Inngest
Durable functions platform replacing queues, state management, and scheduling. Write reliable multi-step code faster without touching infrastructure.
Overview
Inngest transforms how developers build reliable, multi-step applications by providing durable functions that replace traditional message queues, state management systems, and scheduling infrastructure. Rather than cobbling together multiple services (Redis, SQS, cron, etc.), developers write normal code with Inngest's SDK and get automatic retry logic, state persistence, and workflow orchestration. The platform is serverless-first, meaning you deploy your functions to your existing infrastructure (Vercel, AWS Lambda, etc.) while Inngest handles the orchestration layer. This architecture enables developers to write complex, multi-step processes as simple functions without worrying about failure handling, retries, or distributed state.
The Verdict
Who Should Use Inngest?
Best For
- Teams building multi-step workflows without infrastructure complexity
- Serverless applications needing reliable background job processing
- Developers wanting to replace message queues with simple code
- Projects requiring event-driven architectures with retries and scheduling
- Early-stage startups needing fast iteration without infrastructure overhead
Not Ideal For
- Applications requiring complete infrastructure control and customization
- Teams with existing heavy investment in traditional queue systems
- Simple use cases not needing durable execution capabilities
What's Great
- Replaces multiple infrastructure pieces (queues, cron, state) with one SDK
- Write multi-step workflows as normal functions with automatic durability
- Serverless-first with deployment to existing infrastructure
- Built-in retries, error handling, and observability
- Free hobby tier for getting started and experimentation
- Fast development velocity without infrastructure management
Watch Out For
- Vendor lock-in to Inngest's orchestration platform
- Pro tier at $75/month may be costly for hobby projects at scale
- Less flexibility than building custom queue systems
- Learning curve for event-driven architecture patterns
