The verdict

On the OSPulse health scale, enzyme lands at 40/100, a medium risk rating, computed deterministically from live npm release history, maintainer data, and the OSV vulnerability database. Probably not. enzyme has gone quiet for over two years and shows the hallmarks of an abandoned package.

The last sign of life was 20 December 2019, more than 6 years ago (2462 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. 3 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 enzyme 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.

enzyme is usable but carries real signals, so pin versions, watch for new advisories, and keep a fallback in mind. 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.
