Request Interceptor is a free Chrome extension developed by Vinay Kaparthi. It falls under the category of Browsers and specifically belongs to the Add-ons & Tools subcategory. This powerful extension allows users to intercept HTTP requests and add custom rules to modify request and response headers, block or redirect requests, and modify query parameters.

With Request Interceptor, users can easily build rules or conditions that, when met, enable them to redirect or block HTTP requests. This feature is particularly useful for developers and testers who need to simulate different scenarios during the development or testing phase. Additionally, the extension allows users to throttle the response of static resources, providing control over the speed at which these resources are loaded.

Another key feature of Request Interceptor is the ability to add, modify, or delete request and response HTTP headers. This allows users to customize the headers sent with each request or modify the headers received in the response. Moreover, the extension enables users to add, modify, or delete HTTP query parameters, providing flexibility in manipulating the data being sent or received.

Overall, Request Interceptor is a valuable tool for developers and testers who need precise control over HTTP requests and responses. With its intuitive interface and comprehensive set of features, it offers a convenient way to modify and control the behavior of web applications.
