Headroom vs LLM Gateway
Headroom leads on trust: 88.9/100 (Grade A) against 63.8/100 (Grade C), a 25.1-point gap. Headroom leads on supply-chain integrity and adoption, and rests on broader evidence.
Compress tool outputs, logs, files, and RAG chunks before they reach the LLM. 20% fewer tokens for coding agents, 60-95% fewer tokens for JSON, same answers. Library, proxy, MCP server.
Choose Headroom if supply-chain integrity and adoption matter most.

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 v4.4 →
