Caution: one person wrote most of the recent commits.
Why
- One person wrote 85% of human commits in the last year, so the project depends on them continuing. (source 1, source 2)
What would change this

Bursts
- Sep 23, 2015 to Sep 25, 2015: about 119 more stars than usual, peak 72 in one day, a spike that tapers off. Outside explanation: a jump in forks.
- Dec 28, 2016 to Dec 28, 2016: about 63 more stars than usual, peak 77 in one day, a spike that tapers off. Outside explanation: a jump in forks.
- Feb 4, 2020 to Feb 4, 2020: about 61 more stars than usual, peak 70 in one day, a spike that tapers off. We couldn't check for an outside explanation.
- Feb 11, 2023 to Feb 22, 2023: about 988 more stars than usual, peak 221 in one day, a shape we can't classify. Outside explanation: a Hacker News post.
Anyone can buy stars for any repo; bursts alone don't prove the owner did.
