EMQX Edge is a lightweight, high-performance MQTT data backbone for the industrial edge. It connects local MQTT data, integrates with eKuiper for processing, persists selected topics with MQTT stream, and bridges data to enterprise or cloud MQTT platforms.

How is EMQX Edge different from EMQX Neuron?

EMQX Neuron connects industrial equipment through protocols such as Modbus, Siemens S7, and OPC UA, then converts its data to MQTT. EMQX Edge receives that MQTT data and brokers, processes, persists, and bridges it across the site and to the cloud.

Which MQTT versions does EMQX Edge support?

EMQX Edge supports MQTT 5.0 and MQTT 3.1.1, including all three MQTT quality of service levels (QoS 0, 1, and 2), topic aliasing, user properties, and shared subscriptions.

Can EMQX Edge operate without a cloud connection?

Yes. Local MQTT communication continues independently. Bridge caching stores configured upstream messages and retransmits them when connectivity returns, while MQTT stream can preserve selected topic data for local queries.

How does EMQX Edge differ from Mosquitto?

Both are lightweight MQTT brokers. EMQX Edge adds a multi-threaded actor architecture, built-in MQTT stream persistence and queries, eKuiper integration, MQTT over QUIC bridging, and a built-in dashboard, REST API, and Prometheus metrics for industrial edge deployments.

Where can EMQX Edge run?

EMQX Edge runs on Linux, Windows, and macOS across x86, ARM, and RISC-V architectures, with an official Docker image for container deployments.

Why EMQX Edge

Cloud-only messaging leaves the edge exposed

Edge sites need a local MQTT data backbone and reliable synchronization—even when the cloud connection drops.
