One of the largest pure-Rust sovereignty stacks in history.
The official COOLJAPAN Pure Rust Ecosystem — 603 crates, ~24M SLoC, zero C/FFI (in default) · Memory-safe by design. We are rebuilding the entire scientific, media, AI, semantic web, formal verification, and systems stack in pure Rust — so AI agents and critical software can run anywhere with full sovereignty.
- Total crates: 603 (and growing daily)
- Total Rust SLoC: ~24 million
- Passing tests: 270,000+
- Projects: 40+ production-grade libraries
- All projects: 100%
