CORS Pilot is a Chrome add-on designed specifically for web developers to fix CORS issues encountered during local development. This free tool offers a whitelist-first approach, ensuring that only specified domains like localhost andare affected, preventing accidental disruptions to other sites. It features tab-scoped activation for one-off debugging sessions, with an automatic 30-minute timeout to minimize risks of leaving it enabled unintentionally.

The extension includes a user-friendly interface with a toolbar badge that indicates the current state of CORS rewriting. Developers can monitor modifications in real-time through a dedicated DevTools panel. With built-in safety measures, CORS Pilot avoids sensitive domains, ensuring that critical sites remain untouched. Built with Manifest V3 support, it guarantees compliance with future Chrome updates while maintaining user privacy through zero data collection.
