Frequently Asked Questions

? Is SabreDAV hard to install?

Docker deployment is straightforward, but manual setup requires configuring a PHP server (Apache/Nginx) and optionally a database. Comprehensive documentation helps, but basic server admin experience is recommended for customization.

? Is it a good alternative to Google Workspace for calendar/contact sync?

Yes—if you prioritize self-hosting and open standards over Google’s cloud ecosystem. It excels at syncing calendars/contacts with preferred clients but lacks Google’s email or productivity tools.

? Is SabreDAV completely free?

Absolutely—SabreDAV is licensed under MIT, so it’s free to download, use, modify, and distribute without hidden costs or subscriptions.
