Search the Python Package Index (PyPI) across 850,000+ packages and instantly open any project’s complete dependency graph. PyDeps shows direct and transitive subdependencies, the packages that depend on it, version constraints, maintainers, and the open-source license of every node in the tree.
Type a package name to find matching Python libraries, then drill into the interactive graph to understand how they fit together. Compare alternatives, trace where a transitive dependency comes from, and resolve version conflicts before they reach production.
For each result you can review known vulnerabilities from the OSV database, check license compatibility across the whole dependency tree, and download a package together with all of its dependencies as wheels for offline or air-gapped installs. PyDeps is built for developers, security engineers, and DevOps teams who need to see exactly what they are shipping.
