Fork (software development) in the context of MySQL

Google Chrome is a cross-platform web browser developed by Google. It was first released in 2008 for Microsoft Windows, built with free software components from Apple WebKit and Mozilla Firefox. Versions were later released for Linux, macOS, iOS, iPadOS, and also for Android, where it is the default browser. The browser is also the main component of ChromeOS, on which it serves as the platform for web applications.

Most of Chrome's source code comes from Google's free and open-source software project known as Chromium, but Chrome is licensed as proprietary freeware. WebKit was the original rendering engine, but Google eventually forked it to create the Blink engine; all Chrome variants except iOS used Blink as of 2017.

Safari is a web browser developed by Apple. It is built into several of Apple's operating systems, including macOS, iOS, iPadOS, and visionOS, and uses Apple's open-source browser engine WebKit, which was derived from KHTML.

Safari was introduced in an update to Mac OS X Jaguar in January 2003, and made the default web browser with the release of Mac OS X Panther that same year. It has been included with the iPhone since the first-generation iPhone in 2007. At that time, Safari was the fastest browser on the Mac. Between 2007 and 2012, Apple maintained a Windows version, but abandoned it due to low market share. In 2010, Safari 5 introduced a reader mode, extensions, and developer tools. Safari 11, released in 2017, added Intelligent Tracking Prevention, which uses artificial intelligence to block web tracking. Safari 13 added support for Apple Pay, and authentication with FIDO2 security keys. Its user interface was redesigned in Safari 15, Safari 18, and Safari 26.

WebKit is a browser engine primarily used in Apple's Safari web browser, as well as all web browsers on iOS and iPadOS. WebKit is also used by the PlayStation consoles starting with the PS3, the Tizen mobile operating systems, the Amazon Kindle e-book reader, Nintendo consoles starting with the 3DS Internet Browser, GNOME Web, and the discontinued BlackBerry Browser.

WebKit started as a fork of the KHTML and KJS libraries from KDE, and has since been further developed by KDE contributors, Apple, Google, Nokia, Bitstream, BlackBerry, Sony, Igalia, and others. WebKit supports macOS, Windows, Linux, and various other Unix-like operating systems. On April 3, 2013, Google announced that it had forked WebCore, a component of WebKit, to be used in future versions of Google Chrome under the name Blink. Since version 15 in May 2013, Opera web browser has dropped its own Presto layout engine in favor of WebKit as implemented by Google in the Chromium project.

Blink is a browser engine developed as part of the free and open-source Chromium project. Blink is by far the most-used browser engine, due to the market share dominance of Google Chrome and the fact that many other browsers are based on the Chromium code.

To create Chrome, Google initially chose to use Apple's WebKit engine. However, Google needed to make substantial changes to its code to support Chrome's novel multi-process browser architecture. Over the course of several years, the divergence from Apple's version increased, so Google decided to officially fork its version as Blink in 2013.

OpenBSD is a security-focused, free software, Unix-like operating system based on the Berkeley Software Distribution (BSD). Theo de Raadt created OpenBSD in 1995 by forking NetBSD 1.0. The OpenBSD project emphasizes portability, standardization, correctness, proactive security, and integrated cryptography.

The OpenBSD project maintains portable versions of many subsystems as packages for other operating systems. Because of the project's preferred BSD license, which allows binary redistributions without the source code, many components are reused in proprietary and corporate-sponsored software projects. The firewall code in Apple's macOS is based on OpenBSD's PF firewall code, Android's Bionic C standard library is based on OpenBSD code, LLVM uses OpenBSD's regular expression library, and Windows 10 uses OpenSSH (OpenBSD Secure Shell) with LibreSSL.

NetBSD is a free and open-source Unix-like operating system based on the Berkeley Software Distribution (BSD). It was the first open-source BSD descendant officially released after 386BSD was forked. It continues to be actively developed and is available for many platforms, including servers, desktops, handheld devices, and embedded systems.

The NetBSD project focuses on code clarity, careful design, and portability across many computer architectures. Its source code is publicly available and permissively licensed.

The iPad is a brand of tablet computers developed and marketed by Apple that run the company's mobile operating systems iOS and later iPadOS. The first-generation iPad was introduced on January 27, 2010. Since then, the iPad product line has been expanded to include the smaller iPad Mini, the lighter and thinner iPad Air, and the flagship iPad Pro models. As of 2022, over 670 million iPads have been sold, making Apple the largest vendor of tablet computers. Due to its popularity, the term "iPad" is sometimes used as a generic name for tablet computers.

The iPhone's iOS operating system (OS) was initially used for the iPad, but in September 2019, its OS was switched to a fork of iOS called iPadOS that has better support for the device's hardware and a user interface tailored to the tablets' larger screens. Since then, major versions of iPadOS have been released annually. The iPad's App Store is subject to application and content approval. Many older devices are susceptible to jailbreaking, which circumvents these restrictions.

The Open Handset Alliance (OHA) was a consortium led by Google that develops the Android mobile operating system. Its member firms included HTC, Sony, Dell, Intel, Motorola, Qualcomm, Texas Instruments, Samsung Electronics, LG Electronics (formerly), T-Mobile, Nvidia, and Wind River Systems.

The OHA was established on November 5, 2007, with 34 members, including mobile handset makers, application developers, some mobile network operators and chip makers. As part of its efforts to promote a unified Android platform, OHA members are contractually forbidden from producing devices that are based on competing forks of Android. While not officially stated, the alliance has remained dormant, with many OHA partners having moved out of the smartphone market.

Media Player Classic (MPC) and its derivatives are a family of free and open-source media players for 32-bit and 64-bit versions of the Microsoft Windows operating system. Focusing on compactness and customizability, Media Player Classic mimics the simplistic look and feel of Windows Media Player 6.4, but provide most options and features available in modern media players. The original MPC stopped development in 2006 after which it was forked into two new projects: Media Player Classic - Home Cinema (MPC-HC) and Media Player Classic - Black Edition (MPC-BE), which are now principally maintained by the community at the Doom9 forum.

The active fork Media Player Classic - Home Cinema (MPC-HC) is maintaned by "clsid2" (same developer known as clsid responsible for MPC 6.4.9.1), and Media Player Classic - Black Edition (MPC-BE) by "aleksoid". Variations of the original MPC and its forks are standard media players in the K-Lite Codec Pack and the Combined Community Codec Pack.

LibreOffice Writer is the free and open-source word processor and desktop publishing component of the LibreOffice suite and is a fork of OpenOffice.org Writer. Writer is a word processor similar to Microsoft Word and Corel's WordPerfect with many similar features, and file format compatibility.

LibreOffice Writer is released under the Mozilla Public License v2.0.

OpenOffice.org is an open-source office productivity software suite. It originated from the proprietary StarOffice, developed by Star Division, which was acquired by Sun Microsystems in 1999. Sun open-sourced the software in July 2000 as a free alternative to Microsoft Office, and released OpenOffice.org version 1.0 on 1 May 2002. Latest version 4.1.16 in November 2025 is a security update.

Following Sun's acquisition by Oracle Corporation, development of OpenOffice.org slowed and eventually ended. In 2011, Oracle donated the project to the Apache Software Foundation, which continues it as Apache OpenOffice,, with the most-recent version being 4.1.16, released on November 10, 2025. A fork of OpenOffice, LibreOffice, was created in 2010 by members of the OpenOffice.org community.
