XMPP (Extensible Messaging and Presence Protocol)

XMPP (Extensible Messaging and Presence Protocol) is an open communication protocol used for real-time messaging, presence sharing, and contact management over the internet. It enables devices and applications to exchange structured messages, status updates, and notifications reliably and securely. XMPP is flexible and extensible, allowing developers to customize and add functionalities, making it suitable for instant messaging, online collaboration, and IoT applications.
