# CometD

Unclassified · [Official website](https://cometd.org)

CometD is an open-source framework for real-time web messaging that implements the Bayeux protocol. It provides a Java server and JavaScript clients so a site can push data to browsers over WebSocket or HTTP long-polling, for example for live updates or chat. CometD may use a browser cookie to keep track of the client session.
