Velyx is a fully managed real-time delivery layer

It lets you build real-time applications without managing WebSocket infrastructure.

Velyx is a fully managed real-time infrastructure that handles all the complexity of WebSocket connections, message routing, fan-out, and horizontal scaling.

What Velyx Handles

  • •WebSocket connection management and lifecycle
  • •Topic-based routing and subscription mapping
  • •Horizontal scaling and load distribution
  • •Message fan-out to thousands of subscribers
  • •Built-in heartbeats and connection health monitoring

Your Responsibility: Just Two Things

1. Backend: Send events to Velyx when something happens
2. Frontend: Update your UI when events arrive

No more managing WebSocket servers or scaling concerns. Velyx just works.

Frontend – Connect and subscribe
const ws = new WebSocket("wss://velyx.me/ws?appId=YOUR_APP_ID");
ws.onopen = () => {
  ws.send(JSON.stringify({
    type: "subscribe",
    topic: "notifications:user-123"
  }));
};
Backend – Publish an event
POST https://velyx.me/publish
x-api-key: YOUR_API_KEY

{
  "topic": "notifications:user-123",
  "payload": { "message": "Your order has shipped!" }
}
