  6. zigmkv

  7. yuku

    High-performance JavaScript/TypeScript compiler and toolchain in pure Zig 🦎

    Project mention: Yuku – A fast, spec-compliant JavaScript parser written in Zig | news.ycombinator.com | 2026-04-09

    I've been working on Yuku for the past 6 months, a JavaScript parser written in Zig that produces the same AST as Oxc.

    Performance-wise, it's competitive with Oxc as a native Zig library and 3–5x faster than alternatives when used via npm on Node.js, including Oxc's Node bindings.

    It's fully spec-compliant, MIT-licensed, and designed to bring modern JS tooling into the Zig ecosystem.

    Repo: https://github.com/yuku-toolchain/yuku
