## What it is
A hardened, production-grade Docker image for Radicale, the CalDAV/CardDAV calendar and contacts server. It adds security hardening, configurable authentication, multi-architecture builds, and convenience addons on top of the upstream Radicale server.

## Use cases
- self-host a calendar and contacts sync server
- run a CalDAV/CardDAV server in Docker
- sync calendars and address books across devices
- deploy a secure Radicale instance with docker compose
- replace Google Calendar with a private calendar server

## When to choose
- you want a lightweight, self-hosted CalDAV/CardDAV server with minimal setup
- you need a security-hardened container with non-root execution and configurable auth
- you want multi-architecture support (x86, ARM) for a home server or NAS like Unraid

## When to avoid
- you need a full groupware suite with email, chat, and shared documents
- you prefer a managed calendar service rather than self-hosting
- you need heavy collaboration features like shared team scheduling beyond Radicale's scope

## Facets
- artifact type: service
- maturity: active
- function: http-server, auth, self-hosted, deployment, security
- domain: self-hosted, developer-tools
- platform: self-hosted, cross-platform
- tags: caldav, carddav, radicale, calendar-server, contacts-server, docker-image, podman, docker, linux
