whatdeps

A tiny CLI tool that shows basic information about a Python project’s dependencies using few pieces of information from PyPI and GitHub.

it shows

• Supported Python versions - minimum version required
• Disk size - space it takes up
• Last release - when it was last updated on PyPI
• Last push - recent activity on GitHub
• Issues - open/closed ratio (to give a sense of maintenance)
• Stars - popularity on GitHub

Installation

You can install it from PyPI

# With uv
uv tool install whatdeps

# or pipx
pipx install whatdeps

or You can install it in your project environment(not recommended!)

# With pip
pip install whatdeps

# Or uv
uv add whatdeps

Usage

Run it in any Python project with a dependency specification file:

whatdeps

Or point it at a specific file:

whatdeps -f requirements.txt
whatdeps -f pyproject.toml

Example output

Supported formats

• pyproject.toml (PEP 621, Poetry, Hatch)
• requirements.txt and other common formats (requirements-dev.txt, etc.) Dependencies are parsed according to PEP 508. Development dependencies follow PEP 735 groupings.

Packages in requirements.txt are treated as production dependencies; those from other pip requirements files are considered as other dependencies.

Local development

this project uses tox for testing and documentation building, sphinx for docs, and pytest for tests.

build the docs:

tox -e docs

output goes to docs/_build.

run tests on a specific Python version:

tox -e py3.x -- tests

run tests across all environments in parallel:

tox -p -- tests

you can also use uv to create a virtual environment and sync dependencies:

uv sync
