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

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.

The developers hang around in #smack (freenode, IRC) and (XMPP MUC room). Remember that it may take some time (~hours) to get a response.

You can also reach us via the Smack Support Forum if you have questions or need support, or the Smack Developers Forum if you want to discuss Smack development.


If you want to start developing for Smack and eventually contribute code back, then please have a look at the Guidelines for Smack Developers and Contributors. The guidelines also contain development quickstart instructions.
