Pusher Channels
Build realtime features your users love. Starting at ~$0/hour.
Easily build realtime features
Build notifications, chat, location tracking, multiplayer gaming, web-page updates, IoT, and many other realtime features. When something happens in your system, it can update web-pages, apps and devices. When an event happens on an app, the app can notify all other apps and your system. For example, If the price of Bitcoin changes, your system could update the display of all open apps and web-pages. Or if Bob starts typing a message, his app could tell Alice’s app to display “Bob is typing …”.
Flexible pub/sub messaging
Pusher Channels has a publish/subscribe model. For example, a mobile app interested in the current Bitcoin price can subscribe to the channel named “bitcoin”. When the price of Bitcoin changes, your system can publish the new price to the channel named “bitcoin”. All subscribers to the “bitcoin” channel will receive the update.
Realtime user lists (presence)
Presence channels show who is online. Apps can use presence channels to show user lists with an “online/offline” status. When Bob’s app subscribes to a presence channel, the app provides the user id “bob”. Alice’s app can subscribe to the same presence channel, then show Alice that Bob is online.
Works everywhere
SDKs for everything: web browsers, iOS and Android apps, PHP frameworks, cloud functions, bash scripts, IoT devices and more. Pusher Channels works everywhere because it uses WebSocket and HTTP, and provides fallbacks for devices that don’t support WebSocket.
Proven security
You can publish sensitive data via private channels. Apps must get permission to subscribe to a private channel. For example, you can restrict channel “private-user-alice” so that only Alice’s apps can subscribe to it. Content is encrypted on the wire with SSL. End-to-end encryption is optional.
Stats and reporting
Pusher Channels tells you everything that’s happening, so you can debug, analyze and record your application’s activity. You can see every connection, publish, and subscribe. Realtime activity is shown in your Channels dashboard and can be sent to your system via webhooks. You can query the current connections and subscriptions via the API and libraries. Metrics are shown in your dashboard and can be exported to your Datadog or Librato account.
