Chora is built upon the Horde Application Framework and provides a read-only browser interface to any number of version control repositories. Advanced features include a visual branch view of the repository's history, pretty-printed output, annotation, patchsets and basic statistics.
Meld is a visual diff and merge tool. It integrates with most version control systems. The diff viewer lets you edit files in place (diffs update dynamically), and a middle column shows detailed changes and allows merges. The margins show location of changes for easy browsing, and it also features a tabbed interface that allows you to open many diffs at once.
FishEye opens your source code repository to help you understand your code and keep tabs on the people who write it. It lets you view user activity, track code changes, and search and navigate through your repository from any Web browser. Nearly everything in your repository has its own URL, down to every single line of code for every revision. Files, branches, repositories, projects, and even people have their own activity stream. FishEye provides easy navigation, powerful search, historical reporting, configurable file annotation and diff views, changeset analysis, RSS feeds, and integration with JIRA, Crucible, Bamboo, Eclipse, and IntelliJ IDEA. FishEye works with Subversion, CVS, Perforce, Git or Mercurial.
Submin provides a Web-based admin interface to your Subversion and Git repositories. Its features include user/group management, path permission management, the ability to create svn repositories and managing commit email messages. For Subversion, authentication is done with htpasswd/svn authz, so it can use the same login information as apache2/svn (and trac). For Git, ssh is used, and the login information is synched whenever a change is made. The Web interface can also work with NGINX/uWSGI, but the Subversion part only works with Apache.
gitg targets cases where it is useful to provide a graphical representation of Git data or actions. The history view is a good example, where graphical representation helps to get an overview of the repository. gitg does not aim to be an advanced tool that allows access to every feature of Git through a graphical interface. However, it will try to incorporate common actions that might require multiple actions on the command line (like staging, unstaging, reverting, and committing).
0release is a program to generate source and binary releases automatically. With minimal configuration, 0release will generate a source tarball release candidate, build it to create a binary archive, upload them to your Web server, check the uploads, and tag the release in GIT and update the version number. It can run unit-tests and custom actions, such as building documentation, etc. For Zero Install users, it can also upload a signed XML metadata file about the release, allowing these users to upgrade automatically. Releases are signed with your GPG key.
Git# is a C# implementation of the Git version control system for the .NET platform. It is meant to be fully compatible to the original Git implementation in C for Linux. It can be used as a stand-alone command line application (potentially replacing msysGit on Windows) or as a library for applications such as GUI frontends or plugins for IDEs.
