The Horde Project

The Horde Project is about creating high quality Open Source applications, based on PHP and the Horde Framework.

The guiding principles of the Horde Project are to create solid standards-based applications using intelligent object oriented design that, wherever possible, are designed to run on a wide range of platforms and backends.
There is great emphasis on making Horde as friendly to non-English speakers as possible. The Horde Framework currently supports many localization features such as unicode and right-to-left text and generous users have contributed many translations for the framework and applications.

Currently Horde Project boasts many applications, some already enterprise-ready and deployed in demanding environments, and some exciting new ones still in development.
