About Inngest
Inngest lets developers write background functions as a series of steps that are each retried and memoized, so a failure part-way through resumes from the last successful step. Functions are triggered by events or schedules and run on your own app's endpoints, whether that's a serverless platform like Vercel or a long-running server, with Inngest handling queuing, concurrency, throttling and rate limits. SDKs cover TypeScript, Python and Go, and a local dev server mirrors production. It's popular with web teams building signup flows, data syncs and multi-step AI agents. The cloud service has a free tier with a monthly allowance of executions and paid tiers priced by executions, concurrency and seats. The engine is open source and can be self-hosted, though many advanced features and observability come with the cloud product.
Best for: Web and serverless teams that want reliable multi-step background functions without managing queues.
