DeerFlow vs Firecrawl
An independent, evidence-based trust comparison of DeerFlow and Firecrawl, two Research & Data projects in the HVTracker registry. Scores come from public, checkable signals — supply-chain provenance, OSSF Scorecard, maintenance, and adoption — not popularity.
Firecrawl leads on trust — 74.7/100 (Grade B) vs 65.8/100 (Grade B), a 8.9-point gap. 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 v4.2 →
