How it works
The tool's strength is judgement, not just rules: it explains why a change is better, applies refactoring suggestions directly in the IDE through extensions for VS Code and PyCharm, and lets teams set custom coding guidelines so reviews match their own standards. The Team plan adds a repository analytics dashboard, daily security scans, and the option to bring your own language model.
Sourcery is free for open-source projects on public repositories, with no seat limits. Private repositories need the Pro plan at $10 per user per month, and the Team plan at $24 adds security scanning and analytics; annual billing cuts both by about 20%. Python teams get the most from it, since that is where its refactoring engine is strongest, but it is a solid, affordable reviewer for any team.
