jasonkneen · x · 2026-11-01
Developer lassejlv released pi-rs, an open-source Rust port of pi, the minimal extensible coding agent harness (120 stars on GitHub). It replaces the JS engine with rquickjs for up to 10x faster performance.
- Builds a single native pi binary with identical CLI, terminal UI, on-disk formats (sessions, settings, auth.json, models.json), RPC protocol, and extension API as the TypeScript version
- No Node.js or Bun needed at runtime; TypeScript extensions run on an embedded JavaScript engine
- Requires Rust 1.88+; installable via cargo install --path crates/pi-coding-agent
