How many people use unocss?
npm counted 737,151 downloads of unocss 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 735K–737K look like real installs. Noise is under 1% of npm's count. What remains still includes CI and installs as a dependency of other packages.
Is unocss still maintained?
Most likely yes, going by its releases. The latest version, 66.12.0, came out on Oct 26, 2026. The last 12 months saw 32 stable releases, typically 7 days apart, plus 9 pre-releases. It was first published on Oct 4, 2021. npm lists 3 maintainers.
Is unocss still used?
Downloads with publish spikes removed are up 44% over 3 months and up 75% 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 behind that. Last week, 82% of downloads above the crawler floor were on major version 66, the latest one; the most used single version was 66.10.5, with 20%. Weekdays get 1.4× the downloads of weekends, which fits people at work, though CI follows the same rhythm. Crawlers account for about 339 downloads a week, roughly 1 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.
