+== Application: Websocket Clients (Echo and Console)
+
+**Status: Production**
+
+The application launcher also provides a Websocket echo client and a Websocket console client.
+The echo client connects to APEX and prints all events it receives from APEX.
+The console client connects to APEX, reads input from the command line, and sends this input as events to APEX.

+# $APEX_HOME/bin/apexApps.sh ws-echo [args]
+# $APEX_HOME/bin/apexApps.sh ws-console [args]

+|====================
+
+The arguments are the same for both applications:
+
+- `-p` defines the Websocket port to connect to (defaults to `8887`)
+- `-s` defines the host on which a Websocket server is running (defaults to `localhost`)
+
+A discussion on how to use these two applications to build an APEX system is detailed HowTo-Websockets.
