SourceAnywhere Standalone is also a good one.It looks like a pretty solid product. I like the fact that it seems to be available for many platforms/OS'es. Can you tell us anything on how it compares to, say svn. How well is it's branching support etc?
Both Subversion and SourceAnywhere offer good quality version control features. However, if any of the following situations apply to you, we strongly recommend SourceAnywhere:
1. Easier to use, especially for those who know SourceSafe already.
2. Enhanced security. Password Policy provided and more convenient to manage permissions.
3. Much better integration with Microsoft products. Dynamsoft is a Microsoft Gold Certified Partner. SourceAnywhere passed Optimized for Microsoft Visual Studio, Certified for Windows Vista, and Certified for Windows Server.
4. Better product integration. SourceAnywhere comes with GUI client, command client, SDK, Eclipse plug-in, Visual Studio integration, Dreamweaver/flash integration, cross-platform client. All are in one product.
5. Web development through FTP and multiple sites are supported. SourceAnywhere can automatically detect which files are changed, and only transfer the changed/added files.
6. Distributed development. If you need to access your version control server from a remote location, the SourceAnywhere cache server can greatly improve your developers' productivity.
7. Better support. Dynamsoft is proud of our service.
