The verdict

On the OSPulse health scale, express lands at 60/100 — low risk, computed deterministically from live npm release history, maintainer data, and the OSV vulnerability database. Mostly yes — express is maintained, with a couple of watch-items rather than red flags.

Its most recent release shipped on 11 May 2026 — 76 days ago — so development is clearly active. Across 318 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.

OSV lists 5 known advisories for express, of assorted severity. Review whether your version is in the affected range and whether a fixed release is available before depending on it. Each advisory is listed with its OSV/GHSA identifier below.

A couple of watch-items aside, express is a reasonable dependency to rely on; keep an eye on the flagged signals. 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.
