Caution
Caution: one person wrote most of the recent commits.
Why
- One person wrote 94% 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.; Only 2 recent issues can be checked for a response, too few to measure response time.)

Responsiveness: of 2 recent issues, n/a got a maintainer reply. Median first response: n/a.
- 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.
- Only 2 recent issues can be checked for a response, too few to measure response time.

Stars

Bursts
- Mar 13, 2021 to Mar 19, 2021: about 273 more stars than usual, peak 72 in one day, a spike that tapers off. Outside explanation: a jump in forks.

- Aug 23, 2022 to Sep 9, 2022: about 1.4k more stars than usual, peak 212 in one day, a shape we can't classify. No outside explanation found, so this burst is unexplained.
- Dec 5, 2022 to Dec 22, 2022: about 1.2k more stars than usual, peak 351 in one day, a shape we can't classify. No outside explanation found, so this burst is unexplained.

- 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.
- 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.
