🚀 Chrome’s favorite Open-Source DevTool of 2024! The best Chrome extension to Test & Mock API Requests.

❤️ & Used by over 250,000+ web developers in 15000+ organizations. Github Repo - https://github.com/requestly/requestly/

Open-Source & Powerful Combination of Postman & Charles Proxy replacing multiple tools like Fiddler, Resource Override, Proxyman and ModHeader from developers toolset. Requestly works directly in Chrome with beautiful, modern UI and team collaboration features.

🌟 Top Use Cases → Mock API Responses to build frontend when backend isn't ready → 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 tool is amazing. It is very easy to set up and it has made the lives of software engineers and QA testers that little bit easier. My main usage of the extension is to view the app version (urls) of the Telegrap App. Definitely recommend.

I initially had a little trouble and uninstalled, I was given a quick survey upon uninstall and they actually offered a customer support call over zoom/google meet the next day. I honestly had doubts it was real but the VP showed up, solved my difficult issue and I'm extremely impressed to say the least! 5 stars fully earned and I will be pushing for my team to embrace this tool as there are other excellent uses it provides beyond my issue as well.

https://app.requestly.io is not openning. Extension is not working without that. Waste of my time
