About:
libcapn is a C library that provides a native interface for sending push notifications to Apple devices (iOS, macOS, etc.) via the Apple Push Notification service (APNs). It handles the low-level protocol communication, certificate management, and payload construction, enabling C applications to integrate push notification functionality directly.
Key Features:
  • Native C implementation for APNs communication
  • Handles SSL/TLS connection and certificate authentication with Apple's servers
  • Constructs and sends JSON payloads for notifications
  • Supports the enhanced binary protocol for reliability and speed
  • Lightweight library suitable for integration into servers and embedded systems
Use Cases:
  • Sending push notifications from a C/C++ backend server to iOS apps
  • Integrating Apple push notification support into embedded or IoT devices
  • Building custom notification gateways or middleware in C
Alternatives:
  • Houston – Ruby gem for APNs, higher-level and not a C library
  • apns2 – Go library, provides similar functionality for the Go ecosystem
  • Pushy – Java library for APNs, offers a more managed API
