 *   **Description:** Requestly is a versatile tool available as both a browser extension and a desktop app. Its origins lie in intercepting and modifying HTTP requests (e.g., redirecting URLs, modifying headers/responses, simulating network conditions), which is invaluable for frontend development and debugging. It has expanded to include a capable **API client**, allowing users to send HTTP(S) requests directly. It also features **API mocking**. This combination of interception, modification, mocking, and request sending in one tool makes it powerful, especially for web developers needing deep browser integration or comprehensive debugging capabilities. Its **free** tier offers significant functionality.
