I think the killer feature for these separate tools is usually that you can easily do a right click -> "copy as curl" in the network inspector, then import it in Postman/Paw and then tweak parameters / add headers there. This is not really possible in the browser network tools.

It seems pretty easy with Firefox - there's "Edit and resend" in the context menu of every request.

And then you accidentally refresh or close the tab and everything is gone. I usually use specific requests over many days if I'm reverse engineering something so having these available, sorted in folders for me is important. Of course for other uses cases it might be fine to have them live in the browser.

Se above. On MS Edge chromium you can enable to save the requests and even saved environments

I take that curl command to https://curlconverter.com

And get Python that I can start iterating on. They have lots of languages.

I used to use Postman but the clarity of the code is so much easier to see what’s happening vs postman imo.

On the on Microsoft Edge chromium you can can enable an "edit and resend" feature save the requests to "Collections" and create request environments.

I wonder if a such a feature can be added in Chrome/Firefox with an extension.
