DAViCal

Self-Hosted

Open-source CalDAV & CardDAV server for self-hosted calendars and contacts

Overview

DAViCal is an open-source CalDAV and CardDAV server built to let you self-host calendar and contact data securely. It supports standard protocols, working seamlessly with clients like Apple Calendar, Thunderbird, Android Contacts, and more. Data is stored in PostgreSQL, with features including sharing, access control, and event scheduling. Deployment options include package managers (Debian/Ubuntu) or Docker, though it requires basic server skills to set up PostgreSQL and configure the app. A web-based admin interface helps manage users and resources.
