Koyeb vs Sst

Koyeb scores higher on the AgentReady, 57/100 against 44/100. They differ on 13 of the 41 signals. Which ones decides whether an agent can adopt them without a person watching.

What each one is

Koyeb. Developer-friendly serverless platform designed to let businesses and developers easily deploy reliable and scalable applications globally, with high-performance infrastructure for AI inference, sandboxes, and microservices on CPUs, GPUs, and accelerators

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

Where Koyeb is ahead

Koyeb 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: pricing understandable. Sst misses it.

And on adopt, self-service signup, no mandatory sales call, free trial or free allowance, fast time to first request, copyable quickstart and mcp integration available. Sst misses those.

Where Sst is ahead

Sst passes clear canonical domain, llms.txt published and llms-full.txt / full agent docs, and Koyeb 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. Koyeb misses it.

What neither does

Both fail openapi / spec quality, authentication documented, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented, programmatic credential creation, structured, predictable output, 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

The AgentReady splits into four pillars, scored separately, because a product can be easy to find and still impossible to adopt.

Discover. Koyeb leads 80 to 73. Koyeb misses clear canonical domain, llms.txt published, llms-full.txt / full agent docs; Sst misses clear product positioning, mcp discoverable.

Understand. Sst leads 31 to 23. Koyeb 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. Koyeb leads 90 to 38. Koyeb misses 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. Both sit at 35/100 here. Koyeb misses structured, predictable output, machine-readable errors, retry behavior documented, 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

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