DAV Server

WebTop DAV Server is a CalDAV / CardDAV server based on SabreDAV.

DAV Clients notes


  • Lightning has no autodiscovery support: each calendar must be added manually using the URL obtained via WebTop menu “Calendar Links”.
  • Thunderbird has no native support for CardDAV: the Cardbook add-on works fine, with easy setup and autodiscovery.


  • Use opensource Outlook CalDav Synchronizer, supporting both CardDAV and CalDAV


  • Install and use the OpenSync app from Google PlayStore, providing both CardDAV and CalDAV in one easy configuration.


  • Configure native iOS CalDAV and CardDAV accounts, simple and with autodiscovery.
