This API Client Is Amazing! (HTTP Interceptor, API Mocking, Redirect, Modify Response)

Requestly is an API development tool that helps developers intercept, mock, and modify HTTP requests during frontend development. It allows testing with non-existent API endpoints, simulating different response states, modifying headers, adding delays, and redirecting requests. The tool works as both a Chrome extension and desktop application, enabling developers to experiment with UI components before backend APIs are ready, test error states, and debug network issues without modifying actual code.
