Link is a 1h42m video interview between Louis Rossmann, FUTO and Immich developers with a introduction to Immich by Louis.
Immich is an open source self-hosted in-development tool to manage image libraries from a central server, and sync/distribute them across your devices, as an alternative to Google Photos. Also see: https://immich.app
The important news here is that FUTO has funded full time development on Immich for 3 years.
Memories and Gallery (actually deprecated by photos) are not the same thing, just to clarify. I’m not in a position to agree or disagree with any of the statements here since I’ve never used immich, but I don’t want people to think that the default photo viewer in nextcloud is what was being discussed here.
