I used Photoprism years ago, so my knowledge is probably pretty outdated.
My experience of Photoprism was that mobile was not tightly integrated. At the time I used Syncthing to sync photos — it worked ok for me, but I wasn’t going to set it up on my partner’s phone, for example.
Immich Just Works on both mobile and desktop. Multi user is great, sharing is great, and the local ML and face detection work remarkably well.
Whatever works for you is the best of course! Immich fits the bill for me, and it was very much worth it for me to “buy” it.
Maybe not a service in the typical sense, but setting up your router+server to route your home network traffic through a VPN is a fun project.
My router (MikroTik) supports WireGuard, so I can use it with Mullvad for the whole house—but wg is demanding and it’s a slow router, so while it can NAT at ~1Gbps, it can’t do WireGuard at more than ~90Mbps. So, I set up WireGuard/Mullvad on a little SBC with a fast processor, and have my router use that instead. Using policy based routing and/or mangling, I can have different VLANs/subnets/individual hosts selectively routed through the VPN.
It’s a fun exercise, not sure I implemented it in a smart way, but it works :)
