Requestly: Open Source HTTPs Debugging Proxy

Requestly is a powerful open-source HTTP debugging proxy Chrome extension that allows web developers to build, test, and debug web applications more efficiently. It includes features such as a mock server for creating fake API endpoints, an API client for testing API endpoints, HTTP rules for intercepting and modifying HTTP requests, and session recording for visual bug reporting and faster debugging. With Requestly, developers can work 10x faster in development, testing, bug reporting, and collaboration. Unlike other tools like Charles Proxy or Fiddler, Requestly doesn't require setting up a proxy in the browser, eliminating VPN issues.
