NixOS 23.11 released Announcement

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

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

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

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.

Choose from Thousands of Packages

The Nix Packages collection (Nixpkgs) is a set of over 80 000 packages for the Nix package manager.
