# REDIRECT WebKit # WebCore

WebKit's WebCore and JavaScriptCore components are available under the GNU Lesser General Public License, and the rest of WebKit is available under a BSD-form license.

On June 7, 2005, Safari developer Dave Hyatt announced on his weblog that Apple was open-sourcing WebKit ( previously, only WebCore and JavaScriptCore were open source ) and opening up access to WebKit's CVS tree and the bug Database tool.

WebKit's JavaScriptCore and WebCore components are available under the GNU Lesser General Public License, while the rest of WebKit is available under a BSD-style license.

WebCore is a layout, rendering, and Document Object Model ( DOM ) library for HTML and SVG, developed by the WebKit project.

The WebKit framework wraps WebCore and JavaScriptCore, providing an Objective-C application programming interface to the C ++- based WebCore rendering engine and JavaScriptCore script engine, allowing it to be easily referenced by applications based on the Cocoa API ; later versions also include a cross-platform C ++ platform abstraction, and various ports provide additional APIs.

The latest version of Series 40, called Series 40 6th Edition, introduced a new browser based on the WebKit open source components WebCore and JavaScriptCore.

* Browsers based on WebKit ( such as Apple's Safari, Google Chrome, and The Omni Group's OmniWeb ) have had incomplete support for the SVG 1. 1 Full specification since 2006.

It was based on Apple's internal fork of the KHTML rendering engine, called WebKit.

It includes a version of Safari based on the same WebKit rendering engine as the desktop version, but with a modified feature set better suited for a mobile device.

For Haiku there is a successor for NetPositive, based on WebKit, called WebPositive.

It supports many web browsers including Firefox, Mozilla Application Suite, and other Netscape plug-in based browsers ; Safari, Chrome, and other WebKit based browsers ; and Opera.

The week after Hyatt's announcement of WebKit's open-sourcing, Nokia announced that it had ported WebKit to the Symbian operating system and was developing a browser based on WebKit for mobile phones running S60.

The Android mobile phone platform uses WebKit as the basis of its web browser and the Palm Pre, announced January 2009, has an interface based on WebKit.

The Amazon Kindle 3 includes an experimental WebKit based browser.

Both these browsers are based on WebKit and run on most mobile operating systems including Linux, Android, Unix, and Windows CE.

* NetFront Browser NX for Internet Appliances ( based on WebKit )

Gecko is the third most-common layout engine on the World Wide Web, after Trident ( used by Internet Explorer for Windows since version 4 ) and WebKit ( used by Safari and Google Chrome ), and followed by Presto ( used by Opera ).

iTunes uses WebKit to render these pages on the screen.

As the backend development advanced, on the Epiphany team announced that it would stop using the Gecko rendering engine and proceed using just WebKit.

Avant Browser 2012 Ultimate edition ( build 3 released on October 25, 2011 ) added the Gecko layout engine ( the rendering engine used by Mozilla Firefox ), and the most recent release ( build 168 released on April 6, 2012 ) also included the WebKit layout engine ( the rendering engine used by Google Chrome ), making Avant Browser a three-engine browser.

The WebKit project was started within Apple by Don Melton on 25 June 2001 as a fork of KHTML and KJS.

WebKit is used as the rendering engine within Safari on Windows, Mac OS X and iOS.

Other applications on Mac OS X make use of WebKit, such as Apple's e-mail client Mail and the 2008 version of Microsoft's Entourage personal information manager, both of which make use of WebKit to render e-mail messages with HTML content.

New web browsers have been built around WebKit such as the S60 browser on Symbian mobile phones, Blackberry Browser ( ver 6. 0 +), Midori, Shiira, Chrome browser, Uzbl, Maxthon 3, xxxterm, the Android Web browser, and the browser used in PlayStation 3 system software from version 4. 10.

* WebKit-based, such as Safari ( including iOS ), Android's browser, Kindle 4's browser, Epiphany and Midori ( WebKit is a derivative of Konqueror's KHTML engine, but Mac OS X does not share the KIO architecture so the implementations are different ), and Webkit / Chromium-based, such as Chrome

KDE's open-source KHTML engine is used in KDE's Konqueror web browser and was the basis for WebKit, the rendering engine in Apple's Safari and Google's Chrome web browsers, which is now the most widely used browser engine according to StatCounter.

This was one of the reasons why Apple forked KHTML to create the WebKit engine ( which is now used in several web browsers, including Safari and Google Chrome ) over the XPCOM-based Gecko rendering engine for their web browser.

A forked version of KHTML called WebKit is used by several web browsers, among them Safari and Google Chrome.

Apple publishes the source code for their fork of the KHTML engine, called WebKit.

The code that would become WebKit began in 1998 as the KDE ’ s HTML layout engine KHTML and KDE's JavaScript engine ( KJS ).

Many KHTML developers have become reviewers and submitters for WebKit SVN repository.

In July 2007, the Ars Technica website published an article reporting that the KDE team would move from KHTML to WebKit.

Instead, after several years of integration, KDE Development Platform version 4. 5. 0 was released in August 2010 with support for both WebKit and KHTML, and development of KHTML continues.

However most of the layout engines work perfectly well with this construct, some examples are: KHTML ( Konqueror ), WebKit ( Safari and Google Chrome ) and Gecko ( Mozilla Firefox )

For example Carakan is used with Presto ; Nitro with WebKit ; SpiderMonkey with Gecko ; KJS with KHTML ; Rhino by default has no layout engine.
