Ruff is so fast that sometimes I add an intentional bug in the code just to confirm it's actually running.

Sebastián Ramírez

Creator of FastAPI

Why is Ruff a gamechanger? Primarily because it’s nearly 1000x faster. Literally. Not a typo.

Nick Schrock

Founder of Elementl, co-creator of GraphQL

Just switched my first project to Ruff. Only one downside so far: it's so fast I couldn't believe it was working until I intentionally introduced some errors.
