Great questions:

1) the diff is really simple, line by line and text based. I'm just using this really awesome library to do it: https://github.com/kpdecker/jsdiff The JSON is just being pretty printed to be able to do a text diff in a meaningful way.

2) Yes, I do, and thanks for the suggestions! But I just wanted to go with the minimal version first and see if people found it useful.

I didn't know about Runscope's diffing feature. Btw, I'm using a HTTPBin for the sample requests, which is a Runscope project as far as I know :)
