Built for the AI Era
From autonomous agents to IoT sensors, CloudSignal handles real-time messaging at any scale
The Protocol Built for Real-Time
HTTP wasn't designed for real-time. WebSockets are complex. MQTT is purpose-built for efficient, reliable messaging.
Pub/Sub Architecture
Decouple producers and consumers. Agents publish to topics without knowing who subscribes. Perfect for dynamic, evolving multi-agent systems.
Sub-100ms Latency
Purpose-built for real-time. MQTT's binary protocol and persistent connections deliver messages faster than HTTP polling or webhooks.
Works Offline
QoS levels ensure message delivery even when connections drop. Messages queue and deliver when agents reconnect.
Secure by Design
TLS encryption, topic-level ACLs, and authentication ensure only authorized agents can publish or subscribe to sensitive topics.
Massive Scale
Handle millions of concurrent connections. The same protocol that powers industrial IoT now powering your AI infrastructure.
Retained Messages
New agents instantly receive the latest state when they subscribe. No need to request historical data or wait for updates.
