Apify. Apify is the largest marketplace of trusted tools for AI.

Diffbot. Diffbot builds AI models that read and transform the unstructured web into knowledge.

It also holds adopt: cli available. Diffbot misses it.

Where Diffbot is ahead

Diffbot passes search discoverable and public docs discoverable, and Apify does not. That is discover, whether an agent can find the product at all without being told it exists.

It also holds understand: authentication documented, pricing understandable and limits / constraints documented. Apify misses those.

And on adopt, self-service signup, free trial or free allowance, official typescript sdk and official python sdk. Apify misses those.

Finally, on operate, canonical workflow succeeds and structured, predictable output. Apify misses those.

What neither does

Both fail openapi / spec quality, request examples provided, response examples provided, errors and status codes documented, no mandatory sales call, programmatic credential creation, fast time to first request, copyable quickstart, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable, observable execution, agent compatibility verified. If your agent needs any of those, you will be building it yourself either way.

Score, pillar by pillar

The AgentReady splits into four pillars, scored separately, because a product can be easy to find and still impossible to adopt.

Discover. Apify leads 100 to 93. Apify misses search discoverable, public docs discoverable; Diffbot misses clear canonical domain.

Understand. Apify leads 67 to 54. Apify misses openapi / spec quality, authentication documented, pricing understandable, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented; Diffbot misses openapi / spec quality, request examples provided, response examples provided, errors and status codes documented.

Adopt. Apify leads 63 to 55. Apify misses self-service signup, no mandatory sales call, programmatic credential creation, free trial or free allowance, fast time to first request, copyable quickstart, official typescript sdk, official python sdk; Diffbot misses no mandatory sales call, agent-compatible signup flow, programmatic credential creation, fast time to first request, copyable quickstart, cli available.

Operate is whether an agent can run against it in production and recover when a call fails. Apify leads 67 to 35. Apify misses canonical workflow succeeds, structured, predictable output, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable, observable execution, agent compatibility verified; Diffbot misses machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable, observable execution, agent compatibility verified.
