- API Integration Made Easy
- Team Workspace for teams/projects
Reduce
Environments Dependence
Test your JS / APIs across environments
Redirect HTTP requests(API Calls/Files) effortlessly from one environment to another. Helps you in testing locally running code – scripts or APIs directly on staging/production sites. Environments no longer bind you.

Great tool and great support!
Absolutely insane level of customisation and flexibility. Used this on a number of different use cases and love it. Works great and I found the UX fantastic. Nice job!
As a QA engineer, I found this extension to be a great tool for screen recording and network monitoring. Its user-friendly interface, robust features, and seamless integration make it an essential companion for thorough testing. Highly recommended for QA teams looking to enhance their testing processes.
Requestly’s browser extension is remarkably easy to use. As a full-stack developer, I often need to test data-intensive UI for edge cases and performance. Using Requestly I can do it very easily by mocking network requests, without needing code changes or database seeding.
Modifying requests and/or responses is the killer feature area for me. Redirect JS in prod, generate mocks, modify headers, map local, map remote, SessionReplay, Load a local JS bundle, override scripts, etc. etc. etc. – TOTALLY worth it and very useful.
Just loved the way Requestly saved several person hours for our dev team by allowing us to redirect and intercept requests. The simple yet efficient rules allowed us to seamlessly redirect requests from a single staging front-end server to local backend servers. This meant that our devs didn’t need to build or run the front-end server locally when focusing on backend tasks.
Awesome tool. I use it almost daily for my projects to modify request body, headers, etc. Would recommend it to every frontend developer out there. Thank me later 🙂 (Case Study)
Requestly not just made it easier for us to develop, test & debug our code on our customer sites but also helped us do engaging product demos to our prospective clients.
Does exactly what we need it to for testing new scripts. Also allows our sales teams to get easy access to Staging versions of our products. Support from Requestly is very strong as well.
An essential tool for any frontend developer. I would be far less efficient if it did not exist and not only that, their level of support is stellar and they’re always improving and adding more features too!
Requestly is awesome. I used to use Charles proxy in my day-to-day work but it always messed with my wifi. I haven’t had any issues with Requestly. Requestly’s UI is an amazing tool and great to work in.
Very simple to use and super useful! Great support too. Thank you!
