Railway vs Sst

Railway scores higher on the AgentReady, 87/100 against 44/100. They differ on 15 of the 41 signals. Which ones decides whether an agent can adopt them without a person watching.

What each one is

Railway. Railway is an all-in-one intelligent cloud provider that makes it easy to provision infrastructure, develop locally, and deploy to the cloud.

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

Where Railway is ahead

Railway passes clear product positioning and 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: authentication documented and pricing understandable. Sst misses those.

And on adopt, self-service signup, free trial or free allowance and mcp integration available. Sst misses those.

Finally, on operate, agent compatibility verified. Sst misses it.

Where Sst is ahead

Sst passes search discoverable and public docs discoverable, and Railway 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. Railway misses it.

And on adopt, official typescript sdk and official python sdk. Railway misses those.

Finally, on operate, canonical workflow succeeds and observable execution. Railway misses those.

What neither does

Both fail openapi / spec quality, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented, no mandatory sales call, programmatic credential creation, fast time to first request, copyable quickstart, structured, predictable output, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable. 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. Railway leads 83 to 73. Railway misses search discoverable, public docs discoverable; Sst misses clear product positioning, mcp discoverable.

Understand is whether an agent can read the docs and work out how the API behaves before calling it. Railway leads 100 to 31. Railway misses structured api reference, openapi / spec quality, 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. Railway leads 88 to 38. Railway misses no mandatory sales call, programmatic credential creation, fast time to first request, copyable quickstart, official typescript sdk, official python sdk; 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. Railway leads 78 to 35. Railway misses canonical workflow succeeds, structured, predictable output, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable, observable execution; Sst misses structured, predictable output, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable, agent compatibility verified.

Pricing

Railway does not publish a machine-readable starting price and has a free tier. Sst does not publish one.
