What each one is

Inngest. Inngest is an event-driven durable execution platform that allows developers to run fast, reliable code on any platform without managing queues, infrastructure, or state.

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

Where Inngest is ahead

Inngest passes structured api reference and limits / constraints 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.

It also holds operate: idempotency support. Restate misses it.

Where Restate is ahead

Restate passes search discoverable, and Inngest 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. Inngest misses it.

What neither does

Both fail openapi / spec quality, authentication documented, request examples provided, response examples provided, errors and status codes documented, no mandatory sales call, agent-compatible signup flow, programmatic credential creation, structured, predictable output, machine-readable errors, 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. Restate leads 100 to 87. Inngest misses search discoverable; Restate misses nothing.

Understand is whether an agent can read the docs and work out how the API behaves before calling it. Inngest leads 46 to 23. Inngest misses openapi / spec quality, authentication documented, request examples provided, response examples provided, errors and status codes 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. Both sit at 70/100 here. Inngest misses no mandatory sales call, agent-compatible signup flow, programmatic credential creation; Restate misses no mandatory sales call, agent-compatible signup flow, programmatic credential creation.

Operate. Both sit at 41/100 here. Inngest misses structured, predictable output, machine-readable errors, retry behavior documented, rate-limit behavior predictable, agent compatibility verified; Restate misses structured, predictable output, machine-readable errors, idempotency support, rate-limit behavior predictable, agent compatibility verified.
