Pushy is a Java library for sending push notifications via Apple's HTTP/2-based APNs protocol to iOS, macOS, and Safari devices. It supports TLS and token-based authentication, asynchronous operation, and maintains parallel connections for industrial-scale notification delivery.

Use cases

• send APNs push notifications from a Java backend
• deliver iOS push notifications at scale
• send push notifications to macOS and Safari apps
• authenticate with APNs using token-based signing keys
• test push notification sending with a mock APNs server
• build APNs notification payloads in Java

When to choose

• your backend is on the JVM and you need to send Apple push notifications
• you need high-throughput, asynchronous APNs delivery with connection pooling
• you want both TLS-certificate and token-based APNs authentication
• you need a mock APNs server for integration testing

When to avoid

• you need to send push notifications to Android (FCM) or other platforms
• you want a GUI tool for manually sending test notifications (use Pushy Console instead)
• your stack is not Java/JVM-based
