Building Astral: Ruff, uv, and other high-performance Python tools, written in Rust.
- Today, we’re announcing the preview release of ty, an extremely fast type checker and language server for Python, written in Rust. In early testing, it's 10x, 50x, even 100x faster than existing type checkers. (We've seen >600x speed-ups over Mypy in some real-world projects.)

- Like Ruff and uv, we're building this project in the open alongside a community of contributors -- over a thousand PRs in total across 30+ authors. So first: thank you to everyone that's contributed to ty over the past few months!
