(Edit: Not European, but can be self hosted) Ente wants to take on Google Photos with its privacy-first photo storage service | TechCrunch

Immich is not really the same thing. Ente is E2E encrypted and that introduces a significant number of hurdles.

For some reason I also find Photoprism to be so much faster than Immich, for no reason I can explain. I use the function to keep photos outside of these services so it may just be a case of Photoprism caching more aggressively or something.
