How do I find the dependency graph of a Python package?

Search for any package on PyDeps to view its full dependency graph. PyDeps renders an interactive tree and force-directed graph showing every direct and transitive dependency, color-coded by health and security status.

How do I find all subdependencies of a Python package?

PyDeps recursively resolves every transitive dependency (subdependency) of a package, including platform-specific and optional extras. Expand any node in the dependency tree or graph to reveal its complete set of nested subdependencies.

How do I download a Python package with all its dependencies?

Use the bundle download feature in PyDeps to download a package together with all of its resolved dependencies as wheels. This is ideal for offline or air-gapped installs where you cannot reach PyPI directly.

How do I find the reverse dependencies of a Python package?

Open the Dependents tab on any package page in PyDeps to see its reverse dependencies, the other PyPI packages that depend on it. This helps you gauge a package's popularity and the impact of upgrading it.

How do I check a Python package for known vulnerabilities (CVEs)?

PyDeps queries the OSV database in real time and flags known CVEs for a package and its dependencies, showing severity, affected versions, and the version that fixes each vulnerability.

PyDeps - Visual Python Dependency Graph Explorer

Explore Python Package Dependencies Visually PyDeps is a free, interactive explorer for Python (PyPI) packages. Visualize a package's dependency graph, find all subdependencies, see reverse dependencies (dependents), check known CVEs, and download a package with all of its dependencies for offline installs. Search for any Python package to explore its complete dependency tree, analyze transitive dependencies, discover what other packages depend on it, view license information, and identify security vulnerabilities. PyDeps helps Python developers understand package relationships, resolve dependency conflicts, and ensure secure software supply chains for their projects. Features include interactive dependency visualization, offline bundle downloads for air-gapped environments, license compatibility checking, CVE security scanning via OSV database, reverse dependency lookup, and detailed package metadata from PyPI. Built for developers, security engineers, and DevOps teams who need to audit and understand Python package dependencies quickly and efficiently. Explore popular Python packages
