Libstrophe is a minimal XMPP library written in C. It has almost no external dependencies, only an XML parsing library (expat or libxml are both supported).

This module implements support for a group of push notification extensions by the Tigase team that allow a client to specify filters to be applied to push notifications. It is a custom extension to XEP-0357: Push Notifications.

This module implements XEP-0357: Push Notifications.

Some platforms, notably Apple’s iOS and many versions of Android, impose limits that prevent applications from running or accessing the network in the background. This makes it difficult or impossible for an XMPP application to remain reliably connected to a server to receive messages.

In order for messaging and other apps to receive notifications, the OS vendors run proprietary servers that their OS maintains a permanent connection to in the background. Then they provide APIs to application developers that allow sending notifications to specific devices via those servers.

When you connect to your server with a client that requires push notifications, it will use this module to set up a “push registration”. When you receive a message but your device is not connected to the server, this module will generate a notification and send it to the push gateway operated by your application’s developers). Their gateway will then connect to your device’s OS vendor and ask them to forward the notification to your device. When your device receives the notification, it will display it or wake up the app so it can connect to XMPP and receive any pending messages.

Dino is a chat client for the desktop. It focuses on providing a minimal yet reliable Jabber/XMPP experience and having encryption enabled by default.
