Browse the agent-ready web
Known Good is an index of websites whose agent-facing capabilities have been tested rather than claimed. Every listing records what our probe actually observed — markdown negotiation, an llms.txt, an API catalogue, a working MCP server — and the date it observed it.
Nothing here is bought: listings are earned by probe, graded against a public rubric, and dated so you can see how fresh the evidence is. The index holds 14,356 verified sites across 62 countries, 6,914 of which expose something an agent can act on.
You can add Known Good to your browser's search bar: visit this site once, then pick Known Good from your browser's search-engine settings and search the index straight from the address bar.
