What are you using as a Google photos alternative? Currently I’m using Nextcloud but I’m thinking of switching to a more dedicated solution.
I mainly need to upload photos from my device automatically, have an UI to see and classify them, albuns and sharing.
External libraries do this, but fwiw when I tested Immich I ended up with a ton of missing thumbnails in my external library and there seemed to be no way to detect and repair them. That was a deal breaker for me and I went back to Photoprism. Immich looks really great though other than that.
