As someone who works on large-scale enterprise apps, this extension has been a lifesaver. It's super quick, lightweight, and does everything I need—GET, POST, headers, auth, you name it. I love that it runs right in the browser and keeps everything local. No switching tools, no fuss—just clean, fast API testing. Can’t recommend it enough!

This extension is very helpful. It works inside the browser, so I don’t need to open Postman at all. I use it to test API calls and to automate some of my daily jobs, it’s easy to add headers and change settings. It’s great for anyone who works with APIs, even if you’re just learning.

I’ve tried many tools, but this Chrome extension stands out. It’s fast, secure, and incredibly easy to use — I can test any API directly in the browser with full control over headers, auth, and payloads. No need for external apps, and everything runs locally, so my data stays safe. If you work with APIs, you need this. It’s now part of my daily workflow — and I recommend it to every developer I know.
