Radicale is a free, open-source server application that provides CalDAV (calendar), CardDAV (contacts), and WebDAV synchronization, allowing users to share and sync calendars, address books, and to-do lists across devices. It's designed to be lightweight and simple to deploy, with a small dependency footprint, making it popular for self-hosting personal data privately.
