I was talking about this docker image: https://hub.docker.com/r/collabora/code/
correction from my side: it is the development edition, which means rolling release and possibly less stability, but it is worth a try imho (but i do not use it personally)
you could have a look at etherpad. seems pretty cool and is extensible with plugins. i don’t know about resource consumption and security aspects, tho, because i don’t personally use it. there are also a few publicly usable instances to test it out (see their github). keep in mind, however, that those come with plugins and do not reflect the vanilla state of the tool.
- Nextcloud, mainly for calendars and contacts; occasionally for sharing files with others.
- Syncthing for syncing files.
Quick question: have you thought about hosting Radicale and filebrowser instead of NextCloud? I think that would be definetly lighter on your system.
Also: I have read lots of mixed opinions whether mailservers should be selfhosted - what is your take on this? Do you know about problems reaching the big player mailservers?
that and screen sharing
