I would like to store my contacts/addressbook on my own server.

Required features:

  • self-hosted
  • open source
  • can sync to Android and Thunderbird
  • Runs on linux
  • Just for contacts (and nothing else), Nextcloud would be a bit overkill, as there are more leight-weight solutions like Baïkal or Radicale (AFAIR both for contacts and calendars).

  • @Izzy if you have experience with one of these tools, please write an answer. I have used tine20 and nextcloud, and I like nextcloud very much. Works well.

  • I also use Nextcloud, as I need more than just contacts & calendar. The other 2 I have not used myself, otherwise I had written an answer :) I only know 2nd hand that the two should work well and are resource friendly. // Never heard of tine20, though.

  • Not used it myself, but sabre.io/baikal mentioned above has been recommended in past by other people.

Nextcloud can do this. See https://apps.nextcloud.com/apps/contacts

It is ready for self-hosting, open source, can sync to Android and Thunderbird and runs on linux.

Docs how to sync with thunderbird are here: https://docs.nextcloud.com/server/13/user_manual/pim/sync_thunderbird.html

You need the thunderbird plugin CardBook.
