Sabre/dav - CalDAV and CardDAV server, alternative to Radicale.

[timconsidine]

An extremely old thread, but here goes.

My Radicale instance broke, tried to fix it, but realised that I never liked it much anyway. So looked at alternatives and found Baikal.

Now packaged and released as a Community App.

NextCloud did (mostly) work on our iPhones. Mostly refers to unreliable sync between users, groups and devices. Sync via NextCloud worked most of the time but was quite confusing without good defaults. At a personal level, it was okay but I'd hate to count on it working across dozens or hundreds of users. I wouldn't trust a NextCloud hooked-up device not to share personal contacts with the server either.

In 2025, we gave up on Apple mobile devices (iPhones) due to ever increasing invasiveness of iCloud and lack of security (iCloud data shared with all the three letter agencies) over time. We moved to LineageOS and GrapheneOS and in worst case de-Googled Android (the latter I do not recommend as it's a time-sink: to cut off Google functionality will degrade, the LineageOS guys work thousands of hours to de-Google Android, better to enjoy their hard work).

Hard to believe that in 2026 only Apple, Microsoft and Google have reasonably functional contact sharing!

If somebody at Cloudron has some better ideas on how to share contacts in a SMB please let the world know.

did you look at the contacts app here ?
or explore Baikal CardDav ?
I have not yet - I don't generally use contacts app.

For very similar reasons out of frustration to not being able to fix basic contacts syncing issues and improve those apps, we have been building a contacts app for Cloudron from scratch with some decent UI but more importantly a carddav server which we can fix for all use-cases we can test. It is still pretty fresh project, but works well at least with thunderbird, davx/davdroid, gnome.

@foliovision if you like, give it a go and if you hit syncing issues just open a thread at https://forum.cloudron.io/category/221/contacts any other feedback or bugreports are of course very welcome to get this going.

The project lives at https://git.cloudron.io/apps/contacts

Yes, I've tried all of them, including sponsoring etesync/tasn for two and a half years and paying for Fruux for many years. I finally got fed up when Tom refused to add support for Apple Silicon Macs (etesync requires that Rosetta 2, about 2GB of RAM, run at all times).

etesync only syncs two users though so it's of limited use in a group or even family setting.

@nebulon

Your contacts project sounds very exciting. We'll definitely try it.
