I am gradually moving everything to self hosted, and I want to move away from Google Photos. I currently have Nextcloud and sync seems to mostly work, but the default interface seems a bit lacking.
I have tried a few things a while ago (~6 months), but things seem to change quickly.
At the moment, I quite like Nextcloud Memories. It has a similar interface to Google Photos and seems to have relatively quick photo caching, and integrates well with nextcloud. However it doesn’t have a real app and lacks of offline viewing so haven’t fully transistioned yet.
What are you using for your photos and why?
Immich is a very promising app.
Right now it’s probably the most ambitious in terms of functionality, and a lot of people recommend it as an alternative to Google Photos.
However since it’s still in Beta, if you use it, be sure to have a backup of those photos somewhere else. Just in case.
