Question 1

Is this a full Postman replacement?

Accepted Answer

It covers the most common REST API testing needs: all HTTP methods (GET, POST, PUT, PATCH, DELETE, HEAD, OPTIONS), custom headers, request body, and response inspection with timing. For basic API testing and debugging, it works great right in your browser without installing anything.

Question 2

Are my requests sent from my browser?

Accepted Answer

Yes, all requests are made directly from your browser using the Fetch API. No data passes through our servers. Note that CORS policies on the target API may block some requests from the browser.

Question 3

Can I send JSON data in the request body?

Accepted Answer

Yes. Select POST, PUT, or PATCH as the method, set the Content-Type header to application/json, and enter your JSON payload in the body tab. The tool validates your JSON before sending.

Question 4

Does it save my request history?

Accepted Answer

Yes, your recent requests are saved in the current session so you can quickly re-run or compare responses. History is stored locally and never leaves your browser.
