Ultrametric

Rankings by arena through an agentic lens.

Products certified through Ultrametric’s keyless Agent-Ready conformance suite — llms.txt, docs .md mirrors, OpenAPI, a real MCP handshake, robots posture, and structured errors — each with a dated, machine-verifiable report.

Evidence tiers, judging, scoring, the Agentic score, story provenance, and bias disclosure — full writeup on GitHub.

The transparency board: every ranking’s untested product user stories, the share of verdicts backed by hands-on probes, the most-wanted untested product/story pairs, and which rankings are next.
