Is certifi healthy, maintained, and safe?
Maintained, but watch it — certifi has real signals (drift, thin maintenance, or advisories) worth tracking.
The verdict
On the OSPulse health scale, certifi lands at 55/100 — medium risk, computed deterministically from live PyPI release history, and the OSV vulnerability database. Maintained, but watch it — certifi has real signals (drift, thin maintenance, or advisories) worth tracking.
Its most recent release shipped on 22 July 2026 — 6 days ago — so development is clearly active. Across 74 releases the cadence has been steady, which is a good sign of an ongoing maintenance rhythm. PyPI doesn't expose a reliable maintainer count, so bus-factor isn't scored here — treat maintenance depth as unknown rather than assumed.
OSV lists 6 known advisories for certifi, including 1 high. 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.
certifi is usable but carries real signals — 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.
