Deno Deploy vs Restate

Restate scores higher on the AgentReady, 59/100 against 52/100. 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

Deno Deploy. Deno is a fast, open-source, fully Node-compatible JavaScript runtime with TypeScript and everything else you need baked right in.

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

Where Deno Deploy is ahead

Deno Deploy passes structured api reference, and Restate 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: no mandatory sales call and agent-compatible signup flow. Restate misses those.

And on operate, agent compatibility verified. Restate misses it.

Where Restate is ahead

Restate passes clear canonical domain and mcp discoverable, and Deno Deploy 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. Deno Deploy misses it.

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

Finally, on operate, retry behavior documented. Deno Deploy 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, 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. Restate leads 100 to 80. Deno Deploy misses clear canonical domain, mcp discoverable; Restate misses nothing.

Understand. Deno Deploy leads 31 to 23. Deno Deploy misses openapi / spec quality, authentication documented, pricing understandable, 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. Restate leads 70 to 45. Deno Deploy misses self-service signup, programmatic credential creation, free trial or free allowance, fast time to first request, copyable quickstart, mcp integration available; Restate misses no mandatory sales call, agent-compatible signup flow, programmatic credential creation.

Operate. Deno Deploy leads 53 to 41. Deno Deploy misses structured, predictable output, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable; Restate misses structured, predictable output, machine-readable errors, idempotency support, rate-limit behavior predictable, agent compatibility verified.

Pricing

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