Restate vs Temporal

Restate scores higher on the AgentReady, 59/100 against 46/100. 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

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

Temporal. Temporal is an open-source platform for building applications with durable execution, used by companies like OpenAI, Lovable, Replit, Cursor, and Retool to add agentic capabilities to applications.

Where Restate is ahead

Restate passes clear product positioning and mcp discoverable, and Temporal does not. That is discover, whether an agent can find the product at all without being told it exists.

It also holds adopt: official python sdk and mcp integration available. Temporal misses those.

And on operate, retry behavior documented. Temporal misses it.

Where Temporal is ahead

Temporal passes authentication documented, and Restate does not. That is understand, whether an agent can read the docs and work out how the API behaves before calling it.

What neither does

Both fail structured api reference, openapi / spec quality, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented, no mandatory sales call, agent-compatible signup flow, 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 73. Restate misses nothing; Temporal misses clear product positioning, mcp discoverable.

Understand. Temporal leads 31 to 23. Restate misses structured api reference, openapi / spec quality, authentication documented, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented; Temporal misses structured api reference, openapi / spec quality, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented.

Adopt. Restate leads 70 to 45. Restate misses no mandatory sales call, agent-compatible signup flow, programmatic credential creation; Temporal misses no mandatory sales call, agent-compatible signup flow, programmatic credential creation, official python sdk, mcp integration available.

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

Pricing

Restate starts at $0/mo and has a free tier. Temporal starts at $100/mo and has a free tier.

Signal by signal

Which to pick

Restate clears more of the signals an agent needs, so it is the safer default for unattended use. Full profiles: Restate and Temporal. Alternatives to each: Restate, Temporal.
