What each one is

Northflank. The runtime platform for AI-native companies.

Sst. SST is a framework that makes it easy to build modern full-stack applications on your own infrastructure.

Where Northflank is ahead

Northflank passes clear product positioning, and Sst does not. That is discover, whether an agent can find the product at all without being told it exists.

It also holds adopt: self-service signup, fast time to first request and copyable quickstart. Sst misses those.

And on operate, structured, predictable output. Sst misses it.

Where Sst is ahead

Sst passes llms.txt published and llms-full.txt / full agent docs, 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: structured api reference. Northflank misses it.

And on adopt, official typescript sdk. Northflank misses it.

What neither does

Both fail mcp discoverable, openapi / spec quality, authentication documented, pricing understandable, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented, no mandatory sales call, programmatic credential creation, free trial or free allowance, mcp integration available, 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
