1 to 1 and Group Chat
Build instant chat between your users using Pusher's reliable messaging delivery service. Using Pusher's presence channels you can show your users who is on and offline and you can carefully control security of user's messages using Pusher's authentication mechanisms.
If you don't want messages to go to your server you can use client events to send messages directly from a user to another whilst still maintaining full control over security and permissions.

Make sure your graphs reflect the latest stats by using Pusher to power your data visualisations in realtime. Pusher's server side libraries can be used to send the latest data to all your users, and our client side libraries make it easy to run code to update any visualisations with the latest data.
