Codemod Registry is a centralized hub for discovering and sharing codemods, making them easily accessible to open-source communities and teams of any size.

Developers can create codemods using engines like ast-grep (recommended), jscodeshift, and ts-morph, and publish them directly to the registry for global distribution.

Published codemods are accessible via web and CLI, with public codemods available to everyone and private ones restricted to an organization’s team.

Codemods with a green badge are officially approved by project owners (e.g., Node.js, React), to offer developers a trustworthy resource with analytics like run counts to identify the best codemods they for their needs. If you are a framework/library builder or maintainer and would like to streamline your users’ migration process, please get in touch with us via Slack or our contact page.
