Score: 7.3/10 (Innovation: 8, Technical: 9, Documentation: 7, Utility: 5)

kcc is a C17 compiler written entirely in ARM64 assembly as a literate program, with the source itself being a ~1000-page PDF book. It self-hosts, cross-compiles to x86-64, and can build real software like Lua, SQLite, DOOM, and even boot a Linux kernel. The project is technically impressive but niche due to its unusual language and documentation format.

Target audience: compiler enthusiasts, systems programmers, educators
