Is there a handy GUI for REST manual services testing?

Question

While developing a REST service I want to be able to manually submit some data (e.g. by PUT or POST method) to a specific URL and see the response. The only tool I know is SoapUI, which is not only a commercial product, but a bit overcomplicated while my task is so simple. There is a question about SoapUI alternatives, but all the discussion there is about SOAP services, while what I need is just some REST :-) Any ideas? I know I can write such a tool myself pretty easily, but I'd prefer not to reinvent a bicycle if there is one.

UPDATE: Mark Cidade's answer is ok, but I'd wish the tool could run on Linux too...

UPDATE 2: The solution of my choice came to be HttpRequester Firefox extension.

Answer 1

There is yet another free handy application called Postman which will let you do this. It was initially launched as a Chrome plugin and since then is available on the Mac.

I use the Chrome plugin extensively on Windows, Linux and Mac. What I find most useful is the fact that, when signed in, all your requests can be synced across all machines. I use the Mac at the office and when I get home, I pick up where I left of on a Windows machine.

Answer 2

I have just discovered and installed RESTClient, which is a Firefox add-on (it's ideal for me as I do most development on FF, both on Windows and Linux). No idea if it's any good yet. :)

EDIT: I've started it using extensively since, and it's very good, it really gives back a lot of data about the response and the request.
