A tool (like diff) to show the differences between 2 URLs, in particular including the query string broken down into an object structure. For a better description press the Demo button, its worth a 1000 words...!
I often find myself having to compare two URLs, usually with a query string hundreds of characters long and often with reordered parameters which make no functional difference but makes it very hard to compare. Hence this tool.
The only comparable tool I could find is url_diff (on Google's GitHub repo no less) but in Python.
Credits to URI.js and jsondiffpatch all I had to do was stick them together.
