I actually wasn't aware of it being open source at all, thanks. It's not mentioned anywhere on their page, gives me a bit more confidence :)

I still like Insomnia too.
I don't know what licence Postman uses. A quick search on GitHub didn't turn up the source of the app on the Postman Labs page. Insomnia is MIT [0], so it could still be forked if Kong got decided to stop supporting the free version.
