- Validate edge cases
- Stress-test applications
- Simulate backend responses
- Bypass backend complexities
- Mock Third-Party API Responses
Build frontend when the backend isn’t ready
Use the Modify Response rule to create mock APIs with custom responses and status codes. Easily disable these mocks when actual APIs become available.
Test for edge/Corner cases
Simulate diverse API edge cases (e.g., missing parameters, null values, incorrect data types) without modifying the backend. This ensures robust error handling in your code.
GraphQL support
GraphQL’s single-endpoint design can hinder targeted API modification. Requestly solves this with operation name filters, enabling precise response manipulation in GraphQL.

Loved by developers around the World
Developers around the world trust us to simplify debugging, speed up workflows, and make development more efficient.
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!
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 invaluable tool that helps us test, validate, and troubleshoot our features and client integrations.
Requestly helps us creating mock endpoints around back-end work that is still in development, allowing us to more easily work in parallel with our API teams without having to z.
I have used Requestly extensively in my work and for personal use and it has been a game changer in optimizing my workflow. The Requestly team are responsive to support requests and keeps adding more features. Because of this, this extension has become crucial to helping me perform my day-to-day tasks. For anyone who works heavily in development and testing around web-based environments, I would recommend that they try this extension.
Great tool and great support!
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)
Very simple to use and super useful! Great support too. Thank you!
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.
Requestly comes as a savior whenever the Adobe platform debugger shows a glitch in the launch library override. I used Requestly for redirect and mockup file server and it really helped me in dev and debugging. The interface is easy to use and creating a rule on one machine and accessing it from different machines makes it awesome.
Saves me tons of time in development, testing, and diagnostics. I'm not sure how I'd do my work efficiently without it.
Great functionality and amazing support. I ran into a problem with the Addin and the engineering team reached out to figure out a solution. They took the time to replicate the issue as well as provide alternative workarounds.
I highly recommend this extension, I work with software development and it helps me a lot in the tests I have to perform on the endpoints
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.
Great tool! I use the tool to easily inject the script of our app onto customer websites to use during sales demos so I can show Fullview running on their sites
Love using Requestly to swap versions of Adobe Launch from Prod to Staging and Dev. And also blocking various martech scripts to analyze their impacts on CWV(Core Web Vitals).
