About:
Ty is a next-generation Python type checker built in Rust for exceptional performance. It provides rapid feedback during development by quickly identifying type errors and improving code reliability. Its speed makes it suitable for large codebases where traditional type checkers may be slow.
Key Features:
  • Extremely fast execution due to Rust implementation
  • Accurate type error detection
  • Minimal configuration required
  • Suitable for large Python projects
Use Cases:
  • Continuous integration pipelines requiring fast type checking
  • Local development for immediate type error feedback
  • Large codebase maintenance and refactoring
Alternatives:
  • mypy – More mature and feature-rich but significantly slower
  • pyright – Fast but requires Node.js runtime
