Ruff

An extremely fast Python linter, written in Rust.

⚡️ 10-100x faster than existing linters
🐍 Installable via pip
🛠 pyproject.toml support
🤝 Python 3.11 compatibility
📦 Built-in caching, to avoid re-analyzing unchanged files
🔧 Autofix support, for automatic error correction (e.g., automatically remove unused imports)
📏 Over 500 built-in rules
⚖️ Near-parity with the built-in Flake8 rule set
🔌 Native re-implementations of dozens of Flake8 plugins, like flake8-bugbear
⌨️ First-party editor integrations for VS Code and more
🌎 Monorepo-friendly, with hierarchical and cascading configuration

> Ruff is so fast that sometimes I add an intentional bug in the code just to confirm it's actually running and checking the code.
