WebCore is a layout, DOM and render library for CSS and SVG that has been split off from KHTML. It has passed the Acid2 test and, since September 2008, the development versions have also been the first HTML rendering engine to have the Acid3 test, with rendering that is precise pixel by pixel and fluid on reference hardware.
In 2003 the project was officially announced and the sources released according to the licenses of the KHTML and KJS projects. However, the way in which the changed code was passed on and published met with criticism: The KDE developers accused Apple of only providing changes in large, difficult-to-understand packages; this makes code adoption difficult, causing the projects to become more and more distant.
In June 2005, Apple's Dave Hyatt promised to open the development process and provide all of the WebKit's sources in a CVS tree. As a result, Nokia announced a browser based on this, and Adobe announced that the Adobe Integrated Runtime would also integrate WebKit.
Until April 2013, Google was involved in the further development of WebKit. Since then, Google has been using the WebKit Fork Blink for its Chrome web browser .
WebKit is part of the macOS operating system from version 10.3 . It is mainly used in the Safari browser, but also in the help function and in the HTML display in TextEdit and Mail .
Other browsers are also based on WebKit, for example Google Chrome (up to version 27), Yandex.Browser , SRWare Iron , OmniWeb , Shiira , iCab , Midori (with Midori, however, in the variant WebKitGTK + , since Midori is written in C ) and Roccat . The browser Lunascape , which uses several rendering engines, can also use WebKit. The third version of the Maxthon browser also uses it. In 2013 Opera wanted to switch to WebKit as the browser engine in order to catch up with Google Chrome and save further development effort in Presto. However, after it became known that Google would develop a fork of WebKit called Blink and use it in Chrome, Opera decided to follow this decision and to use Blink as the browser engine in the future.
WebKit also plays a major role in the browsers of mobile devices: ABrowse has been using it as a basis for the Syllable operating system since July 2007 instead of the previously used KHTML. The free smartphone operating system Openmoko and Android , Google's software project for mobile systems, use WebKit. WebKit is also an integral part of the HP webOS (formerly Palm) mobile operating system for smartphones and tablets and is used to display the user interface. There are also iPhone / iPodTouch / iPad from Apple and Nokia's S60 series. In August 2010, RIM announced the use of WebKit.
With its Origyn Web Browser (OWB), the French company Pleyo offers a WebKit-based browser under BSD or LGPL license for entertainment electronics (e.g. mobile devices, set-top boxes) such as the Nokia N800 or AmigaOS .
The programs of the free desktop environment Gnome that display HTML content , including the standard Epiphany browser , have also been converted to WebKit from version 2.28. Numerous GTK-based programs, some of which also belong to the GNOME project, will also be converted.
Since the KDE Software Compilation 4.5 it is possible to install WebKit from the Extra Gear sources and select Konqueror as an alternative to KHTML in the standard browser . The rewritten slim browser Rekonq is built directly on top of WebKit. The Kubuntu distribution has been using Rekonq as the standard browser since Maverick Meerkat 10.10. In the meantime, the development of Rekonq has been stopped. As an alternative, there is Otter, which is based on a fork of QtWebkit from Annulen, and Liri and Qupzilla, which use QtWebEngine, a Qt port from Chromes Blink.
Since its major interface update in 2010, the computer game distribution platform Steam has used WebKit as its HTML rendering engine.
The command line tool wkhtmltopdf uses WebKit to render HTML documents and then save them as PDF files.
