What it is and what it does
Inngest is a Python SDK that integrates durable, event-driven background job execution into web frameworks without requiring you to set up separate queueing systems. It lets you define functions that respond to events, with built-in support for multi-step workflows where each step can retry independently on failure. Functions can be synchronous or asynchronous, and state is managed automatically by the SDK.
You trigger jobs by sending events to Inngest, either from within your application or externally. During development, a local Dev Server handles execution; in production, Inngest Cloud manages the queue and scheduling. The SDK handles the plumbing of event routing, step retries, and function state, so you write business logic as plain Python functions decorated with Inngest metadata.
Use it for
- Run background tasks triggered by application events without setting up separate infrastructure.
- Build multi-step workflows where each step retries independently and state persists across failures.
- Schedule recurring jobs or delayed execution using event-driven triggers.
- Process async work without blocking HTTP responses in web applications.
- Coordinate complex business logic across multiple services using event-driven architecture.
