How did i not know about this. It is awesome. Powerful yet simple to use. I love it. My thanks to the developers.

★★★★★ Pete

Fantastic tool, great for debugging webservices, and the ability to automate responses is really handy. It's also got the things you'd expect; a detailed request inspector, and a request builder.
