Free tool

GitHub star history

Paste any public repo to chart how its stars grew over time. Free, no sign-in, aggregate only.

Aggregate only. This free chart never shows individual developers.

What you get

The shape of the momentum, not just the number.

A star count tells you how big an audience is. A star history tells you how it got there: the week a launch landed, the month growth accelerated, the plateau after a release. This chart reconstructs that curve from the date of each star. It is the momentum view, before you meet the people behind it.

Works on any public repo, charting cumulative star growth month by month.
Aggregate only, so no individual developer is ever shown here.
A chart shows how many and when. To see who, sign in and scan the repo.

Common questions

What is GitHub star history?
It is the record of when a repository gained each of its stars over time, plotted as a cumulative growth curve. It shows momentum: a launch spike, steady growth, or a plateau. GitHub shows the total star count but not the growth chart, so a tool reconstructs it from each star’s date.
Is the star history tool free?
Yes. It is free and needs no sign-in. Paste any public repo and it charts the cumulative star growth over time, plus the current total.
Does it show who starred the repo?
No. The chart is aggregate only: a count of stars per month, never a name, email, or individual developer. To see the named people behind the stars, sign in to WarmStars and scan the repo.
How far back does the chart go for a large repo?
For most repos it charts the full history from the first star. For very large repos it charts the earliest stars to keep the tool fast, and always shows the real current total above the chart.
