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.
Throwing another possible contender out there: Nextcloud Memories. Seems like an interesting solution if you’re already running Nextcloud.
There’s an FOSS android gallery app for Nextcloud that’s super nice too
