Radicale – small but powerful CalDAV and CardDAV server

Radicale is a small but powerful CalDAV (calendars, to-do lists) and CardDAV (contacts) server.

Calendar and contact manipulation is available from both local and distant accesses, possibly limited through authentication policies.

It aims to be a lightweight 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.

The installation is very easy, particularly with Linux: one dependency, no superuser rights needed, no configuration required, no database. Installing and launching the main script out-of-the-box, as a normal user, are often the only steps to have a simple remote calendar and contact access.

This is free and open source software.

Features include:

  • Shares calendars and contact lists through CalDAV, CardDAV and HTTP.
  • Supports events, todos, journal entries and business cards.
  • Works out-of-the-box, no complicated setup or configuration required.
  • Can limit access by authentication.
  • Can secure connections with TLS.
  • Works with many CalDAV and CardDAV clients
  • Stores all data on the file system in a simple folder structure.
  • Can be extended with plugins.
