Nix ecosystem
The Nix Ecosystem is a collection of technologies designed to reproducibly build and declaratively configure and manage packages and systems as well as their dependencies. It achieves this by translating the functional paradigm from the program to the system domain by utilizing a dynamic, functional and lazy DSL called the Nix Language for specifying reproducible builds.
Software
| Component | Manual | Description | Use | License |
|---|---|---|---|---|
| Nix | Nix Manual | A package manager that parses Nix expressions specifying reproducible build, putting the result in a store address with a hash of the dependency tree, sidestepping dependency hell and supporting multiversion installs and rollbacks. | Reproducible builds & package management in Linux & Darwin | LGPL-2.1 |
| NixOS | NixOS Manual | A Linux distribution with all components built by Nix, and thus supporting reproducible and declarative system-wide configuration management as well as atomic upgrades and rollbacks. | Declaratively configure desktops, servers & clusters | MIT |
| Nixpkgs | Nixpkgs Manual | The largest community maintained Nix package and NixOS module repository; standard releases of NixOS are hosted here. | Share Nix packages & NixOS modules | MIT |
| Hydra | Hydra Manual | A Nix based continuous build system. | CI build farms | GPL-3.0 |
In addition there are many other applications developed by the Nix community, utilizing and supporting these core technologies.
