I'm interested in hosting something like this, and I'd like to know experiences regarding this topic. The main reason to host this for privacy reasons and also to integrate my own PKM data (markdown files, mainly). Feel free to recommend me videos, articles, other Lemmy communities, etc.

I'd like to sync my markdown notes between devices (laptop and phone), which service is better: Nextcloud or Syncthing? Any other important idea I should know?, like latency times, or maximum number of synced devices, what if I edit the same note from both places without internet and then both get connected to a network... For example, I know Nextcloud let me have a history of the notes.

I have a Raspi 3b+ to play with, and thought about using it as a Google Drive alternative for collaborative docs since there are some cool stuff Google Docs can't do, but LibreOffice do. Any similar experience?
