Northflank vs SuperTokens

SuperTokens scores higher on the AgentReady, 54/100 against 46/100. 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

Northflank. The runtime platform for AI-native companies.

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

Where Northflank is ahead

Northflank passes self-service signup, agent-compatible signup flow and fast time to first request, and SuperTokens 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: structured, predictable output and observable execution. SuperTokens misses those.

Where SuperTokens is ahead

SuperTokens passes llms.txt published, llms-full.txt / full agent docs and mcp discoverable, and Northflank 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. Northflank misses those.

And on adopt, no mandatory sales call, free trial or free allowance, official typescript sdk and mcp integration available. Northflank misses those.

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, programmatic credential creation, 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
