punykit
PunyKit - it's a very simple webkit-based browser.
Rocket science it is not: PunyKit, a puny WebKit-based browser.
PunyKit is a browser I created in about an hour or so, maybe less. It is a QtWebKit centred application that displays the page in a "mobile browser similar" manner, and keeps that oh-so-useful WebInspector open in a separate window next to it.
What I'm aiming for is something that is as close to the iPhone simulator as possible, but with a web-inspector and (Yay!) works on machines which weren't made by the Apple corporation....
