🚀 Chrome’s favorite Open-Source DevTool of 2024! Named one of the best Chrome extensions to Modify HTTP Requests by the Google Chrome team.

❤️ & Used by over 230000+ web developers in 15000+ organizations. Github Repo - https://github.com/requestly/requestly/

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

🌟 Top Use Cases → Test JavaScript changes directly on your production site without code changes. → Use the Redirect Rule to load scripts from local or staging environments on production sites. → Modify and Mock API Request payload, Response body, & Status Code. → Override GraphQL Requests 📌 https://requestly.com/blog/what-is-requestly

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.

This extension made my browser unbelievably slow without warning, I have plenty of ram yet when this is installed. The browser becomes slow and as soon as I remove this. The browser is fixed and fast again

Love using Requestly to swap version of Adobe Launch from Prod to Staging and Dev. And also blocking various martech scripts to analyze their impacts on CWV.

Great tool! I use the tool to easily inject the script of our app onto customer websites to use during sales demos so I can show Fullview running on their sites
