Resource Override is a powerful Chrome extension designed to give you complete control over any website you visit. It enables you to redirect URLs dynamically before requests are sent, allowing you to replace resources with your own text documents or unminified code versions for easier debugging and development.

The extension supports injecting JavaScript and CSS files seamlessly and now includes request and response header modification with common presets like enabling CORS, allowing iframes, and more. Resource Override is perfect for developers and testers who need to debug live websites or customize content on the fly without editing the original source.

User reviews

Resource Override is praised for its simplicity, effectiveness, and reliability as a free open source Chrome extension for URL overrides and redirects. Users appreciate its straightforward functionality and ongoing maintenance. However, several reviews mention that Chrome has disabled the extension for some, leading to loss of functionality. Beginners find the settings somewhat hard to grasp, and there are requests for advanced features like regex support. Some users also report performance slowdowns on pages. Overall, it meets core needs well but faces challenges with Chrome policy changes and feature expansion.
