Push real-time data to any devices, anywhere.

Fastly Fanout is the push platform built on open technology that gives your API real-time superpowers.

Push Architecture Done Right

No need to build your own "stream server thing". We've done the hard work for you.

Hybrid reverse proxy and message broker.

Augment your existing API with push capability.

Designed for interoperability.

Any HTTP-based backend, including serverless/FaaS, can manage long-lived streams.

Self-hosted or cloud. It’s up to you.

Use our massive network with a custom domain name or run the software on your own servers.

How It Works

Integrate with the Fanout proxy and notify it when there’s data to send.

Step 1: Add an endpoint on your backend that responds with Fanout instructions.

Step 2: Configure Fanout's proxy to route requests to your backend server.

Step 3: Call the Fanout API when there's data to send out.

Devices will now be able to connect to the endpoint through the Fanout proxy and listen for data.

Focus on your business, not reinventing the wheel.

Real-time data that’s responsive, reliable, and scalable to millions of devices.

Keep all of your API logic in one place.

No need to write a separate backend in a different language just to push data.

Pick your protocol.

Choose from a variety of push mechanisms: HTTP streaming, WebSockets, and more.

Compatible with API management.

Apply the benefits of your API management system (e.g. authentication) to your real-time endpoints. Simply chain the proxies.
