I can't speak to Postman specifically, because I barely use it enough for it to make a difference. But in a more general sense, I tend to prefer <thing> in a browser over <thing> but in its own window. It means one fewer program filling my taskbar.

I can see that, but for me it's more:

- Dork with code/ routes in one window and/or dorking around with the front end code.

- Postman (the stand alone program) in another window to check what the return from the server really is or what the API is doing now.

So I've got it on it's on dedicated space (not all the time but often enough).

I very rarely have only a single browser window, and I'm not coding in a browser anyway, so that's not actually a huge factor in the decision. I agree with using windows to easily switch between tweak and test.
