OK this is not as feature-rich as Piwigo but for those who want something easy to use with facial recognition, support for RAW photos, support for videos, automatic generation of events albums, seeing photos on a map, detection of objects, custom albums, and easy sharing options to friends and family, this may be well all that is needed.
It has an easy Docker install option too, and there is a demo to try out on their page below. If you want more then consider Piwigo which auto-imports from Flickr even.
