Requestly is not just one of the best — it’s the best HTTP interceptor for network calls that I’ve found. It’s incredibly helpful for testing purposes: modifying API responses, redirecting requests, and simulating different scenarios is simple and reliable. Great job!
Requestly is an exceptionally useful API and network debugging tool that significantly improves developer productivity. Its ability to intercept, modify, redirect, and mock API requests in real time makes it an essential companion for frontend and full‑stack development. What stands out most is the ease of use. The interface is clean, intuitive, and well-organized, allowing even first-time users to start creating rules and mocking APIs with minimal learning curve. Features like request/response modification, API mocking, HTTP header manipulation, and endpoint redirection are incredibly helpful for testing edge cases, debugging issues, and working independently of backend readiness. Requestly also excels in team collaboration. Shared rules and environments make it easier to maintain consistency across development and QA teams. This is especially valuable in fast-paced agile environments where backend APIs frequently change. Performance-wise, the app is lightweight and reliable, with minimal impact on browser performance. The browser extension integrates smoothly with Chrome and other Chromium-based browsers, and the desktop app adds flexibility for more advanced use cases. Overall, Requestly is a powerful, well-thought-out tool that saves time, reduces dependencies, and streamlines API testing and debugging. It’s highly recommended for developers, QA engineers, and anyone dealing with APIs on a regular basis.
very helpful tool
As a QA, this tool helps me greatly in mocking API response without touching much in code base
