Immich seems cool! Its website warms it's under active development, what do you think of it? What do you think of it compared to other gphotos alternatives?
Until recently, I was using Photoprism. I'd donated via Github a couple of times, as they were promising multi-user capability. They delivered it - behind a paid subscription model. Immich makes it available as is.
I finally took the plunge with Immich a couple of weeks ago, and I love it. I haven't really experienced any major bugs - the facial recognition is... OK. Not (yet) Google Photos good, but getting there. The machine learning has also done a recent job on object recognition. I can usually search for the main object in my ~15k of photos, and get a small enough set of results that I can reasonably quickly find the exact photo I was looking for.
I'm about to onboard my wife onto it, now that I'm satisfied (and have my backup strategy in place). That will be the next test.
The dev is very active and responsive - I posed a question in the tech support channel on the Immich Discord server, on a weekend, and he responded in about an hour with a couple of suggestions. Colour me impressed - he'll be getting my next tech donation, for sure.
Keen to see where he plans on taking it - the app definitely needs some additional features to get closer to parity with Google Photos. Auto-sharing of recognised faces would be great (so my wife and I can auto-share pics of our daughter with each other), plus some basic search filters - dates, places, faces all in a single search would be a good place to start.
