Flake8 and PyLint are commonly used, and very useful, linting tools: they can help you find potential bugs and other problems with your code, aka “lints”. But they can also be slow. And even if they’re fast on your computer, they may still be slow in your CI system (GitHub Actions, GitLab, or whatever else.)
Happily, there’s a new linter available, Ruff, which is much faster. And it supports many of the same lints, including those from many of Flake8’s plugins.
In this article we’ll get a sense of why Ruff’s extra linting speed is so useful compared to the alternatives.
