Buz offers a Bun fork built with Zig, achieving sub‑second incremental builds

Buz is a community project that forks the Bun JavaScript runtime. It rewrites core components using the Zig programming language. The change enables incremental builds that complete in under one second. Developers highlight the performance gains over the original Bun implementation. The project aims to serve as a drop‑in replacement for existing Bun users. Source code and discussion are hosted on a Zig‑focused forum. Early benchmarks show reduced build times and lower resource usage. The community encourages testing the fork and contributing to its development.
