Still Needs Valid JSON/XML Responses

Im still not sure why, but if the response is not a "valid" JSON/XML response, this program will output nothing.
This is fine for when developing against third-party APIs that are tested already.
However, if you are developing APIs and have some form of debug messages or exceptions thrown, this will not show them.
For this reason, I use GraphicalHttpClient (on the Mac App Store as well) more, because it shows all output, regardless of form.
Its a shame because the look/feel of Rested is really great, and Id like to use it as my primary tool.
Perhaps one day the developer will allow the displaying of non-conforming output.

Just my experience...
Since both Rested and GraphicalHttpClient are pretty cheap, Id recommend buying both and seeing what works best for you.

(Im not affiliated with either program, just trying to provide a good, honest comparison)
