Inngest is a developer platform for building, testing and deploying code that runs in response to events or on a schedule — without spending any time on infrastructure.

How Inngest Works
Select your event trigger
Send events directly from your application with our SDK, configure a webhook, connect an integration.
Write a function
Use our JavaScript & TypeScript SDK to create a background job triggered by an event or on a schedule.
Deploy & Relax
Deploy your functions to your existing platform. Inngest runs your code every time a matching event trigger is received.
No infra to manage.

Serverless functionsJavaScript & TypeScript
Inngest CloudFull history & metrics. 100% managed.
Get things shipped
Inngest's platform enables you to ship features quickly without the overhead.
Out of the critical path
Ensure your API is fast by running your code, asynchronously, in the background.
No queues or workers required
Serverless background jobs mean you don’t need to set up queues or long-running workers.

13 status: result.ok ? 200 : 500,
14 body: `SMS Sent (Message SID: ${result.sid})`

17)The Complete Platform For Everything Async
Our serverless solution provides everything you need to effortlessly
build and manage every type of asynchronous and event-driven job.
No infrastructure to manage
Inngest is serverless, requiring absolutely no infra for you to manage. No queues, event bus, or logging to configure.
A real-time dashboard keeps everyone in the loop
The Inngest Cloud Dashboard brings full transparency to all your asynchronous jobs, so you can stay on top of performance, throughput, and more, without needing to dig through logs.
Automatic Retries
Event Replay
Versioning
Idempotency
Event-driven, as easy as just sending events!
We built all the hard stuff so you don't have to: idempotency, throttling, backoff, retries, replays, job versioning, and so much more. With Inngest, you just write your code and we take care of the rest.
Built for Builders
Supported frameworks
Fits your existing project
Inngest fits right into your current project and workflow so you can focus on shipping.

4 "My function",
5 "demo/some.event",
6 async ({ event }) => {
7 // your business logic
8 return "awesome"

10)No infra
Zero configuration or extra infra to set up
Your code tells Inngest how it should be run so there is no extra yaml or json config to write. You can deploy functions to your existing production setup or to Inngest Cloud
