Get fast, repeatable source code refactoring

OpenRewrite (founded and managed by Moderne) is an automated refactoring ecosystem that enables developers to effectively eliminate technical debt within their repositories. It consists of an auto-refactoring engine that runs prepackaged refactoring recipes for common framework migrations, security fixes, and stylistic consistency tasks.

OpenRewrite is offered under a tiered licensing model. See Licensing for how the framework, parsers, and recipes are licensed.

Start with the quickstart guide and let OpenRewrite handle the boring parts of software development for you. We also welcome you to join our community Slack.
