Why this estimate
With JavaScript on, this lists what the filter found for this package.
Most used major version: 6, the latest one, with 68% of last week's downloads above the crawler floor. Most used single version: 6.0.0.

How many people use bcrypt?
npm counted 8,026,093 downloads of bcrypt in the last 7 days. Nobody can count people exactly, npm included: it does not record who downloaded what. After removing mirror spikes and crawlers, about 8.02M–8.03M look like real installs. At this scale most of them come from CI, builds and other packages that depend on bcrypt, so the number of people behind them is far smaller.
Is bcrypt still maintained?
Probably not actively: there has been no release in over a year, though that can also mean it is simply finished. The latest version, 6.0.0, came out on May 11, 2025. There were no stable releases in the last 12 months. It was first published on Feb 21, 2011. npm lists 5 maintainers.
Is bcrypt still used?
Downloads with publish spikes removed are up 33% over 3 months and up 148% over 11 months. For scale, the median of the 269 packages we track, which lean towards today's most downloaded, is up 157% over 11 months, so this one is about level with that. Last week, 68% of downloads above the crawler floor were on major version 6, the latest one; the most used single version was 6.0.0, with 68%. Weekdays get 1.5× the downloads of weekends, which fits people at work, though CI follows the same rhythm. Crawlers account for about 242 downloads a week, roughly 4 per version.
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.
