⚡ HTTP Interceptor for browsers </h2>
**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.
