About Radicale

Radicale is a small CalDAV and CardDAV server for sharing calendars, to-do lists, and contact lists. It supports events, todos, journal entries, and business cards, and exposes them through CalDAV, CardDAV, and HTTP.

It stores all data on the file system in a simple folder structure and works out of the box with no complicated setup. Access can be limited by authentication, connections can be secured with TLS, and the server works with many CalDAV and CardDAV clients. Radicale can also be extended with plugins.

Radicale is GPLv3-licensed free software. You run it yourself for calendar and contact synchronization, with data kept in plain files rather than a hosted account.
