Many, many years ago, I used Postman for the first time, way back when it was a Chrome plugin. As an iOS dev, it was amazing to be able to validate the requests I needed to make outside the context of my code to validate things worked. Until, one day, I wasn't seeing something iterate in the responses I was getting as I expected to. Many cmd+R presses later, I talked to the API team to check logs, and we found that Postman was caching what should have been independent requests. Easily blamed on Chrome at the time, but it was an undocumented and unexpected behavior by Postman, who really should have better handled making each request unique.

I didn't need another reason not to use Postman, but I'll take it. Shame on them for moving in shadows.
