a performance-first TypeScript checker written in Rust. Started 5 months ago and it's been mostly AI-written code.
99.8% tsc conformance test pass rate today. Single file benchmarks are 3–5x faster than tsgo.
You can see LSP working in the playground. It is still WIP but pretty fast. I'll add LSP benchmarks later. My design is highly biased towards fast incremental checks
