⚡ HTTP Interceptor for browsers

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.

🚀 What is Requestly

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.

✨ Features

👉 HTTP Rules (Intercept & Modify HTTPs Requests)

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

👉 API Client

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 (Create API Mocks in seconds)

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.

👉 Sessions

Collaborate with other teammates and get Requestly sessions that contain video, console logs, network logs, and env details for faster troubleshooting.
