TBMQ Professional Edition is the commercial MQTT broker built by the ThingsBoard team for large-scale IoT:
scalable, fault-tolerant and durable messaging for millions of MQTT 3.x and 5.0 clients. It runs the same masterless,
Kafka-backed cluster as the Community Edition — measured at 100M+ concurrent connections and 3M+ messages per second —
and adds what production teams need on top: OAuth 2.0 single sign-on, role-based access control, audit logs, domain
management, white labeling and a managed Private Cloud.
Start with the public demo broker below, then continue to the architecture, installation, security and client
management sections.
