Inngest is a developer-focused platform for building reliable background jobs, event-driven workflows, and AI applications. It provides durable execution, retries, scheduling, and workflow management without requiring developers to manage separate queue or worker infrastructure.

Inngest works with standard application code, making it useful for building long-running workflows and background processes that need to continue reliably even when individual steps fail.

How Inngest Works

  • Send an Event: Your application sends an event such as a user signup or completed order.
  • Trigger a Function: Inngest identifies the function connected to that event and starts the workflow.
  • Run Steps: The workflow executes individual steps using standard application code.
  • Pause and Resume: Steps can pause for a specific period and resume later without losing their state.
  • Retry Failures: Failed steps can automatically retry without restarting the entire workflow.
  • Monitor Execution: Developers can track workflow execution, errors, performance, and usage.
