Immich is leagues ahead of Photo Prism, but Photo Prism is definitely an alternative.
Setting up a server isn't difficult if you can follow a YouTube video. Are you looking to host it yourself at home? or through a hosted service?
Either way, you could find a YouTube video that is easy to follow along for setting this up with Docker if you're at all curious. If not, hopefully someone can answer your original question!
lmao. You said you can't help with ente.io so you clearly haven't testes all services, but yeah sure, recommend something. Very objective. (Nothing against immich itself, I used it myself and liked it.)
