Open Source Python Version Control Software

Diffuse is a graphical tool for comparing and merging text files. It can retrieve files for comparison from Bazaar, CVS, Darcs, Git, Mercurial, Monotone, RCS, Subversion, and SVK repositories.

The CvsGui project is providing several high-end interface clients (WinCvs, MacCvs, gCvs) written in C++ using popular frameworks (MFC, PowerPlant, GTK+) with a scripting support via Python or TCL.

Bundles Portable Python (with PyGTK) and Meld together in an easy to use installer. This allows you to not have to worry about setting up Python or PyGTK and you can keep Meld's Python separate from other Python installations on your machine. ** NOTE ** Meld 3.11 and later now have official installers, hence this project is no longer supported. You can download the new installer here: https://download.gnome.org/binaries/win32/meld/. You should uninstall the old 1.8 version before upgrading.

Dulwich is a Python implementation of the Git file formats and protocols, which does not depend on Git itself. All functionality is available in pure Python. Optional C extensions can be built for improved performance. Dulwich takes its name from the area in London where the friendly Mr. and Mrs. Git once attended a cocktail party. Supported Python versions are Python 3.5 and later. Versions of Dulwich prior to 0.20 also supported Python 2.7. Supported platforms include Linux, Mac OS X and Windows. Dulwich comes with both a lower-level API and higher-level plumbing ("porcelain"). By default, Dulwich' setup.py will attempt to build and install the optional C extensions. The reason for this is that they significantly improve the performance since some low-level operations that are executed often are much slower in CPython.

Git Cola is a sleek and powerful graphical user interface for Git. Git Cola is free software and written in Python (v2 + v3). Git Cola uses QtPy, so you can choose between PyQt6, PyQt5 and PySide2 by setting the QT_API environment variable to pyqt6, pyqt5 or pyside2 as desired. qtpy defaults to pyqt6 and falls back to pyqt6 and pyside2 if pyqt5 is not installed. Git Cola enables additional features when the following Python modules are installed. send2trash enables cross-platform "Send to Trash" functionality. Never run pip install or make install as root or outside of a Python virtualenv! If you don't have PyQt installed then the easiest way to get it is to use a Python virtualenv and install Git Cola into it in "editable" mode. This install method lets you upgrade Git Cola by running git pull.

Meld is a visual diff and merge tool designed to help users compare files, directories, and version-controlled projects with clarity and precision. It supports two-way and three-way comparisons, making it especially useful for reviewing code changes and resolving merge conflicts. Meld provides live comparison updates, allowing users to see differences immediately as files are edited. With built-in navigation tools, users can move quickly between changes and work directly on specific change blocks. The tool integrates with many popular version control systems, helping developers better understand patches and project history. Widely used on Linux and available for Windows, Meld is a reliable solution for managing and understanding differences in code and files.

Works with Plone, Zope, Apache + mod_dav, PyWebDAV, PyDAV, Tamino. 64-bit wxPython used. Upload files or from Web. Update properties. Tested with Plone 5.04

TortoiseHg is a shell extension that let users of Mercurial SCM (Hg) work directly from MS-Windows Explorer. It also includes a command line tool, hgtk, for use on Linux and other platforms.

dbweaver provides a set of tools to extract CREATE statements from a database server and dump them to a text file. These files can be used for editing, source revision control and database migration.

Qct Qt/Python based commit tool

syncmail is a CVS notification tool which can provide a diff for every change to a CVS repository, mailed to specified email addresses. This tool is useful for large communities to monitor activity, and is used for Python and many other active projects.

A hook script usable with TortoiseSVN (and possible other subversion clients/GUIs) providing transparent repository encryption (encryption/decryption at the client side).

SVNChecker is a framework for Subversion pre-commit hook scripts. See the new project page http://svnchecker.tigris.org/.

hg-diff is a simple GUI program to browse mercurial revisions. It is used to display a summary of all changes between two revisions and to display a graphical comparison of the two versions of each changed file.

A-A-P helps you with distributed development of software. Install a program on your system, obtain the sources and make modifications, manage multiple versions of the same project, distribute packages and much more. A-A-P runs on many operating systems.

Albedo is an open-source recommender system aimed at helping developers discover GitHub repositories by learning from activity signals. It treats repositories and developers as a graph of interactions and applies large-scale matrix factorization to model affinities, with Apache Spark providing the distributed data processing. The project focuses on implicit feedback—stars, watches, and other engagement metrics—so it can build useful recommendations without explicit ratings. A reproducible setup and Makefile-driven workflow streamline tasks like spinning up services, loading datasets, training models, and generating candidate lists. Because it’s built around Spark’s scalable primitives, Albedo can experiment on substantial snapshots of GitHub metadata rather than toy corpora. The repo is also educational: it demonstrates a practical end-to-end pipeline from ingestion and feature preparation to training and ranking.

Build System for Java offers an enhanced build environment that ties together deployment instructions, environment configuration and source code as a releaseable entity. A new paradigm for configuration management!

CMGlue (Configuration Management Glue) is a better git-submodule, to manage a workspace which may contains multiple components that may from various version control tools such as Git and SVN (Subversion), or even just from a shared folder.

The CODESH (COllaborative DEvelopment SHell) project provides an automatic persistent logbook for sessions of personal command-line work by recording what and how is being done: for private use/reuse and for sharing selected parts with collaborators.

Very simple project for reporting on cvs repositories. Two independent implementations are being written - one in Java and one in Python. Thus this is also a comparison between the two languages.

CVS-Summary is a program that generates an HTML summary of CVS activity, very similar to that provided by the popular ViewCVS script. CVS-Summary differs from ViewCVS in that it dumps the summary information to static HTML files which can be served by n

ClearVersion is web based tool which allows the effective collaboration of development teams for projects hosted in SubVersion. The Web interface supports the development lifecycle that is required in some processes, such as ISO9000 and TL9000.

CvsShell is a console-based cvs frontend. It provides convenient access to the cvs commands through a shell-like user interface. CvsShell is written in Python.

DVC is built to make ML models shareable and reproducible. It is designed to handle large files, data sets, machine learning models, and metrics as well as code. Version control machine learning models, data sets and intermediate files. DVC connects them with code and uses Amazon S3, Microsoft Azure Blob Storage, Google Drive, Google Cloud Storage, Aliyun OSS, SSH/SFTP, HDFS, HTTP, network-attached storage, or disc to store file contents. Version control machine learning models, data sets, and intermediate files. DVC connects them with code and uses Amazon S3, Microsoft Azure Blob Storage, Google Drive, Google Cloud Storage, Aliyun OSS, SSH/SFTP, HDFS, HTTP, network-attached storage, or disc to store file contents. Harness the full power of Git branches to try different ideas instead of sloppy file suffixes and comments in code. Use automatic metric tracking to navigate instead of paper and pencil. DVC introduces lightweight pipelines as a first-class citizen mechanism in Git.

The DVS Deployable Versioning System is for tracking the development, QA and installation of deployables. It is intended to be used in in-house project environments and uses a CVS style command line interface.
