Built for the Edge
Blazing-Fast
Optimized for edge with low latency and high throughput—up to 10x faster than Mosquitto when running on multi-core CPUs.
Ultra-Lightweight
Minimal footprint with efficient resource utilization, perfect for edge devices. Boot memory footprint is as low as 200KB.
Cross-Platform
Runs seamlessly on multiple operating systems and hardware architectures, including Linux, Windows, ARM, x86, and RISC-V.
How EMQX Edge Works
IoT Data Hub at the Edge
EMQX Edge acts as the central data hub for a local site, factory, or facility. It aggregates data from all local devices (via Neuron or Kepware etc) and bridges it to the cloud.
Connect
Receives MQTT data from local devices or gateways like EMQX Neuron.
Process
coming soonUses its rule engine to filter, transform, and route data locally.
Bridge
Publishes data via a secure, reliable MQTT bridge to a central cloud broker.

Edge Computing
Your Lightweight Edge MQTT Broker
EMQX Edge is a full-featured MQTT broker that runs on-premise, handling local device communication and bridging critical data to the cloud.
Lightweight MQTT Brokering
Provides a full-featured MQTT 5.0 broker at the edge. Manage device-to-device communication, data streams, and local topic trees autonomously.
- Full MQTT 5.0 & 3.1.1 Support
- 100K+ Connections on a Single Node
- Runs on x86, ARM, and in Docker
Real-Time Data Processing
Use the SQL-based rule engine to process data in real-time. Filter noise, aggregate values, and transform data formats locally before bridging to the cloud.
- Intuitive SQL-like Syntax
- Trigger Local Actions & Alerts
- Reduce Cloud Data Costs
Seamless Cloud Bridging
Securely bridge selected data to any cloud platform. Synchronizes edge data with your central IT systems for a unified view and ensures data is never lost, even with unstable networks.
- Bi-directional Bridge to EMQX Cloud
- Connect to AWS IoT, Azure IoT Hub, etc.
- Automatic Buffering & Re-transmission
OPC UA & MQTT Integration
Combine the power of industrial protocols with MQTT. EMQX Edge acts as a local hub, receiving standardized MQTT data from OPC UA and Modbus (via Neuron) and bridging it to any MQTT platform.
- Integrate OPC UA & Modbus
- Aggregate edge data with MQTT
- Unified data model for IT/OT
Edge AI/ML Integration
Feed processed edge data directly into local AI/ML models. EMQX Edge's rule engine can trigger inference and publish results back via MQTT for real-time decision-making.
- Low-latency inference at the edge
- Real-time anomaly detection
- Optimize predictive maintenance models
Unified Namespace
Unified Namespace: Edge to Cloud
Seamlessly Integrate EMQX Neuron, Edge, and Cloud to build a unified namespace (UNS) architecture for your industrial data, enabling true IT/OT convergence.
Unified Namespace
Edge to cloud topic space
Device Layer
Normalize OT data into MQTT topics at the edge.
Local pub/sub, buffering, and secure northbound bridge.
Scale globally with managed MQTT and data services.
Built for the Industrial Edge
EMQX Edge provides a robust, scalable, and secure broker for your edge to edge, and edge to cloud data pipeline.
Full MQTT 5.0 Support
Leverage the full power of MQTT 5.0, including shared subscriptions, topic aliases, and user properties etc.
Persistent Cloud Bridge
Reliably bridge data to any MQTT IoT platforms. Automatic store and forward capabilities for unstable network.
Powerful Data Processing
Use SQL-like engine to quickly perform real-time data filtering, transformation, and routing (coming soon).
High-Availability Clustering
Cluster two or more Edge nodes to create a highly available deployment for critical on-premise workloads.
Enterprise-Grade Security
Secure your edge data with TLS/SSL encryption, plus multiple authentication methods (username and password, JWT).
Cross-Platform Support
Deploy easily on x86 or ARM architectures, with support for Linux, Windows, macOS, and Docker.
Easy Observability
A built-in dashboard, view logs, and capabilities of exporting metrics to Prometheus etc.
REST API Management
Automate and manage your edge deployments at scale using a comprehensive REST API for configuration and monitoring.
Process Data with a SQL-Based Rule Engine
Filter, transform, and route data locally with an intuitive SQL language, without writing complex code.
Powering Edge Industrial Scenarios
See how EMQX Edge is used across leading industries to manage edge data.
Factory Floor Data Hub
Deploy EMQX Edge as a local data hub on the factory floor. It aggregates data from multiple EMQX Neuron instances, manages local device communication, and bridges critical OEE data to the central MES/SCADA system.
In-Vehicle Data Processing (T-BOX)
Run EMQX Edge on in-vehicle T-BOX units. It collects CAN bus data (via Edge extension), processes it in real-time for driver alerts, and uses the persistent bridge to send critical telematics to the cloud platform for fleet management.
Smart Utility Data Aggregation
Install EMQX Edge on local data concentrators or gateways for smart meters, solar farms, or charging stations. It manages thousands of local device connections and securely bridges aggregated data to the central platform.
