Repository health compared

Live analysis · unavailable data stays labelled

Popularity is only one axis. Compare technical scale, maintenance cadence, ownership resilience and change pressure against the same completed analysis that sits behind each report.

Both curves are drawn on shared axes. They are not drawn from a shared source: each series names its own below.

One axis, two sources

The overlay puts both repositories on one axis. It does not always put them on one source: a series not yet read again from GitHub's star history can stop on the date GitHub closed its stargazer list, or be rebuilt from public archive events. Each column below states its own reading.

No row states how much of a history is missing. An archive series records star actions and not unstars, so it can exceed a repository's own star total, and a figure for the difference would be wrong exactly where it looks most precise.

Notes on this comparison

  • Which has more GitHub stars, apache/arrow or pandas-dev/pandas?

    GitHub reports 50,512 stars for pandas-dev/pandas and 17,294 for apache/arrow.

  • Do both star histories cover the same period?

    Not necessarily, and each chart names its own. apache/arrow — GitHub star history · Covers through November 14, 2026 · Still updating. pandas-dev/pandas — GitHub star history · Covers through November 14, 2026 · Still updating. A series read from GitHub's star history runs to its latest read. One read before that existed can stop on the date GitHub closed its stargazer list in July 2026, or come from public archive events, until gitdebt reads it again.

  • How is this comparison computed?

    Star totals come from public repository metadata. The two curves are each repository's stored star series drawn on shared axes, from whichever source is named above. Repository-health figures are computed independently from each project's commit history.
