I created Taffy because I was not happy with the amount of code it took to create REST API's with ColdFusion. I wanted something terse, something that used convention over configuration, and something that didn't require writing a bunch of boilerplate code. Nothing existed that filled that void, so I wrote it.
Version 1.2.0 was released on December 27th, 2012. (changelog)
