Is PydanticAI safe? PydanticAI scores 86.5/100 (Grade A), ranked #30 of 1204 tracked open-source AI agent projects, on evidence coverage A (4 of 5 independent signal types). The public evidence: its packages ship with cryptographic provenance; OSSF Scorecard rates its supply-chain practices 6.6/10; recent commits are unsigned; last pushed 2026-08-09. Every point is earned from checkable signals — never paid placement. How scoring works →

In Agent Frameworks

How to read this: HVTrust (0–100) weighs supply-chain signals (provenance, OSSF Scorecard, signed commits, open license) alongside real-world adoption. Grade A reflects the trust score band: A ≥ 80, B ≥ 65, C ≥ 50, D < 50. Evidence coverage A is separate — it grades how many independent signal types back the score (4 of 5), so a high score on thin evidence stays visible. Full methodology →

Is PydanticAI safe?

Public supply-chain signals for PydanticAI are strong: it has multiple independent trust indicators in place. This does not replace your own security review, but PydanticAI carries less obvious unverified-evidence risk than projects with thin signals.

Does PydanticAI publish package provenance?

Yes. PydanticAI's package releases carry build provenance attestations, which cryptographically link the published package back to its source repository and CI workflow.

Does PydanticAI have an OpenSSF Scorecard?

PydanticAI has an OpenSSF Scorecard score of 6.6/10. The Scorecard checks for branch protection, signed releases, dependency updates, fuzzing, code review, and other supply-chain hygiene items. See the full check breakdown on this page.

Is PydanticAI actively maintained?

Actively maintained. The repository was pushed to within the last 1 day(s).

What license does PydanticAI use?

PydanticAI ships under MIT. A declared, OSI-approved license is one of the transparency signals HVTrust scores.

Not a safety endorsement. HVTracker describes what public signals show, not whether a project is safe for your use case. Run your own security review before adopting in production.

Maintain PydanticAI?

For maintainers

HVTrust scores PydanticAI from public signals only — we never contact maintainers first. If a signal is wrong, stale, or missing (provenance you publish, a Scorecard you run, signed releases), tell us and we'll review it. Corrections are public and tracked on GitHub.
