About:
Knuff is a native macOS application designed for developers to test and debug Apple Push Notification service (APNs) integrations. It provides a straightforward graphical interface to send push notifications to iOS, iPadOS, macOS, watchOS, and tvOS devices without needing to use command-line tools. Its main value is simplifying the complex process of payload validation and certificate management for APNs.
Key Features:
  • Simple GUI for sending APNs notifications
  • Supports both token-based and certificate-based authentication
  • Built-in payload validation and formatting assistance
  • Keeps a history of sent notifications for easy reuse
Use Cases:
  • Debugging push notification delivery issues during app development
  • Testing new notification payloads and rich media before production deployment
  • Validating server-side APNs integration logic
Alternatives:
  • Pusher – Knuff is a native macOS app, while Pusher is a web-based tool that also supports FCM.
  • Postman – Knuff is specialized for APNs with a simpler UI, whereas Postman is a general-purpose API client requiring manual request configuration.
