ViewVC (formerly known as ViewCVS) is a Python/CGI-based system for viewing and interacting with Subversion and CVS repositories through your Web browser. It can browse directories, view changelogs, generate diffs, view arbitrary revisions, and display annotated ("blame") listings. It has full support for tags and branches, and contains a database-backed query system like Bonsai. It was initially based on the cvsweb work by Henner Zeller, but has been ported to Python and dramatically enhanced.
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.
Naraio is a complete package of Apache, MySQL, PHP, Perl, Openssl, Openssh, OpenLDAP, Subversion, Ruby, Python, Phpldapadmin, and Trac. Naraio works with secure LDAP. Users of Trac and Subversion are authenticated with the included OpenLDAP. This is similar to LAMP software with more packages. Naraio is designed to be small and flexible. It is suitable both for small and big enterprises.
File-Picker is a program to display and choose files from your Web site. It supports multiple languages. It uses AJAX to allow the user to interact with the server without reloading the page. You can pick several files at the same time. Its visual interface looks like a file explorer.
JumpBox for Redmine is a virtual machine with a pre-installed instance of Redmine, a project management and issue tracking system for software developers. Redmine provides many of the features in Trac plus support for multiple projects, role based access control, time tracking functionality, Gantt charts, a calendar view, and user self-registration. It includes tight integration with Subversion, and the JumpBox includes everything you need.
