Submin provides a Web-based admin interface to your Subversion repositories. Its features include user/group management, path permission management, and the ability to create svn repositories. It uses htpasswd/svn authz for authentication, so it can use the same login information as apache2/svn (and trac). It works with FF3, IE7, Safari 3, Chrome, and Opera 9.
iF.SVNAdmin is a Web based GUI to your Subversion authorization file. The application doesn't need a database back end or anything similar, since it is completely based on the Subversion authorization- and user authentication file. It includes LDAP support for users and groups. It is also possible to create and delete repositories. A small repository browser for easier access-path creation is also included.
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.
Insurrection is a Web interface and RSS and Atom feed generator for Subversion that uses modern browser features while being as browser agnostic as possible. It has some repository rights administration features and a reasonably good-looking interface that can be customized. RSS and Atom feeds of updates to the project are available.
