Actually, there is something wrong with Postman. It didn't affect the Chrome version but the standalone has a serious bug where it just completely ignores your hosts file. There's been a Github issue for it for over a year but they haven't bothered to fix it.
Personally, I prefer Postman but because of that bug it's basically useless for me.
