Radicale is an intentionally light-weight and simple CalDAV (calendar) and CardDAV (contact) server that was specifically developed to be easily installed, configured, and managed. It can store multiple calendars and multiple address books. Among the open standards that could be used for the software, CalDAV and CardDAV are one of the best and quite widely used by both clients and servers. Data can be encrypted using SSL and user access can be restricted via multiple authentication policies.
Radicale:

  • allows local and distant access;
  • enables reading, creating, modifying, deleting, storing multiple calendars and contacts;
  • serves up CalDAV and CardDAV content to clients.

Radicale is free and open-source software released under GPL version 3. It is written in pure Python that is object-oriented and OS-independent language. Radicale can work on Python 2.6-3.3 and PyPy > 1.9. It doesn’t have any dependencies, although Radicale can be extended by a number of useful libraries, for instance, for authentication methods.
The installation process is very simple. There is no need in superuser rights or complicated configuration. Usually the only thing that is required from user is launching the main script out-of-the-box and after a couple of minutes software is ready to use.
Radicale doesn’t require a database like Mysql or Postgres since it stores calendars in plain *.ics files and all contacts in an *.vcf format in the filesystem. Both file types are portable. Radicale is a server, not a client and doesn’t provide front-end. Radicale server has no state engine and just manages requests, but it is easy to use and it can run without any configuration.
