| Configuration | Credo uses a `.credo.exs` configuration file that can be placed in the project root or its `config/` folder. | Project configuration can be stored in setup.cfg, tox.ini, or .flake8 using INI format. |
| Installation | The docs recommend adding Credo as a Mix dependency with `only: [:dev, :test]` and `runtime: false`. | The official quickstart installs Flake8 with python -m pip install flake8 and recommends invoking the interpreter-specific module when multiple Python versions are installed. |
| Purpose | Credo is a static code analysis tool for Elixir focused on code consistency and teaching. | Flake8 combines pycodestyle, pyflakes, McCabe, and third-party plugins to check Python code style and quality. |
