Source Code

Horde code may be obtained from a variety of sources, depending on your needs. If you intend to contribute to the project, you should clone our Git repository.

You may also browse our Git and older CVS code trees directly online.

Versions

Being a mature project, there are quite a few older versions of our software. Horde 5 is the most recent version of the Application Framework and all new development is to be done against this.

See how the different versions of the various pieces of Horde fit together.
