Edge’s favorite Open-Source DevTool of 2024! Named one of the best Edge extensions to Modify HTTP Requests by the Edge team & rated 5 stars by 200,000+ users. Best alternative to Charles Proxy, Fiddler and ModHeader that works directly in Edge with beautiful, modern UI and team collaboration features. Top Use Cases → Test JavaScript changes directly on your production site without code changes. → Use Redirect Rule to load scripts from local or staging environment on production sites. → Modify and Mock API Request payload, Response body & Status Code. → Override GraphQL Requests 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.
