Inngest
Event-driven workflow platform for running durable, retriable background functions in serverless environments. Supports step functions with automatic retries, fan-out, and sleep-until patterns — well suited for multi-step AI pipelines. SDKs for TypeScript/JavaScript and Python; integrates with Next.js, Vercel, and AWS Lambda.
Solid choice for most workflows
You need to run multi-step background jobs (email sequences, data syncs, webhooks) reliably without managing queues, workers, or retry logic yourself.
Functions execute reliably with automatic retries and state management across steps. You get visual workflow debugging, instant rollbacks, and event history for replay. Expect minimal operational overhead—Inngest handles scaling and concurrency. Quirk: functions must be stateless and idempotent; long-running steps (>15 min) work but require careful timeout design.
You're building AI pipelines or complex workflows that need to pause, wait for external events, fan out to multiple parallel tasks, or coordinate across services.
Workflows are readable as code and debuggable step-by-step. Fan-out and batching work smoothly. Pause-and-resume patterns (e.g., 'wait up to 1h for customer response') are native. Performance is good for typical SaaS workloads; extreme scale (millions of concurrent paused workflows) may require tuning.
You need to integrate webhooks from external services (Stripe, GitHub, Slack) and trigger internal workflows in response, without building custom webhook handlers.
Webhook handling is straightforward and reliable. Inngest stores full event history, so you can replay or debug webhook-triggered workflows. Latency is low (milliseconds to seconds depending on function complexity).
Function execution model requires statelessness and idempotency
Inngest calls your functions and manages retries at the step level. If a step fails partway through, Inngest re-invokes it. Your code must be idempotent (safe to run multiple times) and stateless. Side effects (database writes, API calls) must be carefully ordered to avoid duplicates or inconsistencies.
Long-running functions and timeout edge cases
While Inngest supports long-lived workflows via steps and sleep patterns, individual step execution has implicit timeout constraints. If a step takes too long (exact limit depends on your deployment), it may be interrupted. Design steps to complete within reasonable time windows (minutes, not hours) or use `sleep()` + `waitForEvent()` to break up work.

What It Actually Does
Inngest lets you build reliable background jobs that automatically retry if they fail, making it easy to string together multi-step tasks in serverless apps without managing infrastructure yourself.
