I’m a huge fan of Immich (Google Photos clone). I disabled the ML features which kneecaps it a little, but it runs totally fine on an rpi 4 (4GB).

There are other self hosted image solutions, e.g. PhotoPrism, so check out the options first. I used PhotoPrism for a while, but I like the Immich mobile apps (Android and iOS!), so am sticking with it.

I’m also running pihole, Wireguard, and Home Assistant (and fail2ban). Simple nginx web server handles the proxy business for Immich, and I also use that for sharing stuff with friends and family (e.g., a link to a PDF or something). I finally got around to installing SSL certs, and it was almost disappointingly simple! certbot just worked for me.
