Bruno is great. I'm in the process of moving my team to it. Cli, gui, human readable files. They are hitting all the right points. And it's open source so I don't care if they close up later down the line. It can always be forked like insomnium. I do admit it is rough around the edges (bugs and a bunch of missing features) but there is a lot of momentum right now and devs are working hard. Not long before postman parity.
