Spark (XMPP client)


Spark is an open-source instant messaging program that allows users to communicate via text in real time. It can be integrated with the Openfire server to provide additional features, such as controlling various parts of Spark functionality from a central management console, or integrating with a customer support service Fastpath, allowing Spark users to log into queues, accept and forward support requests, use canned responses. Being a cross-platform application, it can be run on various systems. Installers for Windows, macOS and Linux are available on the official website.

History

Previously known as Jive Communicator, it was designed by Jive Software with business usage in mind, with a lightweight graphical design and simplistic user interface. Later, it was open-sourced and donated to the Ignite Realtime community, along with Openfire, for further improvement and development.

Features

Spark is based on a popular open-source Smack API library, also developed by Ignite Realtime. It has a tabbed interface for managing conversations, a quick and full history, and a robust search inside the contacts window, which is designed for organizations with many units and employees. Other features include shortcuts to access recent and favorite contacts, and Spark supports ad-hoc and regular group chats. Like most modern IM clients, Spark supports SSL/TLS encryption, and additionally provides an option to use Off-the-Record Messaging for end-to-end encryption. Though it is designed to work with XMPP servers, it can also integrate with Kraken IM Gateway plugin for Openfire, and provide an option to connect with various other IM networks.
