Porter vs Sst

Porter scores higher on the AgentReady, 55/100 against 44/100. 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

Porter. Porter is a platform as a service (PaaS) that runs in your own cloud.

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

Where Porter is ahead

Porter passes mcp discoverable, and Sst 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. Sst misses it.

And on adopt, self-service signup, free trial or free allowance, fast time to first request, copyable quickstart and mcp integration available. Sst misses those.

Finally, on operate, retry behavior documented. Sst misses it.

Where Sst is ahead

Sst passes structured api reference, and Porter 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: agent-compatible signup flow. Porter misses it.

What neither does

Both fail clear product positioning, openapi / spec quality, authentication documented, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented, no mandatory sales call, programmatic credential creation, structured, predictable output, machine-readable errors, 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. Porter leads 87 to 73. Porter misses clear product positioning; Sst misses clear product positioning, mcp discoverable.

Understand. Sst leads 31 to 23. Porter misses structured api reference, openapi / spec quality, authentication documented, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented; Sst misses openapi / spec quality, authentication documented, pricing understandable, 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. Porter leads 70 to 38. Porter misses no mandatory sales call, agent-compatible signup flow, programmatic credential creation; Sst misses self-service signup, no mandatory sales call, programmatic credential creation, free trial or free allowance, fast time to first request, copyable quickstart, mcp integration available.

Operate. Porter leads 41 to 35. Porter misses structured, predictable output, machine-readable errors, idempotency support, rate-limit behavior predictable, agent compatibility verified; Sst misses structured, predictable output, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable, agent compatibility verified.

Pricing

Porter starts at $6/mo with no free tier. Sst does not publish one.
