agent-swarm vs Concordia
An independent, evidence-based trust comparison of agent-swarm and Concordia, two Multi-Agent Systems projects in the HVTracker registry. Scores come from public, checkable signals — supply-chain provenance, OSSF Scorecard, maintenance, and adoption — not popularity.
agent-swarm leads on trust — 63.9/100 (Grade C) vs 62.4/100 (Grade C), a 1.5-point gap. Note: agent-swarm's evidence coverage is thinner (coverage C vs B) — 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 →
