Introducing the Inngest CLI: build, test, and ship serverless functions locally

Event mesh

Everything you need to build production ready event driven apps.

Event driven serverless function example
  • Developer CLI
  • Auto-gen'd types & schemas
  • Retries & replays built in

How it works

Our Event Mesh makes it easy to build event-driven apps.

One event hub

We ingest all your events via our one-click integrations, SDKs, or webhooks.

Serverless Functions

Your code is executed instantly against the events you specify. Automatic retries built-in.

Unified History

View logging, payload data, and audit-trails for your events and functions together in one place.

Send your events from anywhere

Use our SDKs or webhooks to send events from your app

curl -X POST "" \
  -d '{"name": "test.event", "data": { "email": "" } }'

Build with superpowers

Create, deploy, and monitor event-driven serverless functions with confidence.

Create and test with real data

Start building functions with our auto-typed example payloads or use historical event data. Easily run fuzz testing and handle type changes without issues.

Event payload

Deploy with confidence

Get realtime insights into which payloads are causing errors. Instantly rollback to any previous version. And replay failed payloads when an issue is resolved.

Deployed functions and events

Monitor your serverless functions

Get granular visibility into event → function pathways including conditional execution, function chains, and how often each function runs.
