I've been running it for a couple of months. It's under active development, but I personally feel that it's stable and at a good enough place to be a full replacement of Google Photos. In fact, I turned off all uploads to Google in their Photos app, and rely on Immich auto-uploading to my server instead. Of course that means having a robust (preferably off-site) backup and disaster recovery plan.
Amazing!
I think Mylio does this, even in its free version. I don't think it's FOSS though.
Immich is a really good self hosted option
Louis Rossman affiliated group FUTO is pitching in to support development of Immich which hopefully will iron out bugs it currently may have.
This is really the only answer.
this is the way.
Thanks, I will try it.
