Is virtualenv healthy, maintained, and safe?
Maintained, but watch it — virtualenv has real signals (drift, thin maintenance, or advisories) worth tracking.
The verdict
OSPulse scores virtualenv at 55/100 (medium risk), computed deterministically from live PyPI release history, and the OSV vulnerability database. Maintained, but watch it — virtualenv has real signals (drift, thin maintenance, or advisories) worth tracking.
Its most recent release shipped on 21 July 2026 — 7 days ago — so development is clearly active. Across 267 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 virtualenv, 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.
virtualenv 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. Run your own requirements.txt through the free health check, or have OSPulse monitor your whole dependency tree continuously.
