egos-2000 is a teaching operating system implemented in exactly 2000 lines of C and assembly that runs on QEMU and RISC-V boards. It is designed so students can read all of its code, and is accompanied by the EGOS book with nine course projects.

Use cases

• learn how an operating system works by reading all its code
• teach an undergraduate OS course with hands-on projects
• study RISC-V privileged architecture and kernel internals
• run a minimal OS on QEMU for experimentation
• implement OS course projects like file systems and system calls

When to choose

• you want a tiny, fully readable OS codebase for education
• you are teaching or taking an operating systems course on RISC-V
• you prefer minimal code over production complexity

When to avoid

• you need a production-grade or general-purpose operating system
• you require broad hardware support beyond RISC-V and QEMU
• you need features like SMP, networking stacks, or security hardening
