Our verdict on DAViCal

DAViCal is a self-hosted server for sharing calendars through the CalDAV protocol. It stores calendaring resources in iCalendar format and supports multiple users or clients reading and writing shared entries. Teams can create multiple calendars per user, delegate read and write access, apply calendar access control lists, and manage free/busy availability. It runs as a web application backed by PostgreSQL and PHP, with web and Linux support. The product is aimed at organizations and self-hosters that want to operate their own calendar infrastructure rather than adopt a hosted calendar workspace.

Its strongest fit is as a calendar storage and access layer. LDAP authentication and directory synchronization support directory-managed environments, while ICS importing and remote calendar binding help connect existing calendar resources. The CalDAV model also supports external clients, giving organizations flexibility in how users access calendars. DAViCal is distributed as free software under the GNU General Public License, so its value is concentrated in open-source infrastructure and control rather than packaged end-user conveniences.

The trade-off is a narrow, server-focused product scope. DAViCal does not provide a DAViCal mobile app, booking pages, scheduling links, or video-meeting integration. Users should choose it when shared CalDAV storage, delegation, access control, and self-hosting are the priorities. Organizations seeking a ready-made scheduling experience, built-in booking workflows, or a broader end-user platform should look for an alternative with those capabilities.
