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.
Synology Photos has been a great alternative, not only to back up my photos/videos to my nas, but as an easy to way to search/organize/share them.
But for the absolute best subject recognition, tagging and search, I purchased Excire Foto (local AI, local database, etc.).
