I maintain this one. I was the #2 contributor on the original repo, and Siddharth linked here from his README when he archived it.

Nine releases since June. Biggest change is the compositor: it used to run in Electron, now it's native (D3D11, Metal, Vulkan). Export on my test machine went from about 10 fps to about 126. Linux got a lot of work too, and there are in-place updates now, plus Microsoft Store / Fedora / Nix / AUR packages.

Happy to answer questions.
