Organic, confidence high

Bursts

• Dec 9, 2013 to Dec 11, 2013: about 50 more stars than usual, peak 22 in one day, a spike that tapers off. Outside explanation: a jump in forks.
• Dec 16, 2013 to Dec 22, 2013: about 64 more stars than usual, peak 17 in one day, a shape we can't classify. Outside explanation: a jump in forks, a jump in issues and pull requests.

• Dec 2, 2015 to Dec 3, 2015: about 50 more stars than usual, peak 35 in one day, a spike that tapers off. Outside explanation: a jump in forks, a jump in issues and pull requests.
• Jan 11, 2017 to Jan 13, 2017: about 52 more stars than usual, peak 29 in one day, a flat block of stars. Outside explanation: a jump in forks, a jump in issues and pull requests.

• 407 stars on a repo created before February 2013 have no date, so they aren't in the chart.
• 3 stars GitHub has since removed (tracked since Oct 14, 2026).

Anyone can buy stars for any repo; bursts alone don't prove the owner did.

• The star history looks organic.
• 407 stars on the creation day are undated (before 2013-02-10) and are not counted.
