How many people use preact?
npm counted 56,339,702 downloads of preact 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 56.3M look like real installs. At this scale most of them come from CI, builds and other packages that depend on preact, so the number of people behind them is far smaller.
Is preact still maintained?
Most likely yes, going by its releases. The latest version, 11.2.0, came out on Nov 6, 2026. The last 12 months saw 21 stable releases, typically 19 days apart, plus 5 pre-releases. It was first published on Sep 11, 2015. npm lists 6 maintainers.
Is preact still used?
Downloads with publish spikes removed are up 85% over 3 months and up 388% 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 ahead of that. Last week, 98% of downloads above the crawler floor were on major version 10, not the latest one; the most used single version was 10.29.8, with 33%. Weekdays get 1.4× the downloads of weekends, which fits people at work, though CI follows the same rhythm. Crawlers account for about 2,037 downloads a week, roughly 7 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.
