Sourcery

Sourcery is an AI code review platform focused on the pull-request bottleneck. It installs as a GitHub, GitLab, or Bitbucket app and reviews every incoming PR: it summarizes the change, posts inline suggestions for bugs, security issues, and style violations, and offers refactor recommendations to reduce complexity. Sourcery understands team-defined coding rules — teams can codify "never call database.py from a controller" or "async functions must have a timeout" in a YAML config, and Sourcery enforces them on every review without hallucinating. Where earlier AI reviewers pointed out obvious noise, Sourcery focuses on high-signal comments and lets developers accept a fix with a single click, opening a follow-up commit. Sourcery also ships an IDE extension for VS Code, PyCharm, and JetBrains suites that lets developers see suggestions before pushing. Supported languages include Python, JavaScript, TypeScript, Java, Go, Ruby, and C#. Pricing includes a free tier for open-source repos, a Pro plan at $12/month for individuals, and Team/Enterprise plans starting around $30/user/month with SSO, on-prem, and custom rule packs. Sourcery is popular with engineering leaders trying to speed up code review turnaround without burning senior engineers on stylistic nitpicks.
