Let me get this straight. Ur saying that on the laptop I have two instances, one for me and one for my wife and they both sync to nas instance. I have syncthing installed via apt on my Debian laptop. How do u get two instances going?

I just find nextcloud bloated for my use case.

I think hoarder must ne similari to wallabag which i use solely for preserving content I like. I use floccus plus WebDAV for bookmarks saving because floccus is avaible for android too. So bookmarks are the same on all my devices. Sounds like linkwarden does both but I can’t find android app which is a killer for me. Waljabag also is available for android where idomost of my reading.
