Go Libre: Calendar and Contacts

(part of a series of pages on going libre)

People tend to find moving away from Google Calendar harder than moving from Google’s mail offerings.  It’s not that tricky though.


I’ve done this using Nextcloud, but the underlying systems are CalDav and CardDav.  Other software provide these, for example Radicale (more listed here).

Hosting/web access

You can self-host Nextcloud, but I currently went for simplicity with the hosted offering from GreenNet.  £6 a month isn’t cheap, but I’m thinking this will get me started and I can perhaps migrate away in future.  Anyway, GreenNet are a cool company so I’m OK with this for now.

The web interface to Nextcloud is pretty slick.  The calendar functionality is nice.  The contacts interface is a bit less usable I would say, but it’s OK.

Mobile and Syncing

CalDav/CardDav can be synced to your Android with DavDroid.

You can then view your calendar in something like Etar.

There’s an open issue for viewing CardDav contacts in SimpleContacts.


I’m currently using Evolution for calendaring on my Linux desktop.  I find it a bit clunky but it does the job.  You can subscribe to CalDav and CardDav from it.
