SmartSVN is a feature-rich and easy-to-use Subversion client. It runs on Linux, Mac OS X, Unix, and Windows. In addition to the normal SVN commands like checkout, update, commit, merge, etc., it provides tag and branch handling (no need to deal with URLs just to switch to a different tag or branch), a built-in file compare and conflict solver, and much more. There is no need to install additional tools for handling SVN working copies, like a command line SVN client or a file comparison tool.
Syncro SVN Client makes document and code sharing between content authors or developers easier. It offers full SVN repository support: checkout, export, import, copy, mkdir, rename, branch, tag, and delete. You can browse repositories, check for changes, commit changes, update your working copy, and examine the revision history. There is no need to install separate applications like a Subversion command line client or a file comparison tool.
repos-tools is a set of command-line utilities to make work on your code repositories faster and easier. It lets you push, pull, build, and do other things on your repositories all at once. The supported (D)VCSes are Git, Subersion, Bazaar, and Mercurial. For GitHub users, forking, following, watching, and dealing with issues can be done from the shell.
SVNBackup allows you to make full and incremental backups of your Subversion repositories without interrupting user activity. It provides functionality not available through "svnadmin hotcopy". It can also be used to migrate between different versions of subversion and different db backends.
SVN2Log automatically generates changelogs from a Subversion repository. You do not need to waste your time and write a special changelog document with a subset of features already described in your SVN commits' descriptions; you decide which parts will be displayed for your users.
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.
svngroup is a collection of tools designed to facilitate advanced access control lists for Subversion repositories. Unlike tools such as svnperms.py or authz, svngroup puts the manipulation of ACLs directly in the hands of group owners. Group owners are those individuals who have been granted "special" privileges in the repository and can make decisions regarding who can and can't submit to a particular location in the repository.
WANdisco's Subversion/CVS Access Control provides full authorization, authentication, access control, and audit capabilities that go well beyond what Subversion and CVS provide on their own. Administrators can implement and maintain the most complex security policies with a minimum of effort. Valuable intellectual property is protected and a complete audit trail is provided, insuring compliance with SOX and other regulatory requirements.
