SabreDAV

SabreDAV is a framework and server for CardDAV, CalDAV, and WebDAV. It provides both roles in one program, supporting calendar and contact services as well as general WebDAV functionality. Its scope is not restricted to a single technology: SabreDAV covers the complete set of CardDAV, CalDAV, and WebDAV. It is for users who need server functionality, framework functionality, or both for these technologies. SabreDAV can replace Google Calendar when CalDAV calendar support is the main requirement. However, it is not a direct copy of Google Calendar. SabreDAV is a framework and server rather than the same kind of product, and it also extends beyond calendars by supporting CardDAV and WebDAV alongside CalDAV. Users should therefore expect a different type of software rather than an identical Google Calendar experience.
