Requestly was built to save developers time by intercepting and modifying HTTP Requests. It has now developed into an open-source alternative to Charles Proxy and Telerik Fiddler that works directly in browsers without VPN and proxy Issues. It is used by more than 200,000+ front-end developers and 11,000+ companies worldwide.
Requestly is an Open-Source platform for front-end developers with essential tooling & integrations that helps them write, test & debug their code 10x faster. Requestly reduces dependency on backend devs and environments for development & testing needs.
Using Requestly, devs can create mock, test, validate & override API responses, modify request & response headers, set up redirects (Map local, Map remote), and use Requestly sessions for faster debugging.
Intercept & Modify HTTPs requests & responses from browsers & mobile apps.
- 👉 Use the browser extension for capturing & modifying traffic from browsers
- 👉 Use the desktop app for capturing & modifying traffic from mobile apps & other desktop apps.
Different Modifications supported
- Rewriting URLs (Map Local & Map Remote) e.g.
- Change Hostname, QueryParams, etc in the URL
- Redirect traffic from one environment to another (e.g. production to dev)
- Swap Tag Manager scripts from production to staging/dev environment
- Modify HTTP Request & Response Headers
- Modify API Request & Response body
- Throttles & Blocking of Requests
- Inject scripts on web pages
Requestly offers a minimal, lightweight API client that works directly in the browser. It can help you
- Import cURL requests,
- Send new requests, and
- Quickly test API responses.
- Integration with Mock Server to clone an API endpoint with the same response
- Integration with Modify Response Rule to override the response body
Mock Server helps you quickly create API mocks. Especially helpful when APIs don't exist and you have to build a feature, just define the response you need and get an endpoint to be used in your code.
Collaborate with other teammates and get Requestly sessions that contain video, console logs, network logs, and env details for faster troubleshooting.
