We provide access to the source of Hippo CMS and Hippo Repository through Subversion (SVN). Released versions can be found under the Tag folder. The latest Trunk source code is not recommended for production use, but does allow you to test out our bleeding-edge code.
Fore more information on SVN access have a look at the Getting the Code page.
You can check out the Hippo Repository 1 source code from our Subversion repository located at http://svn.hippocms.org/repos/hippo/hippo-repository/
See Building Hippo Repository from Source for more instructions.
