Credo vs pycodestyle
Both stand on linters. Which one you can start free with, which one lets you read the code, and what each costs once you pay.
Free plan
Credo combines Elixir code checks with explanations intended to help users understand and configure findings. Its CLI output, custom checks and CI exit status support both local review and pipeline use.

Choose pycodestyle for free, configurable checks of selected PEP 8 conventions, especially when editor navigation or plugin extensions matter. Look elsewhere or use plugins or related tools if you need exhaustive rule coverage, naming or docstring checks, or automatic fixing.
