What is SavaOS?

SavaOS is a 32-bit x86 GitHub project delivering a complete operating system from scratch, with a VGA GUI desktop, window manager, terminal shell, and FAT32 disk support. Built in C and 32-bit x86 assembly on a no-libc, no-Linux foundation, it boots in QEMU to a clickable interface running apps like notepad (with undo/save), calculator, file browser, and puzzle—persisting files to a virtual 64MB disk image.

Why is it gaining traction?

It packs a responsive 320x200 desktop, PS/2 mouse/keyboard, ATA IDE reads/writes, and 20+ shell commands (ls, cat, mkdir, rm) into ~17k lines, runnable in seconds via make run. Developers love extending it—add apps via menu registration, tweak palettes, or debug via GDB stub—without 32-bit x86 calling convention headaches or dependencies.

Who should use this?

OSdev hobbyists dissecting 32-bit x86 registers and protected mode, students building custom kernels on 32-bit x86 architecture, or retro hackers porting DOS-era tools to a modern QEMU setup.

Verdict

Grab it for learning bare-metal OSes (1.0% credibility, 11 stars signals early days), with stellar README screenshots and build targets—but expect rough edges like partial control panel and no networking. Ideal starter for 32-bit x86 assembly experiments; production? Wait for DOOM port.
