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.
I’ve been using PhotoPrism for the past couple of days and have really liked it.
I was considering Immich, but the rapid development cycle turned me off of it for now. I don’t want to have to deal with keeping up with patch notes and potential breaking changes. Immich also seems more focused on photo backups from your phone, which isn’t quite what I wanted. PhotoPrism just let me upload all my existing photos on the web ui.
I’d say give both a try. Both provide a docker-compose file, so you should be able to bring them up fairly quick.
