Jabber

Jabber is an open-source protocol used for instant messaging and real-time communication over the internet. It allows individuals and organizations to send text messages, share files, and have voice or video chats using compatible software. Unlike proprietary messaging services, Jabber (also known as XMPP) offers flexibility, security, and control, as users can set up their own servers or connect to existing ones. It’s commonly used in professional environments for secure internal communications and in applications that prioritize privacy and customizability.
