Self hosting used to mean conceding on something. I can honestly say Immich is better in every way than Google Photos or whatever Apple calls it. The only thing is having to set it up yourself.
I have not shared it with many people. But one of my most wanted feature is to completely share by photos with my partner. None of the services I tried (Plex, Synology Photos) had it. In Immich, it’s just a flip of a button.
Ugreen has it. It has conditional albums in which one can setup rules like person, file type, location, anniversary and more and share a live album. Or leave all params empty and simply mirror the entire library.
