Syncthing, python face_recognition [1], a static gallery (sigal [2]), and a few lines of bash and its fully automatic. I can even share links with family.

I am very very happy with immich. See the other commenter's response for many more.

Immich is really good. They have AI semantic search, face grouping, etc. Really similar to Google Photos. Only the mobile app is still not that good.
