Contrary to popular belief, the browser can perform POSTs as well as GETs.

An inline form on the webpage that POSTs the result is not a "webpage/separate tool". Option 2 would be to use the browser's dev console.

You need a webpage to have an inline form, which you need to create somehow. Compare that to just opening a new tab and type in an URL.

The dev console is a separate tool. And I'm still sure it is much quicker and easier to open a new tab and type in an URL, than to do a POST with dev console.
