ty is an extremely fast Python type checker and language server, written in Rust, and designed as an alternative to mypy, Pyright, and Pylance.

pyx is a Python-native package registry from the creators of uv.

uv is an extremely fast Python package installer and resolver, designed as a drop-in alternative to pip and pip-tools.

The next stable version of Ruff is out now.

Experimental uv-ty integration enables first-class support for Python scripts on the CLI and in the editor, and a unified uv check command.

Ruff adds a versioning policy, fix safety levels, and a preview mode for unstable features.

Manage entire Python projects and even Python itself with a single unified tool.

Astral is taking stewardship of python-build-standalone, Gregory Szorc's foundational project for installing portable Python distributions.
