One nice thing about it is only the builds are licensed. If you build from source it is MIT.

Great job putting the list together.

I think https://httpie.io is also in the category (I have only used it in CLI form, long back. My use cases don't need anything more than curl)

+1 for Yaak, I've used it for over a year for work and personal projects. It is stable and fast (also the dev behind it has the first name as me, so I'm a bit biased towards other Gregs!).
