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.

Head to head, by category

5637 comparisons. Each category has its own page with every pair, grouped by the job the two share.

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.
