Ruff
Docs | Playground
An extremely fast Python linter and code formatter, written in Rust.
Linting the CPython codebase from scratch.
* ⚡️ 10-100x faster than existing linters (like Flake8) and formatters (like Black)
* 🐍 Installable via pip
* 🛠️ pyproject.toml support
* 🤝 Python 3.14 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 900 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
Ruff aims to be orders of magnitude faster than alternative tools while integrating more functionality behind a single, common interface.
Ruff can be used to replace Flake8 (plus dozens of plugins), Black, isort, pydocstyle, pyupgrade, autoflake, and more, all while executing tens or hundreds of times faster than any individual tool.
Ruff is extremely actively developed and used in major open-source projects like:
* Apache Airflow
* Apache Superset
* FastAPI
* Hugging Face
* Pandas
* SciPy
...and many more.
Ruff is backed by Astral, the creators of uv and ty.

Testimonials
Sebastián Ramírez, creator of FastAPI:
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.
Nick Schrock, founder of Elementl, co-creator of GraphQL:
Why is Ruff a gamechanger? Primarily because it is nearly 1000x faster. Literally. Not a typo. On our largest module (dagster itself, 250k LOC) pylint takes about 2.5 minutes, parallelized across 4 cores on my M1. Running ruff against our entire codebase takes .4 seconds.
Bryan Van de Ven, co-creator of Bokeh, original author of Conda:
Ruff is ~150-200x faster than flake8 on my machine, scanning the whole repo takes ~0.2s instead of ~20s. This is an enormous quality of life improvement for local dev. It's fast enough that I added it as an actual commit hook, which is terrific.
Timothy Crosley, creator of isort:
Just switched my first project to Ruff. Only one downside so far: it's so fast I couldn't believe it was working till I intentionally introduced some errors.
Tim Abbott, lead developer of Zulip (also here):
This is just ridiculously fast... ruff is amazing.

You can also install Ruff via Homebrew, Conda, and with a variety of other package managers.
Usage
To run Ruff as a linter, try any of the following:
ruff check # Lint all files in the current directory (and any subdirectories).
ruff check path/to/code/ # Lint all files in `/path/to/code` (and any subdirectories).
ruff check path/to/code/*.py # Lint all `.py` files in `/path/to/code`.
ruff check path/to/code/to/file.py # Lint `file.py`.
ruff check @arguments.txt # Lint using an input file, treating its contents as newline-delimited command-line arguments.
Or, to run Ruff as a formatter:
ruff format # Format all files in the current directory (and any subdirectories).
ruff format path/to/code/ # Format all files in `/path/to/code` (and any subdirectories).
ruff format path/to/code/*.py # Format all `.py` files in `/path/to/code`.
ruff format path/to/code/to/file.py # Format `file.py`.
ruff format @arguments.txt # Format using an input file, treating its contents as newline-delimited command-line arguments.
Ruff can also be used as a pre-commit hook via ruff-pre-commit:
- repo: https://github.com/astral-sh/ruff-pre-commit
# Ruff version.
rev: v0.16.2
hooks:
# Run the linter.
- id: ruff-check
args: [ --fix ]
# Run the formatter.
- id: ruff-format
Ruff can also be used as a VS Code extension or with various other editors.
Ruff can also be used as a GitHub Action via ruff-action:
name: Ruff
on: [ push, pull_request ]
jobs:
ruff:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v4
- uses: astral-sh/ruff-action@v3
Configuration
Ruff can be configured through a pyproject.toml, ruff.toml, or .ruff.toml file (see: Configuration, or Settings for a complete list of all configuration options).
For the complete list of enabled rules, see Default Rules.
If left unspecified, Ruff's default configuration is equivalent to the following ruff.toml file:
# Exclude a variety of commonly ignored directories.
exclude = [
" .bzr " ,
" .direnv " ,
" .eggs " ,
" .git " ,
" .git-rewrite " ,
" .hg " ,
" .ipynb_checkpoints " ,
" .mypy_cache " ,
" .nox " ,
" .pants.d " ,
" .pyenv " ,
" .pytest_cache " ,
" .pytype " ,
" .ruff_cache " ,
" .svn " ,
" .tox " ,
" .venv " ,
" .vscode " ,
" __pypackages__ " ,
" _build " ,
" buck-out " ,
" build " ,
" dist " ,
" node_modules " ,
" site-packages " ,
" venv " ,
]
# Same as Black.
line-length = 88
indent-width = 4
# Assume Python 3.10
target-version = " py310 "
[lint]
# select = [...] # See the Default Rules page for the full listing.
ignore = []
# Allow fix for all enabled rules (when `--fix`) is provided.
fixable = [ " ALL " ]
unfixable = []
# Allow unused variables when underscore-prefixed.
dummy-variable-rgx = " ^(_+|(_+[a-zA-Z0-9_]*[a-zA-Z0-9]+?))$ "
[format]
# Like Black, use double quotes for strings.
quote-style = " double "
# Like Black, indent with spaces, rather than tabs.
indent-style = " space "
# Like Black, respect magic trailing commas.
skip-magic-trailing-comma = false
# Like Black, automatically detect the appropriate line ending.
line-ending = " auto "
Note that, in a pyproject.toml, each section header should be prefixed with tool.ruff. For example, [lint] should be replaced with [tool.ruff.lint].
Some configuration options can be provided via dedicated command-line arguments, such as those related to rule enablement and disablement, file discovery, and logging level:
ruff check --select F401 --select F403 --quiet
The remaining configuration options can be provided through a catch-all --config argument:
ruff check --config " lint.per-file-ignores = {'some_file.py' = ['F841']} "
To opt in to the latest lint rules, formatter style changes, interface updates, and more, enable preview mode by setting preview = true in your configuration file or passing --preview on the command line. Preview mode enables a collection of unstable features that may change prior to stabilization.
See ruff help for more on Ruff's top-level commands, or ruff help check and ruff help format for more on the linting and formatting commands, respectively.
Rules
Ruff supports over 900 lint rules, many of which are inspired by popular tools like Flake8, isort, pyupgrade, and others. Regardless of the rule's origin, Ruff re-implements every rule in Rust as a first-party feature.
By default, Ruff enables rules from the F, E, B, UP, and RUF categories, as well as many more, omitting any stylistic rules that overlap with the use of a formatter, like ruff format or Black.
If you're just getting started with Ruff, the default rule set is a great place to start: it catches a wide variety of common errors (like unused imports) with zero configuration. See Default Rules for the complete list.
Beyond the defaults, Ruff re-implements some of the most popular Flake8 plugins and related code quality tools, including:
* autoflake
* eradicate
* flake8-2020
* flake8-annotations
* flake8-async
* flake8-bandit (#1646)
* flake8-blind-except
* flake8-boolean-trap
* flake8-bugbear

* flake8-self
* flake8-simplify
* flake8-slots
* flake8-super
* flake8-tidy-imports

Acknowledgements
Ruff's linter draws on both the APIs and implementation details of many other tools in the Python ecosystem, especially Flake8, Pyflakes, pycodestyle, pydocstyle, pyupgrade, and isort.
In some cases, Ruff includes a "direct" Rust port of the corresponding tool. We're grateful to the maintainers of these tools for their work, and for all the value they've provided to the Python community.
Ruff's formatter is built on a fork of Rome's rome_formatter, and again draws on both API and implementation details from Rome, Prettier, and Black.
Ruff's import resolver is based on the import resolution algorithm from Pyright.
Ruff is also influenced by a number of tools outside the Python ecosystem, like Clippy and ESLint.
Ruff is the beneficiary of a large number of contributors.
Ruff is released under the MIT license.
