I’ve seen a lot of recommends for Immich on here, so I have an idea what the answer here is going to be, but I’m looking for some comparisons between it and Photoprism I’m currently using Synology Photos, and I think my biggest issue is it’s lack of metadata management. I’ve gotten around that with MetaImage and NeoFinder. I’m considering moving to something not tied to the Synology environment.
Photoprism better for single user. More stable, prettier, more free license.
Immich has support for multiple libraries, and sharing with your other users. Immich has better ai tools. I'm using immich because I just had a baby and want to see the pictures my wife takes of her.
I also vastly prefer having a single, canon source of photos. I syncthing my library to my laptop for full control (and backup). It's happened before when migrating my server app that I need to reimport all my pictures into a new database. It's super easy if they're all in one spot.
When Photoprism adds multi library, I'll probably switch back. With the main reason being license.
