Overview#

Socketo Cloud provides a Pusher-compatible WebSocket API for building real-time features like live chat, notifications, and dashboards. If you have used Pusher before, you can migrate by changing only a few configuration values. Unsupported features are listed in the limits documentation.

Core Concepts#

Channels#

Channels are named connections that group subscribers together. When you publish an event to a channel, only clients subscribed to that channel receive it.

• Public channels — anyone can subscribe, no authentication needed
• Private channels — require server-side authentication (private- prefix)
• Presence channels — private channels that also track user identity (presence- prefix)

Events#

Events are messages sent over channels. Each event has a name and a data payload. Your server triggers events via the REST API, and connected clients receive them in real time.

Connections#

Clients connect to Socketo Cloud via WebSocket using the Pusher Protocol (v7). Each connection gets a unique socket_id used for identification and exclusion.

Quick Start#

Install the Pusher client SDK:

npm install pusher-js

Configure and connect:

import Pusher from 'pusher-js'

const pusher = new Pusher('YOUR_APP_KEY', {
  wsHost: 'wss.socketo.dev',
  wssPort: 443,
  forceTLS: true,
  cluster: 'socketo',
  authEndpoint: 'https://your-api.com/pusher/auth',
})

const channel = pusher.subscribe('my-channel')

channel.bind('my-event', (data) => {
  console.log('Received:', data)
})

Socketo Cloud Platform#

Socketo Cloud is a managed serverless WebSocket platform — powered by global edge infrastructure (Cloudflare Workers & Durable Objects), handling auto-scaling, high availability, and real-time analytics so you can focus on building.
