A great time saver
I do implement and test REST APIs quite regularly and tested quite some RESTClients so far, and yes you can do most of the features of Paw using any scripting language and/or cURL, but I find Paw way more comfortable.
On big advantage of Paw over cURL is, that non-technical people seem to get the results much easier compared to showing them cURL results.
