Tests you can generate
Status code checks
Verify exact status codes or status categories (2xx, 4xx, 5xx) with precise, readable assertions. Ensure your API behaves correctly under both success and error scenarios.
JSON validity & structure
Automatically confirm that the response contains valid JSON. Catch malformed responses before they break client-side logic.
Schema validation (AJV)
Validate entire JSON structures using auto-generated AJV schemas. Guarantee consistent API contracts across every environment.
Field-level assertions
Assert existence and correctness of specific fields in the response. Perfect for validating key data like id, email, status, and nested objects.
Header assertions
Check presence and accuracy of essential headers like Content-Type or Authorization. Ensure your API communicates the right metadata every time.
Array and list validations
Confirm array lengths, ensure items match expected types, and validate list contents. Ideal for endpoints returning collections, lists, or paginated data.

Loved by developers around the World
Developers around the world trust us to simplify debugging, speed up workflows, and make development more efficient.
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!
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.
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.
Requestly is an incredibly useful tool for developers working on a large team with multiple staging envs, or numerous app endpoints for various APIs in a local environment. The Sessions feature is especially useful for documenting solutions or sharing with others since it captures the relevant network traffic, and screen recording enables others to easily reproduce. Requestly combines all the power of complicated tools like Charles Proxy and Postman in one app/chrome extension. I highly recommend giving it a try if you haven't already–it will make your dev work so much easier. (Summarized)
Requestly is user-friendly, brilliant and easy-to-use. I use it on an daily basis and it makes my work easier. After using other tools like Charles - Requestly is a nice new breath of air that I highly vouch for. Apart from the tool being amazing - the support from the Requestly team is phenomenal with them always going above and beyond for their clients.
This is by far the best tool for managing request headers! Plus the developers are very active meaning you'll get help if you're ever stuck or need help solving a problem. I use it daily and couldn't be happier.
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 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.
