## What it is
nix-tree is a terminal application for interactively browsing the dependency graphs of Nix derivations. It lets users explore store paths, inspect closure sizes, and trace why dependencies exist via a TUI.

## Use cases
- find out why a package is in my nix closure
- browse nix store dependency graph interactively
- check closure size of a nix derivation
- visualize nix build dependencies as a dot graph
- trace why-depends between nix store paths
- inspect disk usage of nix packages

## When to choose
- you use Nix and need to understand or debug dependency graphs of store paths
- you want to find what is bloating your system closure
- you need to export a dependency graph in dot format

## When to avoid
- you don't use the Nix package manager
- you need a graphical dependency visualizer rather than a terminal UI

## Facets
