Can't believe we almost switched to that to get away from Postman. At this point, I'd rather have a text file full of curl commands, because httpie looks about ready to spring an Enterprise tier as well.
And what is wrong with (a well-structured hierarchy of folders containing) text files (i.e. scripts) full of curl commands? You can also track and version them in git, automate them, etc.
Genuinely asking of course, because I never got the "point" of Postman vs. curl, except maybe for non-technical people.
