| Best use | Best for an individual Python developer or small team that wants consistent linting, import organization, and formatting locally, in editors, and in CI. It adds reviewable rules, safe-by-default fixes, and a pinnable version. It does not replace tests, type checking, or business-logic review, and migration from Black or Flake8 should be tested on a branch. | For developers reviewing features as small changes and revisiting earlier steps. Start with a separate practice clone to learn working copies and Bookmarks; delay team adoption until compatibility with required Git tooling is checked. | Ideal for a solo developer or small team that wants API collections and tests beside the code with Git review. Use it for repeatable REST, GraphQL, gRPC, and WebSocket checks—not live cloud collaboration or load testing. |
