NixOS for self hosted is awesome! A few lines of code and you have set up a service on bare metal, without needing to think about dependencies. Just look at this beauty, OP:

services.immich = { enable = true; host = "0.0.0.0"; port = 2283; openFirewall = true; };

I really love the idea of Nix. But not a fan of the scripting language.

I do need to test it more.

I do find it hard to update though. I’m not sure if they have released a GUI based interface to make it easier.
