NixOS merchandise

NixOS is a Linux distribution built around the Nix package manager. Unlike traditional Linux distributions, NixOS is configured using Nix's functional programming language or one of Nix's forks.

NixOS declarative builds and deployments.

Nix is a tool that takes a unique approach to package management and system configuration. Learn how to make reproducible, declarative and reliable systems.

Reproducible

Nix builds packages in isolation from each other. This ensures that they are reproducible and don’t have undeclared dependencies, so if a package works on one machine, it will also work on another.

Declarative

Nix makes it trivial to share development and build environments for your projects, regardless of what programming languages and tools you’re using.

Reliable

Nix ensures that installing or upgrading one package cannot break other packages. It allows you to roll back to previous versions, and ensures that no package is in an inconsistent state during an upgrade.

Since October 2026, FreeWear.org and the NixOS Foundation have entered into a partnership agreement. Enjoy it!!
