I’ve been looking for an alternative to postman that isn’t so insanely geared to monetization. I feel postman compromises it’s entire UX to force a simple offline tool to be cloud based.
After having used postman for sometime, I realized it favors mouse click based workflow and is very resource heavy. I have switched to emacs verb[1] package and combined with some custom function for env (staging/local) management and org-roam for file management, it's much more comfortable to use. I don't have to learn a new set of shortcuts and can use all the other emacs features.
