How many people use karma?
npm counted 3,820,312 downloads of karma 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 3.82M look like real installs. At this scale most of them come from CI, builds and other packages that depend on karma, so the number of people behind them is far smaller.
Is karma 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, 6.4.4, came out on Jul 29, 2024. There were no stable releases in the last 12 months. It was first published on Mar 9, 2013. npm lists 5 maintainers.
Is karma still used?
Downloads with publish spikes removed are up 8% over 3 months and up 12% 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, 85% of downloads above the crawler floor were on major version 6, the latest one; the most used single version was 6.4.4, with 60%. Weekdays get 1.9× the downloads of weekends, which fits people at work, though CI follows the same rhythm. Crawlers account for about 1,917 downloads a week, roughly 9 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.
