What Sourcery is

Sourcery is an AI code review and refactoring platform. It supports a wide range of programming languages, integrates with GitHub, GitLab and mainstream IDEs, and provides instant feedback, PR summaries, review guides and visual change views.

A built-in coding assistant generates tests, documentation, code explanations and refactoring suggestions, and the platform supports custom review rules and learning from team feedback. Zero code retention and self-hosted deployment are offered.

What you can do with it

  • Review a pull request before a human looks at it
  • Get refactoring and readability suggestions
  • Generate tests and docs
  • Enforce team review standards

Who it is for

  • Teams wanting faster review cycles
  • Tech leads reducing duplicate review work
  • Organisations with data retention requirements

What to watch out for

  • Findings can be wrong or noisy without tuned rules
  • Self-hosting adds operations work
  • Confirm current language coverage and plan limits
