Nix ecosystem: Difference between revisions

Revision as of 17:22, 15 April 2024

The Core 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.

In addition there are many other applications (Extended Nix Ecosystem) developed by the Nix community, utilizing and supporting these core technologies.

Official ecosystem

Core Components of the Nix Ecosystem
Component	Manual	Description	Use	License
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
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

**The NixOS core ecosystem stack**
NixOS A Linux distribution and configuration system built using Nixpkgs
Nixpkgs A large, community-maintained repository of packages	Hydra A continuous build system built on Nix
Nix A pure and functional build system

Additional inofficial ecosystem

None of the services are required to use Nix. None of these services are affiliated with the NixOS Foundation.

Cachix: binary caches as a service. Free for public caches, subscription for private token-protected caches.
Hercules CI: simplify your CI setup with stateless build agents. Free for open source, per-user subscription for private repositories.
Garnix: nix CI, caching (open beta) and cloud hosting (private alpha) based on Nix as a service. Currently free, but offers commerical plans.
nixbuild.net: remote Nix builders as a service for x86_64 and AArch64. Pay-per-use.
