Caution

Caution: one person wrote most of the recent commits.

Why

One person wrote 75% 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.)

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.
