Bugbot vs Sourcery: Features, Pricing and User Reviews 2026
What are Bugbot and Sourcery?
Bugbot is an AI powered code review tool built by Cursor. It checks every pull request on GitHub and GitLab to catch logic bugs, security issues, and edge cases before code gets merged. Instead of flagging small style problems, it focuses on real bugs that engineers would actually want to fix.
Bugbot reads the code changes along with the surrounding context, then leaves clear comments right inside the pull request explaining what is wrong and how to fix it.
Teams can also write custom rules so Bugbot checks for their own coding standards. It works alongside human reviewers, giving a fast first pass so teams can ship code with more confidence and less manual review work.
Sourcery is an AI coding assistant that reviews your code, catches bugs, and suggests fixes before they cause problems. It works inside your IDE and automatically reviews every pull request on GitHub or GitLab, giving you clear summaries, diagrams, and line by line comments.
Started as a Python refactoring tool, Sourcery has grown into a full platform with continuous security scanning, custom review rules, and an AI chat assistant that understands your code.
Free for public and open source repos, it is trusted by more than 300,000 developers. Whether you are working solo or as part of a large team, Sourcery helps you write safer, cleaner code without slowing down your workflow.
