Photoprism, running on a Raspberry Pi 4. I’m just running it as a single user, and it’s been working well for that. A couple of notes:
Video transcoding is a bit iffy on the rpi, but I’m running it under docker and might just move it all to a mini pc at some point
I don’t have it accessible publicly, but get to it online via Tailscale
No app, but the Web interface is good.
I’m currently running it in “read only” mode (mainly out of initial paranoia when trying it out, but it seems fine) so I have syncthing backing up the photos from my phone wirelessly and occasionally do an import of new images in.
I’ve got a very similar setup now. Only recently adopted tailscale and was previously port tunnelling over SSH to access anything on the local network. SSH is still open, and am just waiting a bit to see if theres any cases where I need it before closing that out too.
Short story: If you don’t need stuff open to the general public, just having Tailscale will probably cover you.
Seconding Syncthing! You don’t need a rpi to get started, but it’s fantastic having it around as the always-on node you can use to sync multipe devices without them being online at the same time.
Thanks for the heads up, I will check that out!
