Stytch vs SuperTokens
SuperTokens scores higher on the AgentReady, 54/100 against 51/100. They differ on 9 of the 41 signals. Which ones decides whether an agent can adopt them without a person watching.
What each one is
Stytch. The identity platform for humans & AI agents.
SuperTokens. Open source user authentication platform that helps developers build fast, maintain control, and reduce costs.
Where Stytch is ahead
Stytch passes structured api reference, and SuperTokens does not. That is understand, whether an agent can read the docs and work out how the API behaves before calling it.
It also holds operate: structured, predictable output and observable execution. SuperTokens misses those.
Where SuperTokens is ahead
SuperTokens passes mcp discoverable, and Stytch does not. That is discover, whether an agent can find the product at all without being told it exists.
It also holds understand: pricing understandable. Stytch misses it.
And on adopt, no mandatory sales call, free trial or free allowance, cli available and mcp integration available. Stytch misses those.
What neither does
Both fail openapi / spec quality, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented, self-service signup, agent-compatible signup flow, programmatic credential creation, fast time to first request, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable, 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. SuperTokens leads 100 to 87. Stytch misses mcp discoverable; SuperTokens misses nothing.
Understand. Stytch leads 38 to 31. Stytch misses openapi / spec quality, pricing understandable, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented; SuperTokens misses structured api reference, openapi / spec quality, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented.
Adopt is whether an agent can get a key and make its first successful call without a human in the loop. SuperTokens leads 60 to 29. Stytch misses self-service signup, no mandatory sales call, agent-compatible signup flow, programmatic credential creation, free trial or free allowance, fast time to first request, cli available, mcp integration available; SuperTokens misses self-service signup, agent-compatible signup flow, programmatic credential creation, fast time to first request.
Operate. Stytch leads 50 to 24. Stytch misses machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable, agent compatibility verified; SuperTokens misses structured, predictable output, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable, observable execution, agent compatibility verified.
