Narwhal
An extensible pub/sub messaging server for edge applications that delegates authentication and business logic to external modulators.
What is Narwhal?
Narwhal is an extensible pub/sub messaging server built for edge applications that need real-time communication. It solves the problem of choosing between overly complex XMPP servers and rigid MQTT brokers by providing a lightweight core that delegates authentication, authorization, and business logic to external services called modulators. This allows developers to implement custom application logic without modifying the messaging server itself.
Developers building real-time features like chat, notifications, or device communication for mobile, desktop, or IoT applications who need a flexible, high-performance messaging backend. It's particularly suitable for teams wanting to avoid the complexity of XMPP or the limitations of standard MQTT brokers.
Developers choose Narwhal because it offers the performance of an edge-optimized broker with the flexibility to implement custom application logic through external modulators. Unlike traditional brokers that require complex plugins or sidecar services, Narwhal cleanly separates messaging routing from business logic, making it easier to adapt to specific use cases while maintaining high throughput.
