Smack is an open source, highly modular, easy to use, XMPP client library written in Java for Java SE compatible JVMs and Android.

A pure Java library, it can be embedded into your applications to create anything from a full XMPP instant messaging client to simple XMPP integrations such as sending notification messages and presence-enabling devices. Smack and XMPP allows you to easily exchange data, in various ways e.g. fire-and-forget, publish-subscribe, between human and non-human endpoints (M2M, IoT, …).

More information are provided by the Overview.

Getting started

Start with having a look at the Documentation and the Javadoc.

Instructions on how to use Smack in your Java or Android project are provided in the Smack Readme and Upgrade Guide.


Most of Smack is governed by the Apache License 2.0 (SPDX License Identifier: Apache 2.0). This license requires that the contents of a NOTICE text file are shown "…within a display generated by the Derivative Works, if and wherever such third-party notices normally appear.".

Smack comes which such a NOTICE file. Moreover, since smack-core is licensed under the Apache License 2.0, the conditions apply to every project using Smack. The content of Smack's NOTICE file can conveniently be retrieved using Smack.getNoticeStream().

Some subprojects of Smack are governed by other licenses. Please refer to the individual subprojects.

Professional Services

Smack is a collaborative effort of many open source, professionally and spare-time, paid and unpaid, contributors. While we try to provide the best possible XMPP library for Android and Java SE compatible execution environments by following state of the art software engineering practices, the API may not always perfectly fit your requirements. We welcome contributions and encourage discussion about how Smack can be further improved. We also provide paid services ranging from XMPP/Smack related consulting to designing and developing features in order to accommodate your needs. Please contact Florian Schmaus for further information.
