I’m slowly moving things away from Apple iCloud to my own private infrastructure.

The next thing on my list is photo management.

I currently have several Apple Macs, iPhones, iPads, and a Samsung/Android tablet.

I’m looking for a photo management software I can host myself (of course), but it needs to be integrate well on iOS/iPadOS. It would be handy if I could use the iPhone’s “save photo” functionality (which saves photos to the Apple Photos app) in order to save photos to the self-hosted solution. (Or perhaps a solution that automatically gets new photos from the Apple Photos app and transfers them into the self-hosted software).

It would also be useful if there is a way to run multiple photo libraries on the same device. For instance, I often take photos of family with my iPhone, but also take photos with the iPhone and the Android tablet of work things; it would be handy if I could put these into different libraries, preferably at the time of taking the photo.

Could anyone please recommend something suitable?

Thank you in advance.
