easy way to share/cooperate/review with other people
