Best alternative to Charles Proxy, Fiddler, and ModHeader that works directly in Chrome with beautiful, modern UI and team collaboration features.

Unlike Charles Proxy & Fiddler, Requestly doesn’t set up a proxy in your browser, and hence, developers don’t face VPN issues or lags while using it. Requestly leverages Chrome Extension APIs under the hood to hit API endpoints and intercept & modify requests.

→ Define Custom Response for your APIs requested by XHR/fetch
