Kinde vs Ory

Ory scores higher on the AgentReady, 55/100 against 54/100. They differ on 10 of the 41 signals. Which ones decides whether an agent can adopt them without a person watching.

What each one is

Kinde. Modern auth and billing for engineers.

Ory. Ory provides secure, friction-free identity and access management for customers, partners, machines, and agents - with seamless access, granular permissions, and real-time protection.

Where Kinde is ahead

Kinde passes llms-full.txt / full agent docs, and Ory 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 and pricing understandable. Ory misses those.

And on adopt, self-service signup and free trial or free allowance. Ory misses those.

Where Ory is ahead

Ory passes copyable quickstart, official typescript sdk, official python sdk and cli available, and Kinde does not. That is adopt, whether an agent can get a key and make its first successful call without a human in the loop.

It also holds operate: agent compatibility verified. Kinde misses it.

What neither does

Both fail structured api reference, openapi / spec quality, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented, agent-compatible signup flow, programmatic credential creation, fast time to first request, structured, predictable output, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable. 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. Kinde leads 100 to 93. Kinde misses nothing; Ory misses llms-full.txt / full agent docs.

Kinde misses structured api reference, openapi / spec quality, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented; Ory misses structured api reference, openapi / spec quality, authentication documented, pricing understandable, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented.

Adopt. Ory leads 57 to 48. Kinde misses agent-compatible signup flow, programmatic credential creation, fast time to first request, copyable quickstart, official typescript sdk, official python sdk, cli available; Ory misses self-service signup, agent-compatible signup flow, programmatic credential creation, free trial or free allowance, fast time to first request.

Operate is whether an agent can run against it in production and recover when a call fails. Ory leads 53 to 35. Kinde misses structured, predictable output, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable, agent compatibility verified; Ory misses structured, predictable output, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable.
