How many people actually use yup?
npm counted 16,204,821 downloads of yup in the last 7 days. That count includes every tarball fetch: registry mirrors, security scanners, CI pipelines and crawlers as well as people. humanloads estimates that about 16,204,435 of them (likely range 16,196,384–16,204,821) were real human installs, with high confidence. That puts less than 1% of npm's weekly count down to robots.
How the estimate works
- Cut the spike every new version gets from mirrors in its first days.
- Subtract the flat floor robots download from every version each week.
- Show what is left as a range, with an honest confidence level.
