mateOS is a minimal educational 32-bit x86 operating system in C (with Rust planned), largely vibe-coded with Claude by an author with a little prior experience. It boots via multiboot into full protected mode and has multitasking, a windowing system and networking. The author was surprised how much got done in so little time.
