• Self-Hosted Infrastructure - Provides a private messaging server for managing real-time alerts and message persistence.
• Push & Notifications - Standardises mobile notification delivery by acting as a gateway between self-hosted messaging servers and native operating system push services.
• Pub-Sub Systems - Listens for incoming messages on specific channels to trigger scripts.
• Message Caching Services - Stores incoming notifications in a relational database to allow clients to retrieve historical messages after reconnecting.
• Streaming Protocols - Receives real-time updates using persistent connections for live delivery.
