Why Stream Sync Engage Matters

Applications today demand more than just alerts. Users expect intelligent, timely, context-aware interactions. SSE is built for that need.

Broadcast Engaging Notifications

Send notifications with sound and haptic feedback in real time. Target specific user segments with precision.

Push Functional Events

Toggle features, reconfigure behavior, and update app logic without requiring an app update or forcing a refresh.

Resume Missed Deliveries

When an offline client reconnects, SSE automatically delivers missed events. Define relevancy windows so events only matter when they are fresh.

In short: SSE combines power, flexibility, and reliability.

How Stream Sync Engage Works

Real-Time Pipeline with Fallbacks

When you push a notification through SSE's pipeline, it's immediately streamed to connected clients. For offline devices, SSE keeps a resync buffer and delivers missed events automatically when they reconnect.

Functional Event Channel

Send commands directly to app logic. Flip feature flags, tweak behavior, or trigger state changes without shipping new builds. Tweaking app behavior becomes as easy as sending a notification.

Relevancy Windows

Define time windows for notifications. SSE automatically expires or discards stale messages so users aren't cluttered with outdated content.

AI Agent & MCP Server

SSE's MCP Server exposes notification logic to AI agents. Build intelligent routing, personalized messaging, or context-aware delivery like suppressing messages during meetings.
