At first glance, this looks really impressive.

Which modeling kernel does it use?

Changelog notes seem to hint at MEDUSA, though I've never heard of that particular one. Definitely going to give it a try, always up for more browser based CAD options!

It's one big as single file https://github.com/Nx-Nass/NassCAD/blob/main/MEDUSA_SOURCE/n...

From their Github, it looks like OpenCascade with Manifold for mesh boolean that they are calling MEDUSA.

The Release page has:

>Download the Source code ZIP below and extract it. It includes the application, its libraries and the OpenCASCADE WASM/data files.

Just a one minutes test:

    * Mouse over text takes too long, it should be visible instant. When I'm searching for a tool I don't want to wait 500ms for each symbol
    * Even empty it feels more laggy then onshape on same device / browser.
    * When I did a boolean operation there is no popup or similar where I can choose the tool and target. It's all based on selection order? How do I choose 2 tools and one target, or the other way around.

And it's all based on a single 16 000 large c++ file? https://github.com/Nx-Nass/NassCAD/blob/main/MEDUSA_SOURCE/n...

wut? That whole repo seems a mess.

I'm not sure if it's crashed or just very slow, but I've been waiting several minutes to preview a fillet on a cylinder end.

I'm glad people are working on this. The open source CAD world is not doing well (not you Blender<3) and even if you're willing to pay the big bucks for any of the proprietary options, they won't run on Linux without rather high levels of applied violence.

That leaves cloud only options like on-shape which means they get to hold your project files hostage. I'm not sure why any business has ever come to the conclusion that losing control of their design work is acceptable but here we are.

There is also https://getartcraft.com/apps/cadcraft

One of those new *craft apps that try to clean room copy well known commercial solutions. Though apparently it's currently in a very early stage (buggy)

That's 2D though. For 3D CAD there's SolidCraft.
