Inngest

Overview

Inngest is a durable workflow engine that has become a popular substrate for production agents. Step functions, event-driven triggers, retries, and observability are first class. The right pick when an agent run has to survive a deploy, retry a tool call, or wait an hour for a webhook.

Best for
Teams whose agents need to be durable, not just clever

Use cases

• Run long agent jobs that survive process restarts and deploys
• Trigger agents on real events without writing a queue layer
• Add retries and timeouts to flaky tool calls
• Compose multi-step agent workflows with explicit checkpoints

Notes

Why it matters

Most agent frameworks assume the run completes in one process. Inngest fixes the durability gap that every production agent eventually hits.

How teams use it in production

Wrap the agent loop as an Inngest function. Wire real-world events as triggers. Stop writing retry logic by hand.

What to watch

Inngest, Trigger.dev, and Temporal are all competing for the durable substrate role. Pick on developer experience and language fit, the durability story is similar across all three.
