Nix is a purely functional package manager that builds packages in isolation for reproducible, reliable, declarative package management. It includes its own declarative language and underpins Nixpkgs and NixOS.

Use cases

  • reproducible development environments
  • declarative package management
  • build packages in isolation
  • roll back package upgrades
  • share dev environments across languages
  • create minimal docker images

When to choose

  • you need reproducible builds and environments
  • you want atomic upgrades and rollbacks
  • you manage many language ecosystems with one tool

When to avoid

  • you want simple imperative installs with small disk overhead
  • your team is unwilling to learn the Nix language
  • you need Windows-native support
