Real-time Sync (SSE / WebSocket)

Server-Sent Events broadcasts for one-way updates (dashboard live numbers, feature-flag changes), with WebSocket fallback for bidirectional needs (collaborative editing, presence). Backed by Laravel Reverb, Soketi, or a stateless Redis pub/sub depending on connection volume.

2 projects and 17 packages carry this capability.
