Sourcery
AI code reviewer focused on refactoring and code quality rather than bug detection. Identifies opportunities for cleaner patterns, suggests simplifications, and assigns quality scores to track improvements over time. Strong Python and JavaScript support. Asks "is this code well-written?" rather than "is this code correct?" — helping teams prioritize maintainability and readability.
