About Sourcery
Sourcery started as a Python refactoring tool and is now an AI code review service. It reviews pull requests on GitHub and GitLab with comments, summaries and diagrams, suggests one-click fixes, follows custom review rules, and can auto-approve low-risk changes. A security product adds checks on every pull request and, on the Team plan, nightly scans across repositories with an issues dashboard. Pricing is straightforward and lower than many rivals: reviews on public repositories are free forever, a Pro plan per developer covers private repositories, and a Team plan adds security scanning and analytics. Enterprise offers self-hosting, GitHub Enterprise Server, SSO and bring-your-own LLM keys. There's a 14-day trial with no credit card. It suits small and mid-sized teams that want AI review without a big bill, and open-source maintainers.
Best for: Small teams and open-source maintainers who want affordable AI pull request reviews.
