Stoplight vs SuperTokens

SuperTokens scores higher on the AgentReady, 54/100 against 48/100. They differ on 14 of the 41 signals. Which ones decides whether an agent can adopt them without a person watching.

What each one is

Stoplight. Stoplight is a collaborative platform equipping teams with tooling across the API lifecycle to help them build quality APIs efficiently.

SuperTokens. Open source user authentication platform that helps developers build fast, maintain control, and reduce costs.

Where Stoplight is ahead

Stoplight 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 adopt: self-service signup and agent-compatible signup flow. SuperTokens misses those.

And on operate, structured, predictable output and observable execution. SuperTokens misses those.

Where SuperTokens is ahead

SuperTokens passes clear canonical domain, clear product positioning, llms.txt published, llms-full.txt / full agent docs and mcp discoverable, and Stoplight 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. Stoplight misses it.

And on adopt, no mandatory sales call, copyable quickstart and mcp integration available. Stoplight misses those.

What neither does

Both fail openapi / spec quality, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented, 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 is whether an agent can find the product at all without being told it exists. SuperTokens leads 100 to 53. Stoplight misses clear canonical domain, clear product positioning, llms.txt published, llms-full.txt / full agent docs, mcp discoverable; SuperTokens misses nothing.

Understand. Stoplight leads 38 to 31. Stoplight misses openapi / spec quality, authentication documented, 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. SuperTokens leads 60 to 55. Stoplight misses no mandatory sales call, programmatic credential creation, fast time to first request, copyable quickstart, mcp integration available; SuperTokens misses self-service signup, agent-compatible signup flow, programmatic credential creation, fast time to first request.

Operate. Stoplight leads 47 to 24. Stoplight 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.

Pricing

Stoplight starts at $44/mo and has a free tier. SuperTokens starts at $0.02/MAU and has a free tier.
