Confusion regarding webkit and "chromium source"

[werfus]

The description of SRWare Iron states that it's "based on the free Sourcecode "Chromium." Is "the free Sourcecode "Chromium" the same code as WebKit?

[arflech]

The Chromium project is an open-source browser built on the Webkit engine (it also uses other projects not used by all Webkit-based browsers, like the V8 Javascript engine); nightly builds of Chromium are basically Chrome without the proprietary components (like the bundled Flash Player), and SRWare makes some changes to the Chromium source code (like disabling the RLZ identifier and implementing a primitive yet effective adblock.ini filter) to create Iron.
