Python Package Index (PyPI)

PyPI is the official index every pip install (and uv add, and poetry add) pulls from — over 600,000 projects, searchable by name or keyword, each with its own page showing versions, dependencies, and release history. It’s infrastructure more than a resource you browse directly, but worth knowing how to search well when evaluating an unfamiliar package’s maintenance status and release cadence before depending on it.

See our Top 100 Python Packages page for what’s actually getting downloaded most from it right now.
