We believe you can massively improve the user experience and engagement of your existing applications by making them realtime. Pusher lets you do that quickly and simply with our hosted API. In the Pusher challenge, we want to see the innovative ways you can turbo-charge your apps with a sprinkling of Pusher magic.

Pusher uses Websockets to handle the notifications. You can sign up for a developer account to get the development ball rolling but the deadline is midnight (GMT) on October 16th (just five days away!) so dive in and get realtime quickly for your chance to win!

Do you want to spice up your web applications by making them real-time - but don't want to create new infrastructures for the sole purpose of getting web sockets to work? In this article, we'll explore how to use and implement Pusher, an HTML5 WebSocket-powered real-time messaging service for your applications.

Pusher uses HTML5 WebSockets to handle the messaging, so you'll need a browser that supports it to follow along with the tutorial. The Pusher API provides and endpoint for authorization and the push and pull of messages. In the tutorial, they create a simple chat application that gives a "Who's Online" and a window with the latest messages.
