Koyeb vs Restate

Restate scores higher on the AgentReady, 59/100 against 57/100. They differ on 6 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

Restate. Restate is a lightweight runtime to turn AI agents, workflows, and backend services into durable processes.

Where Koyeb is ahead

Koyeb passes no mandatory sales call and agent-compatible signup flow, and Restate does not. That is adopt, whether an agent can get a key and make its first successful call without a human in the loop.

Where Restate is ahead

Restate 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 operate: retry behavior documented. Koyeb misses it.

What neither does

Both fail structured api reference, 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, 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 is whether an agent can find the product at all without being told it exists. Restate leads 100 to 80. Koyeb misses clear canonical domain, llms.txt published, llms-full.txt / full agent docs; Restate misses nothing.

Understand. Both sit at 23/100 here. Koyeb misses structured api reference, openapi / spec quality, authentication documented, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented; Restate misses structured api reference, openapi / spec quality, authentication documented, 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 70. Koyeb misses programmatic credential creation; Restate misses no mandatory sales call, agent-compatible signup flow, programmatic credential creation.

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

Pricing

Koyeb does not publish a machine-readable starting price and has a free tier. Restate starts at $0/mo and has a free tier.
