The world's #1MQTT platform

EMQX is purpose-built for massive scale and high availability. It supports 100M+ concurrent connections in a single cluster, processes millions of messages per second, and features a powerful built-in rule engine for real-time data processing and integration with over 50 cloud services and databases.

EMQX Enterprise is the on-premises, self-managed solution. It uses an annual subscription licensing model based on transparent and predictable capacity tiers (Sessions and TPS).

Absolutely. While EMQX powers the world's largest enterprises, our fully managed EMQX Cloud edition allows startups to start building instantly—with zero infrastructure management and a generous free tier. You only pay for what you use as you scale.

EMQX integrates with AI agents through native Agent-to-Agent (A2A) support over MQTT. It serves as a high-performance, real-time data backbone, enabling seamless bidirectional communication between physical IoT devices and AI agents.

EMQX Neuron serves as a lightweight industrial gateway that converts 100+ OT protocols (such as Modbus, OPC UA, and Siemens S7) into standard MQTT. Together with EMQX, it provides a unified connectivity layer that bridges real-time data from factory floor devices to IT systems, cloud platforms, and AI pipelines.

Migrating is straightforward. EMQX is 100% compliant with MQTT 3.1, 3.1.1, and 5.0 standards, meaning your existing devices and client applications will connect without any code changes. Our team also provides comprehensive migration guides and enterprise support to ensure a seamless transition.
