Postman is a good tool that I've used for many years. It's currently open on my desktop. However I would never pay for their team collaboration features and I doubt I would pay much for the desktop client if they started charging for it. There are too many bizarre UI choices, too many missing features, and it's much too difficult to maintain scripted tests in their awful JSON based "collection" format. The good news is that they have lots of room for improvement and it's quite a bit better than some of the older alternatives like the absurdly awful SoapUI / ReadyAPI line of products.
