Judgement

What it is
Developer tool
What it does
A Python linter that combines pyflakes, pycodestyle and the mccabe complexity checker, extended by a large set of third-party plugins.
Adopt it when
An existing Python project relies on specific Flake8 plugins that Ruff does not replicate.
Watch out
Ruff reimplements most of its rules far faster, and Flake8 still does not read configuration from pyproject.toml.
