stc is a TypeScript type checker written in Rust, aiming to be a much faster alternative to tsc while matching its behavior. The project is officially abandoned and never reached a stable release.

Use cases

  • type-check typescript files faster than tsc
  • integrate a fast typescript type checker into a rust toolchain
  • build a custom typescript language server
  • run type checking in ci with lower latency
  • check typescript code with isolatedModules semantics

When to choose

  • you need a fast, embeddable TypeScript type checker in Rust and accept experimental quality
  • you want to fork or build upon a Rust-based tsc alternative

When to avoid

  • you need a production-ready, fully compatible TypeScript type checker today
  • you expect ongoing maintenance or bug fixes
  • you rely on namespaces or non-isolatedModules features
