I guess there is no one-size-fits-all for self hosting. We all have different requirements. Mine is NAS based, so hence Unraid. I think mostly we all rotate around the core of photo storage, and Immich is likely what’s fuelling a lot of self hosting now as it’s a legit alternative to Google Photos. As I’ve moved out of the Google eco system now for everything; it creeps me out to think how much of my information they used to have access to.
