Caution
Caution: one person wrote most of the recent commits.
Why
- One person wrote 76% 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.
- Partly checked: maintenance (Commit counts are estimated: the commit sample stops before the window start, so GitHub's totals were scaled by the sampled bot share.; Authors in the last 90 days are counted from the sampled commits only.)

Stars
CompleteOrganic, confidence high
Bursts
- Nov 26, 2024 to Dec 3, 2024: about 76 more stars than usual, peak 23 in one day, a spike that tapers off. Outside explanation: a jump in forks.
- 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.
