List of revision control software
Local data model 
In the local-only approach, all developers must use the same computer system. These software often manage single files individually and are largely replaced or embedded within newer software.
Open source 
- Revision Control System (RCS) – stores the latest version and backward deltas for fastest access to the trunk tip compared to SCCS and an improved user interface, at the cost of slow branch tip access and missing support for included/excluded deltas.
- Source Code Control System (SCCS) – part of UNIX; based on interleaved deltas, can construct versions as arbitrary sets of revisions. Extracting an arbitrary version takes essentially the same speed and is thus more useful in environments that rely heavily on branching and merging with multiple "current" and identical versions.
Client-server model 
In the client-server model, developers use a shared single repository.
Open source 
- Concurrent Versions System (CVS) – originally built on RCS, licensed under the GPL.
- Subversion (svn) – versioning control system inspired by CVS
- Vesta – build system with a versioning file system and support for distributed repositories
- AccuRev – source configuration management tool with integrated issue tracking based on "Streams" that efficiently manages parallel and global development; replication server is also available
- CA Software Change Manager (originally Harvest/CCC) – change and configuration management tool by Computer Associates
- Autodesk Vault – Version control tool specifically designed for Autodesk applications managing the complex relationships between design files such as AutoCAD and Autodesk Inventor.
- CADES - Designer productivity and version control system by International Computers Limited.
- IBM Rational ClearCase – SCC compliant configuration management system by IBM Rational Software
- codeBeamer – Collaboration and application lifecycle management platform
- IBM Configuration Management Version Control (CMVC) – version control system, no longer available.
- IBM Rational Team Concert – Collaboration and application lifecycle management platform by IBM Rational Software
- IC Manage Global Design Platform (GDP) – design data management for IC design and Perforce infrastructure support.
- MKS Integrity
- Perforce – Free for use in open source projects.
- PVCS – originally Polytron Version Control System, developed by Don Kinzer at Polytron, first released in 1985. Now owned by Serena.
- Quma Version Control System
- SourceAnywhere – version control tool by Dynamsoft.
- StarTeam – coordinates and manages software delivery process by Microfocus, formerly Borland; centralized control of digital assets and activities
- Team Foundation Server - Development software by Microsoft which includes revision control.
- Telelogic Synergy – SCC compliant integrated change management and task-based configuration management system, proprietary of IBM.
- Vault – version control tool by SourceGear (First installation can be used for free)
- Visual SourceSafe – version control tool by Microsoft; oriented toward small teams
- Visual Studio Application Lifecycle Management (previously Team System) – process-based client-server suite of tools by Microsoft for larger development organizations, incorporating work item tracking, reporting, build automation, unit and web testing, and integration with Microsoft Office
Distributed model 
In the distributed approach, each developer works directly with his or her own local repository, and changes are shared between repositories as a separate step.
Open source 
- Aegis – written by Peter Miller, mature software, filesystem-oriented, limited network support. It has support for distributed revision control. It has built-in support for a disciplined process, including peer review and regression testing.
- ArX – written by Walter Landry, started as a fork of GNU arch, but has been completely rewritten
- Bazaar – written in Python, originally by Martin Pool and sponsored by Canonical; decentralised, and aims to be fast and easy to use; can losslessly import Arch archives
- Codeville – written in Python originally by Ross Cohen; uses an innovative merging algorithm
- Darcs – written in Haskell and originally developed by David Roundy; can keep track of inter-patch dependencies and automatically rearrange and "cherry-pick" them using a "theory of patches"
- DCVS – decentralized and CVS-based
- Fossil – written by D. Richard Hipp for SQLite; distributed revision control, wiki, and bug-tracking
- Git – written in a collection of Perl, C, and various shell scripts, designed by Linus Torvalds based on the needs of the Linux kernel project; decentralized, and aims to be fast, flexible, and robust
- GNU arch
- LibreSource – configuration management
- Mercurial – written in Python as an Open Source replacement to BitKeeper; decentralized and aims to be fast, lightweight, portable, and easy to use
- Monotone – developed by the Monotone Team; decentralized in a peer-to-peer way
- SVK – written in Perl by Kao Chia-liang; built on top of Subversion to allow distributed commits
- Veracity - Is another distributed version control system which includes bug tracking and Agile software development tools integrated with the version control features.
- BitKeeper – was used in Linux kernel development (2002 – April 2005)
- Code Co-op – peer-to-peer version control system (can use e-mail for synchronization)
- Sun WorkShop TeamWare – designed by Larry McVoy, creator of BitKeeper
- Plastic SCM – by Codice Software, Inc
- Bill Wohler (10 Oct 1992). "RCS vs SCCS: How do they compare for performance?". Unix — Frequently Asked Questions (7/7). "[RCS ...] is much faster in retrieving the latest version"
- Larry McVoy (11 Dec 2003). "BitKeeper: Why SCCS, rather than RCS?". "RCS is optimized for getting the most recent version on the trunk"
- Bill Wohler (10 Oct 1992). "RCS vs SCCS: How do the interfaces compare?". Unix — Frequently Asked Questions (7/7). "[RCS ...] is more intuitive and consistent"
- "Changes", SVN, Collab Net[dead link]
