Have you tried Ente.io and have any thoughts on comparison? I only use ente and have been happy with it but hear many good things about immich. Does it support E2EE?
replyImmich is self hosted only so it doesn’t really need e2ee since you can just encrypt the disk of the server. It also runs a load of on server machine learning stuff for automatic people tagging and search.
replyEnte is selfhosted (also has a hosted version) but encourages family use so I think that's why they do E2EE. It also does all the ML on the client side for people tagging and search.
replyMozilla backed it with a grant but that was a few years ago.
