Incredible Tool for API Testing & Interception! Requestly has been a game-changer for my workflow! As a developer, I often need to modify API requests, test different scenarios, and debug network calls. This extension makes it incredibly easy to intercept, modify, and mock requests without needing complex setups. What I love about Requestly: ✅ User-friendly Interface – Super intuitive and easy to navigate. ✅ Powerful Features – Modify requests, redirect URLs, block ads, and test APIs effortlessly. ✅ Time Saver – Eliminates the need for local proxies or backend changes. ✅ Works Seamlessly – Reliable and doesn’t slow down my browser. I've tried many similar tools, but nothing comes close to the flexibility and ease of use that Requestly offers. Highly recommended for developers, testers, and anyone dealing with APIs!
rubbish！doesn't works without internet! then how dare you called "Local-first Developer Tool"? ridiculous!
It isn't free. You must pay to use this extension.
Написано бесплатно можно делать 5 правил, но после обновления нельзя нечего делать без оплаты.
We have been using Requestly for HTTP Rules and Network inspector capabilities, which works great. We recently migrated from Postman to API Clients capability of Requestly. # Seamless migration for our 100+ postman collections / environments in single click. # Great support and diligence from team in building required features and incorporating feedback.
I’ve found Requestly to be an invaluable Chrome extension for development. It allows me to mock APIs, intercept requests, and test frontend changes even when the backend isn’t ready. The ability to modify headers, simulate delays, and inject scripts has made debugging and collaborating so much easier
Absolutely love the API Client feature! It’s like Postman, but better integrated into my daily workflow. Modifying API responses directly from the same tool I use for debugging is such a time-saver. Great job, Requestly team, for constantly innovating!
Super useful! Really like the new API Client feature, which kinda replaces Postman and Hoppscotch for me since I can easily do API testing as well as modify API responses.
My absolute favorite web debugging proxy and API client. I use it nearly every day for work to modify HTTP requests, test and mock API calls, inject JS snippets into sites, etc. The Requestly team is incredible — I once submitted a bug report and it was closed out within an hour. Also just kind, passionate people. I can't recommend Requestly enough.
The best solution for android phones and tablets.
