Hey OSDev community,

I’ve been working on LavaOS, a small Unix-like operating system, designed to be developer-friendly and minimal. :D

Key features:
  • Minimal kernel with full framebuffer graphics and window manager.
  • Initramfs is supported. All apps run separately from the kernel.
  • Dynamic shell and terminal emulator – no hardcoded commands.
  • Friendly panic handling, user-readable messages, similar to Windows BSOD.
I built it as a learning and experimental OS, but it’s actually usable for testing kernel features, experimenting with graphics, and practicing OS development.

You can check it out here: https://github.com/LavaOS/LavaOS

Below are some screenshots:

Would love feedback, suggestions, or just people to try it out
