Overview

What is Radicale?

Radicale is a lightweight, open-source CalDAV, CardDAV, and HTTP server dedicated to sharing calendars and contact lists. It manages events, tasks (todos), journal entries, and business cards (vCards), and runs out-of-the-box without complex configuration.

Its philosophy is simplicity: a single dependency, no superuser privileges required, no database. All data is stored in the filesystem within a simple folder structure, with optional Git integration for versioning. It supports multiple authentication methods (htpasswd, LDAP, OAuth2, PAM, IMAP, Dovecot) and flexible rights management and collection sharing.

The server runs on Linux, BSD, macOS, and Windows, relies on Python, and is well-suited for containerized deployment. Its extension-based architecture allows adding custom authentication or storage backends. Radicale is distributed under the GPLv3 license.

Host Radicale at DINAO

No managed container for Radicale: this application is installed on a VPS hosted in France (0,25 vCPU / 128 Mo / 1 Go minimum).

Radicale needs a level of access to the machine that the managed container, shared between several customers, does not give. Two VPS hosted in France: DINAO installs and manages it for you, or you administer it yourself.

Technical reason: bind mount of a host path (named volumes only in the managed offer).

Frequently asked questions

You might be wondering…

About Radicale 6 questions

Do my calendars and contacts remain private?

Yes. Your appointments, tasks, and address books are stored on your dedicated instance in France. No data is shared or used for other purposes.

Which applications can I connect?

Radicale relies on open CalDAV and CardDAV standards: Thunderbird, Apple Calendar and Contacts, DAVx⁵ on Android, Evolution, and most market clients synchronize directly.

Where is the data hosted?

On DINAO infrastructure in France, in one of the available datacenters. Your calendars and contacts never leave the country.

Are technical skills required?

No for usage: you simply add the account to your calendar app. You install and maintain the application on your VPS; DINAO does not manage it unless you add the paid management option.

Can I change my plan or export my data?

Yes. You can upgrade or downgrade at any time. Since data is stored in standard files (iCalendar/vCard), it remains exportable — no proprietary lock-in.

Is this application tested before it is offered?

This application has not yet passed our automatic deployment test. It can still be installed, but we invite you to contact us before ordering: we will then test it as a priority. The deployment template used was last updated on 3 July 2026. Each new version released by the publisher triggers this test again: the date above therefore follows the version actually offered.

In which data centre is my service hosted?

In France, in DINAO's private racks within two third-party data centres: Free Pro in Marseille (MAR02) and Euclyde DC1 in Sophia-Antipolis. The operator provides the building, power, cooling and physical security; DINAO operates everything inside its racks, entirely and independently.
