Noise: the share of npm's count that mirror spikes and crawlers account for. What remains still includes CI and dependency installs.
Snapshot from the daily build of Nov 6, 2026, last 7 days of npm data. With JavaScript on, this page recomputes it live with a 12-month chart.
By real installs, bcryptjs is ahead of bcrypt by about 2.5×: about 19.8M vs 8.03M a week. npm's raw counts are 8,026,093 for bcrypt and 19,768,769 for bcryptjs, which include mirrors, scanners and crawlers. Mirror spikes and crawlers removed. CI and dependency installs still count, so this is not a head count.
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 a confidence level. It still includes CI and dependency installs, so it is not a count of people.
