I have a blood feud with Postman because, for years, every time an update came out it just got worse. I got to the point where I'd only update when I got a new work computer or had to for some specific feature (very rare)... that was maybe every two years.
Around 2023 (I think) I had to do an update and, after the update, it helpfully locked my dozens of collections and hundreds of LOCALLY saved requests behind a "you must create an account" barrier. I was fucking pissed, still am.
They did provide access to an "export" functionality but it wasn't easy to find and didn't seem to be documented. I found out about it with a web search where everyone was complaining about the tomfuckery and somebody offered that helpful bit of info.
Exported, tried a few other clients, settled on Bruno like a few other comments say. The postman export imported into Bruno just fine. Hoppscotch seemed pretty good too but I don't think it had Environments at the time. At least I remember there being something about environment configs where Bruno was better.
Fuck postman forever. https://www.usebruno.com/
