Horde

The Horde Project is a group of developers who write web applications using the Horde Application Framework, itself a product of the project. The Horde Application Framework is a flexible, modular, general-purpose web application framework written in PHP. It provides an extensive array of components that are targeted at the common problems and tasks involved in developing modern web applications: libraries for dealing with preferences, compression, browser detection, connection tracking, MIME, and more. The Horde Framework, by itself, does not provide any significant end user functionality; it provides a base for other applications and tools for developers. You will probably want to install some of the available Horde applications, such as IMP (a webmail client), or Kronolith (a calendar). There is a list of Horde applications and projects at This software is OSI Certified Open Source Software. OSI Certified is a certification mark of the Open Source Initiative . Instructions for installing Horde can be found in the file INSTALL in the doc/ directory of the Horde distribution. Horde LLC runs a number of mailing lists, for individual applications and for issues relating to the project as a whole. Information, archives, and subscription information can be found at Lastly, Horde developers, contributors and users also make occasional appearances on IRC, on the channel horde on the Freenode Network (irc.freenode.net).
