I know it’s not everyone’s favourite but I use Nextcloud to manage family calendars and contacts and to sync between Mac, PC, iOS and Android.

Definitely Radicale

We have separate calendars (ie we individually sync between our phones and other devices) plus joint calendars that we also sync…

On Android I use davx to sync and Fossify Calendar which allows me to see multiple calendars but only sounds reminders for my personal & joint appointments, not others.

On my laptops I’m currently usong Vivaldi’s built-in calendar and that’s working well for me.

Using baikal here, on docker. Easy to move to another server when I did early this year

No personal knowledge of them but a couple would be sabre/dav and radicale:

• https://github.com/sabre-io/dav

• https://sabre.io/

• https://github.com/Kozea/Radicale

• https://radicale.org/v3.html

edit: and for Android phones the DAVx⁵ is a great caldav and carddav client

I’ve heard numerous recommendations of both sabre and radicale, but ive never used them. I use baikal for both contacts and calendars. It’s simple and it works well.

I like radicale: https://radicale.org/

I recently switched from radicale to baikal. Both are straight forward no frills caldav / carddav managers. Baikal has a more modern UX. My switch came from choosing to use YunoHost to simplify my home server management

I use radicale with great success. Highly recommended. It’s simple and barebone, get the job done, doesn’t get into the way.

Is it fancy and has bells and whistles? No. But who cares given how solid and easy it is.

It has no web calendar, you need an additional tool for that.

Another for radicale. Been using it for years now. Its great.

@nico198x dav server for contacts and calendar so its radicale

Can you elaborate on “sharing”?
