I have recently tried Bruno, but it lacked some basic UI features I use regularly, like file picker UI for uploading a multipart file.
I also gave Recipe Ul a look, but I did not see an option to switch environments. (Haven't installed it and tried it, just went through the docs)
So I settled on Hopsscotch. Though their desktop UI is still in alpha, it looked good to me.
No, I am trying out their desktop app.
