Is jest healthy, maintained, and safe?
Yes — jest looks healthy, actively maintained, and free of known advisories today.
The verdict
OSPulse scores jest at 100/100 (minimal risk), computed deterministically from live npm release history, maintainer data, and the OSV vulnerability database. Yes — jest looks healthy, actively maintained, and free of known advisories today.
Its most recent release shipped on 9 May 2026 — 80 days ago — so development is clearly active. Across 381 releases the cadence has been steady, which is a good sign of an ongoing maintenance rhythm. 5 maintainers are listed on npm, so the project isn't hostage to any single contributor.
On the security side, OSV has no advisories on record for jest today. That's reassuring, but "no known advisory" is not the same as "no vulnerability" — it only means nothing has been disclosed and indexed yet.
The signals are green today, but a clean snapshot is not a standing guarantee — packages drift. This is a one-time snapshot of a single package — real projects depend on dozens or hundreds of packages, and any one of them can drift or be compromised between releases. Run your own package.json through the free health check, or have OSPulse monitor your whole dependency tree continuously.
