I’ve been a Postman user for my entire developer career. I remember when it was just a simple Chrome extension that made pentesting APIs slightly less painful. Those were simpler times. Today, I find myself joining the growing exodus of developers abandoning these tools because they sell out.
I’ve taken to writing .http files which are runnable on a number of IDEs and plugins. I don’t need to know what anybody else is using to run them, they live with the code and I’m happy.
That said, I’ve seen people on QA do really cool end-to-end tests at load via very approachable scripting on Postman.
There’s lots of room for “to each their own” here.
