Is left-pad healthy, maintained, and safe?
Probably not — left-pad has gone quiet for over two years and shows the hallmarks of an abandoned package.
The verdict
left-pad earns a health score of 35/100, a high risk rating, computed deterministically from live npm release history, maintainer data, and the OSV vulnerability database. Probably not — left-pad has gone quiet for over two years and shows the hallmarks of an abandoned package.
The last sign of life was 9 April 2018, more than 8 years ago (3073 days); by any practical measure the package looks abandoned. Historically it released far more frequently, so the current silence reads as a genuine collapse in velocity rather than a natural gap. Two maintainers are listed; better than a lone author, but still a thin bench if one steps away.
Security-wise, left-pad currently has a clean OSV record — no published advisories. Keep in mind that reflects what's been disclosed, not a guarantee of safety.
Treat left-pad as a liability to manage: review the evidence above, pin or patch, and evaluate alternatives. 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.
