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.
Yeah, shotwell looks good if you’re a single user and already have all your images stored locally, although if you wanted face tagging DigiKam is also a local only photo management app that does some more advanced stuff.
