MAXS (Modular Android XMPP Suite), a set of open-source GPLv3 licensed Android applications, allows you to control your Android device and receive notifications over XMPP. For example, you can compose and send a SMS message on your desktop/laptop by sending a command message from every standard compliant XMPP client to MAXS running on your smartphone.

MAXS is dedicated to users privacy and choice, that is why it's designed modular. This means that the functionality is split across components, which are standard Android applications. These components can be categorized in three types: Modules, Transports and the main component. Modules provide the notifications and commands, which are exchanged between MAXS and the user over so called transports. MAXS modules and transports are glued together with the so called MAXS main application.
