Inngest
Event-driven durable functions for reliable background processing
Overview
Inngest solves the reliability problem that plagues background job processing. Traditional job queues fail silently, lose state on crashes, and require manual retry logic. Inngest's durable functions automatically checkpoint after each step, retry on failure, and resume from where they left off - not from the beginning.
The event-driven model fits naturally with modern application architectures. When something happens in your app (user signs up, payment succeeds, file uploaded), emit an event and Inngest triggers the appropriate functions. Multiple functions can react to the same event, creating loosely coupled workflows.
Inngest runs alongside your existing application - no separate infrastructure to deploy or manage. Add the SDK, define your functions, and Inngest handles queuing, scheduling, retries, and observability. The dashboard shows every function execution, step completion, and failure - making debugging straightforward.

Scheduling
Cron-based and delayed execution without separate infrastructure
Observability
Dashboard showing every execution, step, and failure
Why We Recommend Inngest
Inngest has replaced our ad-hoc background job setups with something dramatically more reliable. The durable execution model means we stop worrying about job failures and focus on building the actual business logic.
