Thousands of devices send telemetry data via WebSocket. Server-side auth per device, per-topic authorization, and rate limiting to prevent abuse. Heartbeats and reconnection with backoff for unstable network.

Basic real-time features (e.g., limited chats or dashboards) are free. Premium unlocks higher connection limits, priority support, and advanced analytics. Revenue from monthly subscriptions.

Charge per connection minute or per message. Ideal for IoT platforms where device count varies. Revenue scales with customer usage.
