Star history

Weekly, from GitHub's stargazers history, over a 30-day window.

Star history

Loading star history…

Growth

Star growth per time window: stars gained, growth percentage, the star count at the start of the period, and whether the figure was measured from our own two-hour intraday snapshots, daily snapshots, or GitHub’s rebuilt star history, for the last 6 hours, the last 12 hours, today, the last 7 days, the last 30 days, and the last year. A period with no current measurement is left blank rather than shown as zero.
Period	Stars gained	Growth	From	Measured
Last 6 hours	—	—	—	Not measured
Last 12 hours	—	—	—	Not measured
Today	+23	0.1%	18.5k on 25 Oct 2026	Daily snapshots
Last 7 days	+36	0.2%	18.5k on 18 Oct 2026	Weekly history
Last 30 days	+102	0.6%	18.4k on 27 Sep 2026	Weekly history
Last year	+821	4.6%	17.7k on 26 Oct 2025	Weekly history

A period with no current measurement is left blank: a delta needs a measurement at both ends of the period. The 6- and 12-hour periods need two intraday measurements exactly that far apart, the day-and-longer periods need snapshots on both dates, and the last year also needs star history from a year ago, which we keep for one year.

Where it stands

Every position is against the 59,266 repositories measured on 24 Oct 2026 — not global GitHub figures.

This repository has not been picked up by the newest daily run yet, so these figures are from 24 Oct 2026 (yesterday). They will refresh on its next run.

Who came first

How we measure this

30 Sep 2026Entered our index

Stars: 18.4k when it entered our index, 18.5k on the last capture we hold (24 Oct 2026), so +49 in that span. That span is our own measurement window, not a claim about what happened before it.

It has never shown up on GitHub Trending while we were watching, so there is no arrival to compare against.
