Introduction to Presence on the PubNub Data Stream Network

Who’s there? PubNub Presence knows. PubNub Presence detects when users enter and leave your app and gives the online/offline status of machines and devices connected to your app or channel. However, it does more than take user attendance. Presence also can automatically send notifications based on occupancy, can be used to trigger events based on audience size, and much more.

We also recently announced our major Presence Upgrade, adding a number of performance enhancements to our existing functionality and rolling out three new features.
