Flakes are a feature in Nix for managing project dependencies and outputs in a self-contained and purely reproducible way. They use two main files: flake.nix: Declares the project’s inputs (dependencies, like a specific version of nixpkgs) and its outputs (packages, NixOS configurations, dev shells). flake.lock: An auto-generated file that pins the exact Git commit of every input, ensuring that builds are identical for everyone, everywhere. In short, flakes solve the problem of dependency management by locking versions explicitly, making projects truly portable and reproducible. They are the modern replacement for the older Nix channels system. ...

Home Manager is a Nix-powered tool for reproducible management of the contents of users’ home directories. This includes programs, configuration files, environment variables and, well… arbitrary files. The following example snippet of Nix code: Backlinks nixos

nixos NixOS is a Linux distribution that uses a unique, declarative approach to system configuration. Instead of modifying configuration files directly, you define your entire system—packages, services, users, etc.—in a single file (configuration.nix). NixOS then builds the system from that declaration. This provides three main benefits: Reproducibility: The same configuration file always produces the exact same system. Atomic Upgrades: System changes complete fully or not at all, preventing broken states. Rollbacks: You can instantly revert to any previous system configuration if something goes wrong. This reproducibility also includes per-user settings via home-manager. ...
