It gets ever-more rickety but it's still usable, and I still use it: the combination of decent face recognition, useful tools, fast UI, locally-stored photos is a combination that I value and I've yet to find an acceptable substitute on Windows or Linux.
If it gets too rickety for you, you should try PhotoStructure. It's locally hosted, can be run on docker/headless or on a desktop, the libraries are read/writeable across platforms, and it has the most robust asset merging and tag inference that I'm aware of.
My beta users are using it for free in exchange for their feedback. I'm hoping to release the final beta within a week. After beta there will be free and paid tiers.
