Overview
Baïkal is a PHP CalDAV and CardDAV server built on the sabre/dav framework. It provides a browser-based admin interface for managing users and calendars, making it friendlier to set up than raw sabre/dav. It stores data in SQLite or MySQL and requires only a PHP-capable web server. Deploy manually on shared hosting or via Docker.
Setup and operations guides
Use these practical guides to plan the deployment, security, backups, and recovery work behind this project.
Where it falls short of Calendly
- No web-based calendar or scheduling UI for end users; requires a CalDAV client app
- No public booking page or availability-sharing feature comparable to Calendly
- Development activity has slowed; some sabre/dav edge cases may go unpatched
- HTTPS and reverse-proxy setup is manual and not guided
We list the gaps honestly so you can decide if the trade-off is worth owning your data.
