What is it?

Davis is a DAV server with an admin dashboard, built on sabre/dav and Symfony 7. It lets you create users, calendars and address books, share calendars with other users, and manage everything from a responsive Bootstrap 5 interface with light and dark modes. It is an alternative to Baïkal, and the database schema can be migrated from an existing Baïkal installation.

On the protocol side, the server supports CalDAV, CardDAV and WebDAV, with calendar sharing, scheduling and server-side subscriptions where the client supports them. Authentication can use HTTP Basic, or IMAP and LDAP through external providers. Extra features include public calendars reachable by link and an automatic birthday calendar that updates when contact birthdates change.

Davis ships with a Dockerfile, a sample docker-compose setup and prebuilt images (one with a bundled Caddy reverse proxy), and it also has a NixOS package and module. It supports MySQL/MariaDB, PostgreSQL and SQLite, and includes a REST API for user and calendar management.
