I'd much rather have Tau'ri calendar software than Goa'uld software of any kind. Who knows what kind of malicious code those snakes have snuck in there?

I'm kinda annoyed that this whole thing was pretty much a pitch for Tauri, and that's a pretty lame looking webapp thing with typescript and whatever browser engine you happen to have lying around

Tauri is tryna be all like "hey look at our install size, it's smaller than electron!!" ... like anyone cares about install size much. The problem is the memory/cpu use of web apps, which tends to 5x a decent native app. Maybe one day, with webassembly...

Any CalDAV server will do. All events are synced across all properly configured devices. No need for emailing individual events. Radicale is an exception. I also find it too simple/barebones.

I have been running Baïkal for years. Multiple users and devices (iOS, Android, MacOS, Linux, Windows etc) with multiple calendars per user, a decent admin web ui, pretty lightweight, easy to install and configure and zero maintenance.

Or just set up your own exchange server.

Personally I miss a calendar frontend that can be used directly in a web browser. Like Google calendar but with everything living on my own server.

Scheduling and event management should be done in a client if you ask me.

What makes Nextcloud unreliable for your use case? I've used the calendar (caldav) functionality for years without issue in sync.
