WebKit

WebKit is a powerful, multi-platform HTML engine used in open source and commercial/proprietary products alike. WebKitGTK is the port of WebKit built on GTK and integrated into the GNOME developer platform. WebKitGTK is developed upstream as part of the main WebKit project, so it's always up to date with the latest HTML5 features.

WebKitGTK makes it easy to add web functionality to your application, or to use HTML5 and associated technologies to create dynamic user interfaces quickly.
