Credo vs SwiftLint
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.

SwiftLint provides configurable Swift style checks across several development and CI integrations. Its source-validity and toolchain requirements matter, particularly when using autocorrection or analyzer rules.
