Haystack vs OpenAI Agents SDK
An independent, evidence-based trust comparison of Haystack and OpenAI Agents SDK, two Agent Frameworks projects in the HVTracker registry. Scores come from public, checkable signals — supply-chain provenance, OSSF Scorecard, maintenance, and adoption — not popularity.
Haystack leads on trust — 96.7/100 (Grade A) vs 87.7/100 (Grade A), a 9.0-point gap. Note: Haystack's evidence coverage is thinner (coverage B vs A) — its score rests on fewer independent signal types. Full breakdown below.

How to read this: HVTrust (0–100) weighs supply-chain signals (provenance, OSSF Scorecard, signed commits, open license) alongside real-world adoption, scaled by an evidence-confidence factor. Grade bands: A ≥ 80, B ≥ 65, C ≥ 50, D < 50. Signals refresh daily. Full methodology v4.3 →
