Ruff is a relatively new linter for Python. When it comes to linters, for us the question is not whether to use a linter but which linter to use. Ruff stands out for its out-of-box experience and its speed. It has more than 500 built-in rules and readily replaces Flake8, including many of that linter's plugins. The Ruff team’s claims about its performance are borne out by our experience; it really is at least an order of magnitude faster than other linters which is a huge benefit, because it helps reduce build times on large codebases. For these reasons, Ruff has become our default choice as a Python linter.
Ruff is a new linter for Python. For us, the question is not whether to use a linter or not but which linter to use, and there are several choices for Python. Ruff stands out for two reasons: its out-of-box experience and its speed. It has over 500 rules built in and readily replaces Flake8, including many of that linter's plug-ins. The claims by the team behind Ruff about its performance are borne out by our experience. It really is at least an order of magnitude faster than other linters, which is a huge benefit because it helps reduce build times on large codebases.
