Is httpx healthy, maintained, and safe?
No — httpx carries 1 unpatched critical advisory and should not be adopted without a remediation plan.
The verdict
On the OSPulse health scale, httpx lands at 40/100 — medium risk, computed deterministically from live PyPI release history, and the OSV vulnerability database. No — httpx carries 1 unpatched critical advisory and should not be adopted without a remediation plan.
The newest release dates to 15 September 2025, 315 days back — a gap long enough to suggest the pace is slowing. Historically it released far more frequently, so the current silence reads as a genuine collapse in velocity rather than a natural gap. 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 2 known advisories for httpx, including 1 critical. Open critical advisories are the strongest possible signal to pin to a patched version, replace, or fork before shipping. Each advisory is listed with its OSV/GHSA identifier below.
httpx 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.
