Ruff is a Python linter and code formatter built in Rust, designed to replace multiple tools including Flake8, Black, isort, pydocstyle, pyupgrade, and autoflake. It runs 10-100x faster than traditional linters and formatters while providing drop-in compatibility with their rule sets.
The tool includes over 900 built-in rules, automatic error fixing, built-in caching, pyproject.toml support, and editor integrations for VS Code. It's used by major projects like FastAPI, Pandas, Hugging Face, and Apache Airflow. Installable via pip and compatible with Python 3.15.
