Refactoring at scale with Moderne
OpenRewrite's refactoring engine and recipes will always be open source. Build tool plugins like OpenRewrite Gradle Plugin and OpenRewrite Maven Plugin help you run these recipes on one repository at a time. Moderne is a complementary product that executes OpenRewrite recipes at scale on hundreds of millions of lines of code and enables mass committing of results. Moderne freely runs a public service for the benefit of thousands of open source projects.
