Inngest vs Trigger.dev

Inngest scores higher on the AgentReady, 61/100 against 60/100. They differ on 5 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.

Trigger.dev. Trigger.dev is an open source background jobs framework and platform for building AI workflows in TypeScript.

Where Inngest is ahead

Inngest passes structured api reference, and Trigger.dev 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: free trial or free allowance. Trigger.dev misses it.

And on operate, idempotency support. Trigger.dev misses it.

Where Trigger.dev is ahead

Trigger.dev 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 is whether an agent can find the product at all without being told it exists. Trigger.dev leads 100 to 87. Inngest misses search discoverable; Trigger.dev misses nothing.

Understand. Inngest leads 46 to 38. Inngest misses openapi / spec quality, authentication documented, request examples provided, response examples provided, errors and status codes documented; Trigger.dev misses structured api reference, openapi / spec quality, request examples provided, response examples provided, errors and status codes documented.

Adopt. Inngest leads 70 to 65. Inngest misses no mandatory sales call, agent-compatible signup flow, programmatic credential creation; Trigger.dev misses no mandatory sales call, agent-compatible signup flow, programmatic credential creation, free trial or free allowance.

Operate. Inngest leads 41 to 35. Inngest misses structured, predictable output, machine-readable errors, retry behavior documented, rate-limit behavior predictable, agent compatibility verified; Trigger.dev 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. Trigger.dev does not publish one.
