How Requestly Helps Developers with
Local Development & Testing

Sync frontend-backend teams


Enable you, frontend developers, to develop & test your features independently of backend developers. With a simple toggle, build against actual/stubbed APIs.

Test your JS / APIs across environments

Environments Dependence

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, providing the freedom to test and validate changes in real-time.

Request Header, Payload & Responses

Override GraphQL API

Intercept, Modify & Mock GraphQL Query, Mutations & Response by applying additional targeting on operation name and query data.

Capture & Share HTTP Sessions


Easily capture HTTP sessions and share with developers. Requestly Sessions are more than just HAR logs. It contains mouse movements, network logs, console logs & other details.

QAs spend less time on bug reporting


Product Managers share feedback on sessions


Developers use sessions in pull requests

Create API Mocks in seconds

From Debug to Deploy: Developers Trust Requestly

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.

Carl Hand
Senior Software Engineer at Workday

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.

I’m a big fan of Requestly, and use it on a daily basis as a QA Engineer. It removes the need to use Charles Proxy often, which is always nice. I can just use Requestly directly in Chrome

Mike Mitchell
QA Engineer at URBN

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)

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’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.

Divyanshu Sharma
Full-stack Developer at ShortLoop

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.

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!

Dan Mindru
Founder of Shipixen

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.

Jose Browne
Senior Engineer at Reddit

App works as expected! Ran into some small issues while creating the rules but the support team was able to help and overcome those.

José Miguel Dias Fernandes
Development Lead at Vodafone

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.

Marius Ludick
Solutions Architect II at Amazon

Requestly is an amazing tool to get your development work less hassle. The product itself has evolved so much since day-1 and the company is really serious on helping their customer solves their problems. We had this nice session where they shared Requestly features and we were very impressed on its potential. A truly 5-star worthy.
