Radicale

A simple, free calendar and contact server for CalDAV and CardDAV

About Radicale

Radicale is a free, open-source CalDAV and CardDAV server for calendars, to-do lists and address books. It is deliberately simple: a small Python application that stores data in plain files, needs almost no configuration, and works with the calendar and contacts apps people already use on their phones and computers. Radicale is a good fit for individuals, families and small teams who want to synchronize calendars and contacts through their own server instead of a big cloud platform.
