The Radicale Project is a complete CalDAV (calendar) and CardDAV (contact) server solution.
Calendars and address books are available for both local and remote access, possibly limited through authentication policies. They can be viewed and edited by calendar and contact clients on mobile phones or computers.
Radicale aims to be a light solution, easy to use, easy to install, easy to configure. As a consequence, it requires few software dependencies and is pre-configured to work out-of-the-box.
Radicale runs on most of the UNIX-like platforms (Linux, *BSD, MacOS X) and Windows. It is free and open-source software, written in Python, released under GPL version 3.
