General

A multi-platform, scalable push-notification engine.

Targets iOS, Android, Windows, Kindle, Baidu, etc.

Back-ends: cloud or on-premises.

Platform Notification Systems

Push notifications delivered through platform-specific infrastructures called Platform Notification Systems (PNSs).

To send a notification to all customers across the Android, iOS, and Windows versions of an app, the developer must work with Apple Push Notification Service (APNS), Firebase Cloud Messaging (FCM), and Windows Notification Service (WNS) separately.

Why Notification Hub

  • Eliminates all complexities associated with pushing notifications on your own from your app backend.
  • Support for all major push platforms.
  • Common interface to push to all platforms.
  • .NET, Node.js, Java, Python, etc.
  • Rich set of delivery patterns
    • Broadcast to one or multiple platforms
    • Push to device
    • Push to user
    • Push to segment with dynamic tags
    • Localized push
    • Silent push
    • Scheduled push
    • Direct push
    • Personalized push
