voidzerodev released tsrs, a Rust port (not a fork) of the TypeScript compiler built in close collaboration with the TypeScript team:
- Up to 8x faster than TS 7.0 with 70% less memory
- Runs in WASM, working in browsers and on Workers
- Soon part of the Oxc toolchain
- Try it with npx tsrs
One developer migrating the ChatGPT codebase reports 70% improvements in both wall time and peak CPU/memory usage — especially useful for running concurrent agents/worktrees at scale.
