Inngest: Durable Workflows for Agents

Inngest is a durable execution platform. It lets you write long-running functions that survive restarts, retry automatically, and respond to events. For agents, it is a natural fit for multi-step tasks that can take minutes or hours and must not lose state if a process restarts.

• An agent task spans multiple steps with retries and sleeps.
• You need event-driven triggers (new email, webhook, file upload) to start an agent run.
• You want parallelism, debouncing, or rate-limiting without building it yourself.
• Your agent runs in a serverless environment with short execution limits.

• Durable execution. Steps are checkpointed; a crashed function resumes where it left off.
• Built-in retries. Configure retry policies per step or per function.
• Scheduling. Cron and event triggers out of the box.
• Developer experience. Write code as ordinary async functions; Inngest handles the orchestration graph.
• Framework support. Works with Next.js, Node, Python, and Go.

• Newer in the agent space. Examples and patterns for agent workflows are still maturing.
• Managed dependency. Durable execution depends on Inngest's cloud or self-hosted engine.
• Pricing at scale. High-throughput workflows can become a meaningful line item.
• Not a replacement for an agent runtime. It orchestrates steps; the agent reasoning still lives elsewhere.

• Generous free tier for low-volume projects.
• Paid tiers scale with step executions and events.
• Self-hosted option available for teams that need full control.

Teams building agents that must survive restarts, handle retries, and run in response to events. Especially useful for Next.js and Node agents that previously tried to squeeze long tasks into short-lived serverless functions.

• OpenClaw cron and webhooks to trigger Inngest functions.
• LangChain / LlamaIndex agents whose tool calls become durable steps.
• Langfuse for tracing each step of a durable agent workflow.
