Is dayjs healthy, maintained, and safe?
Yes — dayjs looks healthy, actively maintained, and free of known advisories today.
The verdict
dayjs earns a health score of 85/100, a minimal risk rating, computed deterministically from live npm release history, maintainer data, and the OSV vulnerability database. Yes — dayjs looks healthy, actively maintained, and free of known advisories today.
Its most recent release shipped on 26 May 2026 — 64 days ago — so development is clearly active. Across 134 releases the cadence has been steady, which is a good sign of an ongoing maintenance rhythm. Ownership rests on a single maintainer — a bus-factor of one, meaning one person's availability is a single point of failure for everyone downstream.
Security-wise, dayjs currently has a clean OSV record — no published advisories. Keep in mind that reflects what's been disclosed, not a guarantee of safety.
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.
