nix-du
Visualize which Nix garbage collection roots to delete to free space in your Nix store.
What is nix-du?
nix-du is a command-line tool for the Nix package manager that visualizes disk usage in the Nix store. It generates dependency graphs showing which garbage collection roots are retaining packages, helping users identify what to delete to free up space. It solves the problem of understanding why certain packages persist and how much space they consume.
Nix and NixOS users, system administrators, and developers who manage Nix-based environments and need to optimize storage by removing unnecessary packages.
Developers choose nix-du because it provides clear, visual insights into Nix store dependencies that traditional garbage collection tools lack, enabling targeted space reclamation without guesswork. Its focus on diagnostics without store modification ensures safe analysis.
