Head-to-head comparisons

Like for like only: two listings are compared when they do the same job, such as web search or LLM inference, never a weather API against a crypto feed. Every pair has the edge per scoring category, the facts, the verdicts and the agent notes side by side. Same data as the tool pages, arranged for a decision.

Side by side

Pick up to four listings above, or tick them in the directory. The comparison runs in your browser from /api/v1/tools.json; the pairs below work without JavaScript.

For companies

Do agents find, use and choose your tools?

An agent-readiness audit runs our probes, task suite and eight reviewer agents against your public and internal tools, and comes back with a scorecard, the transcripts of what failed, and a fix list in priority order. From $2,500, re-run included. We never take payment to move a rank. We do help companies earn one.
