Have you ever wanted to dig into your web pages on your mobile devices and don't have the capabilities to view source code or poke around? Snoopy is a bookmarklet for snooping on web pages. It's intended for use on mobile browsers like the iPod, iPhone, and iPad Mobile Safari where you can't view-source to poke around under the hood of sites to see how they're built.
Using the bookmarklet will give you an overlay that shows you information such as what Doctype the page has, what JS libraries are used in the page, what analytics, etc. It also gives you the ability to view the raw and/or generated source of the page.
