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 put them on one source: since July 2026 a stargazer-list series stops on a fixed date, while a series rebuilt from public archive events keeps receiving points. 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/kafka or redpanda-data/redpanda?

    GitHub reports 33,726 stars for apache/kafka and 12,546 for redpanda-data/redpanda.

  • Do both star histories cover the same period?

    Not necessarily, and each chart names its own. apache/kafka — Historical star data · Covers through September 15, 2026 · Still updating. redpanda-data/redpanda — Historical star data · Covers through September 15, 2026 · Still updating. Since July 2026 GitHub serves a repository's stargazer list only to its own admins and collaborators, so one series can stop on a fixed date while the other keeps flowing from public archive events.

  • 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.
