OpenAI Agents SDK (JS) vs PydanticAI
An independent, evidence-based trust comparison of OpenAI Agents SDK (JS) and PydanticAI, two Agent Frameworks projects in the HVTracker registry. Scores come from public, checkable signals — supply-chain provenance, OSSF Scorecard, maintenance, and adoption — not popularity.
OpenAI Agents SDK (JS) leads on trust — 88.6/100 (Grade A) vs 87.6/100 (Grade A), a 1.0-point gap. Note: OpenAI Agents SDK (JS)'s evidence coverage is thinner (coverage B vs A) — its score rests on fewer independent signal types. Full breakdown below.
