I wanna say insomnia but I don’t know if it’s FOSS. It’s made by a company named Kong as a side project.

Curl.

It's foss but got purchased by Kong and started becoming a bit too much of a product for my liking, it has a fork called insomnium that keeps development where it used to be before but it's no longer maintained sadly

Bruno is pretty good

Still better than Postman.

import requests

theUrl = r'https://threatbutt.com/map/'

response = requests.get(theUrl)

print(response.text)

Might as well use curl at that point

Thunderclient is great if you use vscode

Think I used this for a little while. It was pretty much a slightly better Postman, back when Postman itself was less annoying.

Frustratingly, at some point I opened Insomnia and it randomly lost all my requests/history. That soured me on it. Then when I tried it again a couple years later, it had that bad 'freemium' feel, even if it is still FOSS.

This is proprietary

Total feelings of superiority: immeasurable.

Facts!

Hopscotch is nice. I'd like that feeling of superiority from using solely curl, tho
