Comparison Of Version-control Software
The following tables describe attributes of notable version control and software configuration management (SCM) systems that can be used to compare and contrast the various systems. For SCM software not suitable for source code, see Comparison of open-source configuration management software. General information The following table contains relatively general attributes of version-control software systems, including: *Repository model, the relationship between copies of the source code repository ** Client–server, users access a master repository via a client; typically, their local machines hold only a working copy of a project tree. Changes in one working copy must be committed to the master repository before they are propagated to other users. ** Distributed, repositories act as peers, and users typically have a local repository with version history available, in addition to their working copies. *Concurrency model, how changes to the working copy are managed to p ...

Version Control
Version control (also known as revision control, source control, and source code management) is the software engineering practice of controlling, organizing, and tracking different versions in history of computer files; primarily source code text files, but generally any type of file. Version control is a component of software configuration management. A ''version control system'' is a software tool that automates version control. Alternatively, version control is embedded as a feature of some systems such as word processors, spreadsheets, collaborative groupware, web docs, and content management systems, e.g., Help:Page history, Wikipedia's page history. Version control includes viewing old versions and enables Reversion (software development), reverting a file to a previous version. Overview As teams develop software, it is common to Software deployment, deploy multiple versions of the same software, and for different developers to work on one or more different versions ...

Microsoft Windows
Windows is a Product lining, product line of Proprietary software, proprietary graphical user interface, graphical operating systems developed and marketed by Microsoft. It is grouped into families and subfamilies that cater to particular sectors of the computing industry – Windows (unqualified) for a consumer or corporate workstation, Windows Server for a Server (computing), server and Windows IoT for an embedded system. Windows is sold as either a consumer retail product or licensed to Original equipment manufacturer, third-party hardware manufacturers who sell products Software bundles, bundled with Windows. The first version of Windows, Windows 1.0, was released on November 20, 1985, as a graphical operating system shell for MS-DOS in response to the growing interest in graphical user interfaces (GUIs). The name "Windows" is a reference to the windowing system in GUIs. The 1990 release of Windows 3.0 catapulted its market success and led to various other product families ...

Rational ClearCase
IBM DevOps Code ClearCase (also known as IBM Rational ClearCase) is a family of computer software tools that supports software configuration management (SCM) of source code and other software development assets. It also supports design-data management of electronic design artifacts, thus enabling hardware and software co-development. ClearCase includes revision control and forms the basis for configuration management at large and medium-sized businesses, accommodating projects with hundreds or thousands of developers. It is developed by IBM. ClearCase supports two configuration management models: UCM (Unified Change Management) and base ClearCase. UCM provides an out-of-the-box model while base ClearCase provides a basic infrastructure (UCM is built on base ClearCase). Both can be customized to support a wide variety of needs. ClearCase can accommodate large binary files, a large number of files, and large repository sizes. It supports branching and labeling. It enables the corre ...

Apache License
The Apache License is a permissive free software license written by the Apache Software Foundation (ASF). It allows users to use the software for any purpose, to distribute it, to modify it, and to distribute modified versions of the software under the terms of the license, without concern for royalties. The ASF and its projects release their software products under the Apache License. The license is also used by many non-ASF projects. History Beginning in 1995, the Apache Group (later the Apache Software Foundation) released successive versions of the Apache HTTP Server. Its initial license was essentially the same as the original 4-clause BSD license, with only the names of the organizations changed, and with an additional clause forbidding derivative works from bearing the Apache name. In July 1999, the Berkeley Software Distribution accepted the argument put to it by the Free Software Foundation and retired their ''advertising clause'' (clause 3) to form the new 3-clau ...

BitKeeper
BitKeeper is a discontinued software tool for distributed revision control of computer source code. Originally developed as proprietary software by BitMover Inc., a privately held company based in Los Gatos, California, it was released as open-source software under the Apache License, Apache-2.0 license on 9 May 2016. BitKeeper is no longer being developed. History BitKeeper was originally developed by BitMover Inc., a privately held company from Los Gatos, California owned by Larry McVoy, who had previously designed TeamWare. BitKeeper and the Linux kernel BitKeeper was first mentioned as a solution to some of the growing pains that Linux was having in September 1998. Early access betas were available in May 1999 and on May 4, 2000, the first public release of BitKeeper was made available. BitMover used to provide access to the system for certain Open-source software, open-source or free-software projects, one of which was the source code of the Linux kernel. The license for ...

GNU General Public License
The GNU General Public Licenses (GNU GPL or simply GPL) are a series of widely used free software licenses, or ''copyleft'' licenses, that guarantee end users the freedom to run, study, share, or modify the software. The GPL was the first copyleft license available for general use. It was originally written by Richard Stallman, the founder of the Free Software Foundation (FSF), for the GNU Project. The license grants the recipients of a computer program the rights of the Free Software Definition. The licenses in the GPL series are all copyleft licenses, which means that any derivative work must be distributed under the same or equivalent license terms. The GPL is more restrictive than the GNU Lesser General Public License, and even more distinct from the more widely used permissive software licenses such as BSD, MIT, and Apache. Historically, the GPL license family has been one of the most popular software licenses in the free and open-source software (FOSS) domai ...

GNU Bazaar (formerly Bazaar-NG, command line tool bzr) is a distributed and client–server revision control system sponsored by Canonical. Bazaar can be used by a single developer working on multiple branches of local content, or by teams collaborating across a network. Bazaar is written in the Python programming language, with packages for major Linux distributions, and Microsoft Windows. Bazaar is free software and in 2008 became part of the GNU Project. It was used by Canonical for their Launchpad code hosting website. The last release was in 2016. In 2025 Canonical announced the retirement of Bazaar. Breezy is a fork of Bazaar.

Distributed Revision Control
In software development, distributed version control (also known as distributed revision control) is a form of version control in which the complete codebase, including its full history, is mirrored on every developer's computer. Compared to centralized version control, this enables automatic management branching and merging, speeds up most operations (except pushing and fetching), improves the ability to work offline, and does not rely on a single location for backups. Git, the world's most popular version control system, is a distributed version control system. In 2010, software development author Joel Spolsky described distributed version control systems as "possibly the biggest advance in software development technology in the astten years". Distributed vs. centralized Distributed version control systems (DVCS) use a peer-to-peer approach to version control, as opposed to the client–server approach of centralized systems.
