What is Sourcery?

Sourcery is an AI code-review and refactoring assistant with roots in Python: it reviews pull requests on GitHub, suggests idiomatic refactorings, generates summaries and comments for changes, and chats about your codebase in the IDE or the browser. Its refactoring engine began as a rule-based tool, which keeps many of its suggestions precise and safely applicable.

Teams can define coding guidelines in plain language and have Sourcery check pull requests against them, and it is free for open-source and public repositories. Paid plans cover private code and team features; Python projects still get the deepest refactoring support, and developers wanting autonomous multi-file agents will find Sourcery more of a careful reviewer than a builder.
