How it is measured
The count comes from GitHub's API: the number of distinct authors whose commits appear in the repository. It accumulates over a project's life, so the slope, how fast new names arrive, matters more than the level.
What the curve shows
Contributor growth is the health metric open-source maintainers actually watch: code can be written by one person, but longevity requires a bench. Flattening slope precedes stagnation by years, and inflections often date governance or sponsorship changes. facebook/react is one of the ecosystem's landmark repositories, which is why its curve doubles as a barometer for its whole corner of the stack.
