Frequently asked questions
Find quick answers to common questions about EMQX and IoT.
An MQTT broker is a server that receives all messages from the clients and then routes the messages to the appropriate destination clients. It acts as the central hub in a publish-subscribe messaging system.
EMQX is a highly scalable, distributed MQTT broker built for the largest IoT deployments. Its key features include massive scalability (100M+ concurrent connections), high-availability, robust security features, and powerful data integration capabilities, making it a reliable and powerful choice for mission-critical applications.
MQTT 5.0 is the latest version of the protocol, introducing several major improvements over 3.1.1, including enhanced error reporting, new message features (like shared subscriptions and message expiry), and improved authentication mechanisms. While EMQX supports both, we recommend using MQTT 5.0 for new projects to leverage these advanced features.
You can start with our open-source version, which is completely free to use. For enterprise-grade features, cloud deployment, and dedicated support, you can sign up for a free trial of EMQX Cloud or contact our sales team for a demo of EMQX Enterprise.
