Inngest vs Temporal

Inngest scores higher on the AgentReady, 61/100 against 46/100. They differ on 9 of the 41 signals. Which ones decides whether an agent can adopt them without a person watching.

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.

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 Inngest is ahead

Inngest 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 understand: structured api reference and limits / constraints documented. Temporal misses those.

And on adopt, official python sdk and mcp integration available. Temporal misses those.

Finally, on operate, idempotency support. Temporal misses it.

Where Temporal is ahead

Temporal 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 understand: authentication documented. Inngest misses it.

What neither does

Both fail openapi / spec quality, 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, retry behavior documented, 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. Inngest leads 87 to 73. Inngest misses search discoverable; Temporal misses clear product positioning, mcp discoverable.

Understand. Inngest leads 46 to 31. Inngest misses openapi / spec quality, authentication documented, request examples provided, response examples provided, errors and status codes documented; Temporal misses structured api reference, openapi / spec quality, 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. Inngest leads 70 to 45. Inngest 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. Inngest leads 41 to 35. Inngest misses structured, predictable output, machine-readable errors, retry behavior documented, 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

Inngest starts at $99/mo and has a free tier. Temporal starts at $100/mo and has a free tier.

Signal by signal

Which to pick

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