- Easy installation of software over URLs.
- Easy transfer of software environments between computers.
- {ref}`Declarative specification of Linux machines <deploying-nixos-using-terraform>`.
- {ref}`Reproducible integration testing using virtual machines <integration-testing-vms>`.
- Avoidance of version conflicts with already installed software.
- Installing software from source code.
- {ref}`Transparent build caching using binary caches <github-actions>`.
- Strong support for software auditability.
- {ref}`First-class cross compilation support <cross-compilation>`.
- Remote builds.
- Remote deployments.
- Atomic upgrades and rollbacks.
