How many people use @esbuild-kit/core-utils?
npm counted 35,619,534 downloads of @esbuild-kit/core-utils 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 35.6M look like real installs. At this scale most of them come from CI, builds and other packages that depend on @esbuild-kit/core-utils, so the number of people behind them is far smaller.
Is @esbuild-kit/core-utils still maintained?
No: the latest version is marked deprecated on npm, with the message “Merged into tsx: https://tsx.hirok.io”. The latest version, 3.3.2, came out on Sep 17, 2023. There were no stable releases in the last 12 months. It was first published on May 10, 2022. npm lists 1 maintainer.
Is @esbuild-kit/core-utils still used?
Downloads with publish spikes removed are up 134% over 3 months and up 1,222% over 11 months. For scale, the median of the 384 packages we track, which lean towards today's most downloaded, is up 164% over 11 months, so this one is ahead of that. Last week, 100% of downloads above the crawler floor were on major version 3, the latest one; the most used single version was 3.3.2, with 100%. Weekdays get 1.27× the downloads of weekends, so there is no clear work-week rhythm. Crawlers account for about 116 downloads a week, roughly 4 per version.
Monthly downloads of @esbuild-kit/core-utils
The busiest month was Oct 2026, with about 3,757,761 downloads a day once publish spikes are removed; the quietest was Dec 2025 (the holiday season), with about 319,340.

Whole months through Oct 31, 2026. Publish spikes are found day by day and summed per month. Real installs apply this week's crawler share to each month's downloads (the upper end also keeps the removed spikes), so they follow npm's curve rather than measure it. The change compares spike-free downloads per day.
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.
