Nix ecosystem
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.
