NixOS is a free and open-source Linux distribution based on the Nix package manager. NixOS uses an immutable design and an atomic update model.[6] Its use of a declarative configuration system allows reproducibility and portability.[7]

NixOS is configured using composable modules, and relies on packages defined in the Nixpkgs project. Package recipes and configurations are written in the purpose-built "Nix language" that ships with the Nix package manager.
