Danger is a Ruby-based tool that runs during CI to automate code review chores, letting teams codify pull request etiquette rules like enforcing CHANGELOGs or JIRA links. It offers a DSL and plugin system for building team-specific review rules across GitHub, GitLab, and Bitbucket.
Use cases
- automate pull request checks in CI
- enforce changelog updates on PRs
- require JIRA or Trello links in PR descriptions
- flag common code review anti-patterns automatically
- post automated review comments on pull requests
- codify team code review norms
When to choose
- your team wants to automate repetitive code review chores
- you use GitHub, GitLab, or Bitbucket with CI
- you want a Ruby DSL and plugin ecosystem for PR rules
When to avoid
- you need a non-Ruby toolchain (consider danger-js or danger-swift)
- your CI has no access to the code hosting platform API
- you only need simple linting rather than PR-level rules
