Jabber is significant in technology due to its role in instant messaging and presence information. It is a widely-used open-source protocol, also known as Extensible Messaging and Presence Protocol (XMPP), initially developed by the Jabber open-source community.

This technology provides a standard communication platform that can be used across applications, enabling real-time communication. Its importance lies in its open standards approach, which supports interoperability between various instant messaging systems and other communication forms like voice and video.

Furthermore, Jabber’s support of secure messaging enhances its relevance in the tech world, with its extensible design allowing developers to build and customize their applications according to specific needs. Ultimately, Jabber plays a significant role in helping organizations and individuals communicate efficiently, securely, and seamlessly on digital platforms.

DevX’s Explanation

Jabber, also known as Extensible Messaging and Presence Protocol (XMPP), is a communications protocol used primarily for instant messaging services and online presence detection. It’s a software technology that facilitates real-time, interactive communications over the internet. Its primary function is to allow for the exchange of messages and information between two points on the internet, essentially serving as a middleware for online communication. Jabber’s capabilities aren’t limited to one-on-one instant messaging.

The technology is also used in multiparty gaming, group chats, voice & video conferencing, streaming events, and broadcasting network services. This flexibility makes Jabber applicable in various domains, from corporate communication systems to social networking platforms. Apart from messaging, it allows users to share files and conduct real-time interactions, making it a versatile tool for online communication.


1. Cisco Jabber: Cisco Jabber is a popular communication application businesses use worldwide. This tool offers a range of communication features, such as video conferencing, voice calling, instant messaging, and telepresence. Users can employ it on various platforms, including Windows, Mac, iOS, and Android.

2. is an XMPP (Extensible Messaging and Presence Protocol) instant messaging service, where individuals can create free accounts to connect with friends or colleagues online. This is based on the open-source Jabber technology which promotes interoperability between different platforms.

3. Ejabberd: Ejabberd is another real-world example of Jabber technology. It is an open-source Jabber (XMPP) server written in Erlang/OTP that allows users to connect and send messages to each other. It’s widely used around the world due to its robustness, scalability, and extensibility. Some applications of Ejabberd include private instant messaging within companies, real-time news updates, and multiplayer gaming communication.
