Bursts
- Jul 19, 2022 to Aug 22, 2022: about 23.1k more stars than usual, peak 3.3k in one day, a spike that tapers off. Outside explanation: a Hacker News post.
- Sep 10, 2023 to Sep 11, 2023: about 93 more stars than usual, peak 79 in one day, a spike that tapers off. Outside explanation: a jump in forks, a jump in issues and pull requests.
- Mar 4, 2025 to Mar 6, 2025: about 58 more stars than usual, peak 39 in one day, a spike that tapers off. Outside explanation: a jump in forks, a jump in issues and pull requests.
- The star history was reset at some point, so earlier stars aren't counted.
- 1 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.
- The star history has a zero run of 26 weeks or more, so the analysis starts after it.
