Python data tools: star history compared

pandas-dev/pandas

NumPy and pandas are the bedrock nearly every data stack is built on, which makes their long, steady star curves a useful baseline: this is what indispensable looks like. Polars is the disruption story — a Rust-core DataFrame library whose growth since 2022 tracks the whole ecosystem's hunger for speed. Arrow and Dask fill in the picture at the memory-format and distributed ends.

Frequently asked

Which of these python data tools has the most GitHub stars?

pandas-dev/pandas is the most-starred of the python data tools gitdebt compares, with 50,512 GitHub stars as of Nov 2026. It earned its first star in 2010.

Which of these python data tools is growing the fastest?

pandas-dev/pandas added the most stars over the last 90 days of its cached history — about 1,267 new stars. 90-day figures are approximate for older repos, whose history is downsampled.

How is this comparison computed?

The table ranks public repository metadata by current total stars. Each curve is that repository's stored star series — read from GitHub's own star history, or from an older stargazer-list or historical-data read until gitdebt reads it again — drawn on shared axes, with trailing 90-day growth estimated from it. The legend under the chart names each series' own source and coverage date. Repo-health charts come independently from each repository's commit history.
