PhantomJS is a headless browser. It's still running webkit, but it loads pages just like a regular browser and allows you to run custom JS scripts on pages, making it useful for QA and TDD. The only snag I've hit with PhantomJS is it starts to get buggy if you run it using a long-running script and intend to open several tabs often.
