SkiftOS: A hobby OS built from scratch using C/C++ for ARM, x86, and RISC-V

What else does it have rather than beautiful UI? Network support? Sound? What file systems does it support? What about multiple users? What about applications isolation?

It would be nice to have such information displayed somewhere on the site.

It’s a microkernel-based operating system. Mostly just a learning/fun side project for me. It implements something akin to the NixOS /store. Hardware, networking, sound, and the file system are all very barebones. Most of the work so far has been put into the framework, some example apps, and the browser.
