I found this list: https://github.com/meichthys/foss_photo_libraries/tree/main

Which seems to be only a year old. I’ve also installed PhotoPrism and the jury is still out because there’s gaping holes and issues I don’t know if I can resolve.

My focus is not on storage or I’d just do NextCloud. I want all the bells and whistles. Good face detection, scene and object detection / TensorFlow, reverse geocoding with an API like MapBox, automatic album and filenames using machine learning.

I was really hoping there would be one obvious front-runner.
