Browser Harness vs Browser Use
An independent, evidence-based trust comparison of Browser Harness and Browser Use, two Browser & Computer Use projects in the HVTracker registry. Scores come from public, checkable signals — supply-chain provenance, OSSF Scorecard, maintenance, and adoption — not popularity.
Browser Harness leads on trust — 88.4/100 (Grade A) vs 73.6/100 (Grade B), a 14.8-point gap. Note: Browser Harness's evidence coverage is thinner (coverage B vs A) — its score rests on fewer independent signal types. Full breakdown below.
