## What it is
pipdeptree is a command line utility that displays the dependency tree of installed Python packages, showing parent-child relationships that pip freeze lacks. It can also report conflicts and cycles, and resolve dependency trees from a package index or a PEP 751 lock file without installing anything.

## Use cases
- show dependency tree of installed python packages
- find which packages depend on a given package
- detect dependency conflicts and cycles in a python environment
- export python dependency graph as  or mermaid or graphviz
- resolve dependency tree from requirements.txt without installing
- inspect dependencies from a PEP 751 lock file offline

## When to choose
- you need to visualize or debug the dependency relationships of packages in a Python environment
- you want machine-readable dependency output (JSON, Mermaid, Graphviz) for tooling or documentation
- you need to check a requirements file or lock file's dependency tree without installing it

## When to avoid
- you need a full dependency resolver or package manager rather than a tree viewer
- you are working with non-Python ecosystems like npm or cargo

## Facets
- artifact type: cli-tool

- domain: developer-tools, version-control
- platform: cli, python, cross-platform
