Ruff aims to be orders of magnitude faster than alternative tools while integrating more
functionality behind a single, common interface.

- ⚡️ 10-100x faster than existing linters (like Flake8) and formatters (like Black)
- 🐧 Installable via snap
- 🛠️ pyproject.toml support
- 🤝 Python 3.12 compatibility
- ⚖️ Drop-in parity with Flake8, isort, and Black
- 📦 Built-in caching, to avoid re-analyzing unchanged files
- 🔧 Fix support, for automatic error correction (e.g., automatically remove unused imports)
- 📏 Over 700 built-in rules, with native re-implementations of popular Flake8 plugins, like flake8-bugbear
- ⌨️ First-party editor integrations for VS Code and more
- 🌎 Monorepo-friendly, with hierarchical and cascading configuration
