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
