Works with the web

ejabberd supports more interaction with the browser and the web app, facilitating real-time messaging. The use of WebSockets provides the ability to seamlessly send and receive messages while a browser tab is opened. BOSH capability is provided as a fallback for XMPP connection.

Seamless and reliable mobile experience

ejabberd mobile reliability layer helps manage mobile network’s disconnection, message deliveries, consistent conversation on any online device, IoT, chat server, IM service, push notification and mobile interfaces.

Mobile network disconnections managed at XMPP server level, with contacts appearing online within the contact list. Thanks to rebind, mobile network disconnection is not managed as an end-user service disconnection
Push notifications via systems like Apple APNS or Google Notifications: if end user mobile app is not running in the foreground/background, an alert is sent each time a message is received via push feature
No message lost: for each message , the XMPP server checks the status of delivery with an acknowledgment provided by the mobile app
Carbon-copied messages: end user can read all his conversations on every device
