Sst vs Vercel

Vercel scores higher on the AgentReady, 93/100 against 44/100. 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

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

Vercel. Vercel is a cloud platform for deploying and scaling web applications, with infrastructure that supports AI agents and applications that scale from zero to millions instantly.

Where Sst is ahead

Sst passes search discoverable and public docs discoverable, and Vercel does not. That is discover, whether an agent can find the product at all without being told it exists.

It also holds adopt: official typescript sdk and official python sdk. Vercel misses those.

And on operate, canonical workflow succeeds and observable execution. Vercel misses those.

Where Vercel is ahead

Vercel 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.

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. Vercel leads 100 to 73. Sst misses clear product positioning, mcp discoverable; Vercel misses search discoverable, public docs discoverable.

Understand. Vercel leads 92 to 31. Sst misses openapi / spec quality, authentication documented, pricing understandable, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented; Vercel misses openapi / spec quality, 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. Vercel leads 100 to 38. 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; Vercel misses no mandatory sales call, programmatic credential creation, fast time to first request, copyable quickstart, official typescript sdk, official python sdk.

Operate. Vercel leads 78 to 35. Sst misses structured, predictable output, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable, agent compatibility verified; Vercel misses canonical workflow succeeds, structured, predictable output, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable, observable execution.

Pricing

Sst does not publish a machine-readable starting price. Vercel starts at $20/mo. and has a free tier.
