pypistats

Python interface to PyPI Stats API to get aggregate download statistics on Python packages on the Python Package Index without having to execute queries directly against Google BigQuery.

Data is available for the last 180 days. (For longer time periods, pypinfo can help, you'll need an API key and get free quota.)

Installation

From PyPI

python3 -m pip install --upgrade pypistats

From source

git clone https://github.com/hugovk/pypistats
cd pypistats
python3 -m pip install .

Example command-line use

Run pypistats with a subcommand (corresponding to PyPI Stats endpoints), then options for that subcommand.

Top-level help:

$ pypistats --help
usage: pypistats [-h] [-V] {recent,overall,python_major,python_minor,system} ...

positional arguments:
  {recent,overall,python_major,python_minor,system}

options:
  -h, --help            show this help message and exit
  -V, --version         show program's version number and exit

Help for a subcommand:

$ pypistats recent --help
usage: pypistats recent [-h] [-p {day,week,month}]
                        [-f {html,json,pretty,md,markdown,rst,tsv}] [-j] [-v]
                        [package]

downloads from mirrors

positional arguments:

You can format in Markdown, ready for pasting in GitHub issues and PRs:

Date range: 2025-12-01 - 2025-12-31

These are equivalent (in May 2019):

pypistats python_major pip --last-month
pypistats python_major pip --month april
pypistats python_major pip --month apr
pypistats python_major pip --month 2019-04

And:

pypistats python_major pip --start-date december --end-date january
pypistats python_major pip --start-date dec      --end-date jan
pypistats python_major pip --start-date 2018-12  --end-date 2019-01

Alternatively, use a local path as the package to look up the name from pyproject.toml or setup.cfg:

$ pypistats recent .

The default is to sort by downloads. To sort chronologically, use --sort date with --daily or --monthly:

NumPy and pandas

To use with either NumPy or pandas, make sure they are first installed, or:

pip install --upgrade "pypistats[numpy]"
pip install --upgrade "pypistats[pandas]"
pip install --upgrade "pypistats[numpy,pandas]"

Return data in a NumPy array for further processing:

import pypistats
numpy_array = pypistats.overall("pyvista", total="daily", format="numpy")
print(type(numpy_array))
# <class 'numpy.ndarray'>
print(numpy_array)
#[['with_mirrors' '2025-04-09' '1.40%' 40033]
# ['without_mirrors' '2025-04-09' '1.39%' 39906]
# ['with_mirrors' '2025-04-07' '1.36%' 39014]
# ...
# ['with_mirrors' '2025-01-18' '0.17%' 4827]
# ['without_mirrors' '2025-01-18' '0.17%' 4795]
# ['Total' None None 2869617]]

Or in a pandas DataFrame:

import pypistats
pandas_dataframe = pypistats.overall("pyvista", total="daily", format="pandas")
print(type(pandas_dataframe))
# <class 'pandas.core.frame.DataFrame'>
print(pandas_dataframe)
#             category        date percent  downloads
# 0       with_mirrors  2025-04-09   1.40%      40033
# 1    without_mirrors  2025-04-09   1.39%      39906
# 2       with_mirrors  2025-04-07   1.36%      39014
# 3    without_mirrors  2025-04-07   1.35%      38837
# 4       with_mirrors  2025-04-06   1.08%      30988
# ..               ...         ...     ...        ...
# 358     with_mirrors  2024-12-28   0.17%       5011
# 359  without_mirrors  2024-12-28   0.17%       4987
# 360     with_mirrors  2025-01-18   0.17%       4827
# 361  without_mirrors  2025-01-18   0.17%       4795
# 362            Total        None    None    2869617
#
# [363 rows x 4 columns]

For example, create charts with pandas:

# Show overall downloads over time, excluding mirrors
import pypistats
data = pypistats.overall("pillow", total="daily", format="pandas")
data = data.groupby("category").get_group("without_mirrors").sort_values("date")

chart = data.plot(x="date", y="downloads", figsize=(10, 2))
chart.figure.show()
chart.figure.savefig("overall.png")  # alternatively

# Show Python 3 downloads over time
import pypistats
data = pypistats.python_major("pillow", total="daily", format="pandas")
data = data.groupby("category").get_group(3).sort_values("date")

chart = data.plot(x="date", y="downloads", figsize=(10, 2))
chart.figure.show()
chart.figure.savefig("python3.png")  # alternatively
