Nextcloud

tbh nextcloud barebones is great. I don't use it for a full system (as in cloud).

I use it for notes (Joplin is the app on all devices/pc) NC is just its storage/distribution location. Same thing goes with bookmarks (Floccus is the addon, available to all devices/browsers). This is what makes it great.

Next is that I have files / pics on NAS storage, but I can make "external shares" available via NC. So NC is still tiny, but I can see everything I want on my massive NAS.

Using NC properly can be a super useful tool. But there are things to avoid, unless you have huge processor and storage. For example sharing photos. There are much better options than NC offering (Librephotos).

I use LLLM on NC, (because I can) and its pretty good. more than enough for Q&A. It wouldn't beat GPT3.5 but its on par. However you suddenly need 8+GB ram and 4-8 threads to be "responsive" to one user. Fun though!

I do have docserver, fulltextsearch apps and then onlyoffice installed (as a separate VM) so I can actually edit office documents on the fly and its nice, but again I have offloaded it to another VM. so NC stays small and only has the "connector" to the onlyoffice VM.

Its worth it to me for cross platform and pc/compute devices for the bookmarks and notes alone! everything else is just sugar on top!
