I'm currently using Google Photos for facial recognition, however since they broke their Google Drive integration I'd like to move away from it. For now I am using a combination of Syncthing, the Google Photos interface and rclone.
Is there an API or potential to use this in headless for integration in other apps such as web or Android? What about the automated cards and animations that Google Photos creates? Is there anything like that for Digikam or another app that can be self-hosted?
Nextcloud is self-hosted solution and there is plugin for it that allows you to recognize and cluster faces (to persons) using DLib: https://github.com/matiasdelellis/facerecognition. This might be close to what you need (while Nextcloud is huge software on its own, it is not best photo management app)
