How many people use arktype?
npm counted 2,842,220 downloads of arktype 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 2.84M look like real installs. At this scale most of them come from CI, builds and other packages that depend on arktype, so the number of people behind them is far smaller.
Is arktype still maintained?
Most likely yes, going by its releases. The latest version, 2.2.9, came out on Oct 20, 2026. The last 12 months saw 13 stable releases, typically 12 days apart. It was first published on Sep 19, 2022. npm lists 1 maintainer.
Is arktype still used?
Downloads with publish spikes removed are up 112% over 3 months and up 628% 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, 100% of downloads above the crawler floor were on major version 2, the latest one; the most used single version was 2.2.9, with 29%. Weekdays get 1.24× the downloads of weekends, so there is no clear work-week rhythm. Crawlers account for about 282 downloads a week, roughly 2 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.
