Clan Core Changelog 26.01.2026

[Luis-Hebendanz]

Clan is a toolkit that makes it easier to manage networks of VPN-connected NixOS machines.
The ultimate goal is to lower the barrier to self-hosted services massively and allow anyone to achieve this without special hardware. As of now, using Clan still requires NixOS knowledge, but it already combines several of our Open-Source projects that you may know (nixos-anywhere, sops-nix, nixos-generators, disko, …) into a uniform CLI.
