Stars

Mostly organic, confidence high

Bursts

• May 13, 2021 to May 15, 2021: about 309 more stars than usual, peak 160 in one day, a spike that tapers off. Outside explanation: a Hacker News post, a jump in forks, a jump in issues and pull requests.
• Jul 1, 2022 to Jul 8, 2022: about 310 more stars than usual, peak 91 in one day, a shape we can't classify. Outside explanation: a jump in forks, a jump in issues and pull requests.
• Sep 23, 2023 to Sep 24, 2023: about 109 more stars than usual, peak 90 in one day, a spike that tapers off. Outside explanation: a jump in forks, a jump in issues and pull requests.
• Aug 2, 2026 to Aug 2, 2026: about 63 more stars than usual, peak 71 in one day, a spike that tapers off. Outside explanation: a jump in issues and pull requests.
• Sep 6, 2026 to Sep 13, 2026: about 2.5k more stars than usual, peak 1.3k in one day, a spike that tapers off. No outside explanation found, so this burst is unexplained.
• Oct 3, 2026 to Oct 9, 2026: about 177 more stars than usual, peak 62 in one day, a shape we can't classify. No outside explanation found, so this burst is unexplained.

• 1.5k stars on a repo created before February 2013 have no date, so they aren't in the chart.
• 4 stars GitHub has since removed (tracked since Oct 13, 2026).

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

• Some star bursts have no matching forks, issues, releases, or launch coverage.
• Anyone can buy stars for any repo, so this describes the star history only.
• 1536 stars on the creation day are undated (before 2013-02-10) and are not counted.
