The name is really cool

The appimage seems solid for me thus far, installed through this handy tool.

You may find yourself interested in suckless software, take a look here.

Its all written and configured with C, so it should be pretty fast. And there’s dwm, their dynamic tiling window manager.

I guess the distro/package manager would be whatever you want, as suckless software encourages that you build from source and maintain your version of the software.
