Caution
Caution: one person wrote most of the recent commits.
Why
- One person wrote 82% of human commits in the last year, so the project depends on them continuing. (source 1, source 2)
What would change this
- A second person takes a substantial share of commits.

Bursts
- Nov 1, 2014 to Nov 21, 2014: about 706 more stars than usual, peak 151 in one day, a spike that tapers off. Outside explanation: a jump in forks, a jump in issues and pull requests.
- Aug 27, 2022 to Aug 28, 2022: about 57 more stars than usual, peak 52 in one day, a spike that tapers off. Outside explanation: a jump in forks, a jump in issues and pull requests.
- Jan 31, 2023 to Feb 2, 2023: about 68 more stars than usual, peak 46 in one day, a spike that tapers off. Outside explanation: a jump in forks, a jump in issues and pull requests.
- Aug 7, 2024 to Aug 8, 2024: about 62 more stars than usual, peak 58 in one day, a spike that tapers off. Outside explanation: a jump in forks, a jump in issues and pull requests.
- Aug 6, 2026 to Aug 9, 2026: about 328 more stars than usual, peak 130 in one day, a spike that tapers off. No outside explanation found, so this burst is unexplained.
- 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.
