The verdict

OSPulse scores pydantic at 68/100 (low risk), computed deterministically from live PyPI release history, and the OSV vulnerability database. Mostly yes — pydantic is maintained, with a couple of watch-items rather than red flags.

Its most recent release shipped on 22 May 2026 — 67 days ago — so development is clearly active. Across 201 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 4 known advisories for pydantic, 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, pydantic 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 requirements.txt through the free health check, or have OSPulse monitor your whole dependency tree continuously.
