Realtime MQTT Broker
The EMQX/HiveMQ/AWS IoT alternative: a real MQTT broker (pub/sub, wildcards, retained, QoS 0/1/2, sessions) carried over WebSocket — PLUS your Air Pipe pipeline runs on every interface-shaped message (validate, enrich, store, republish). One vendor for transport, logic, auth and billing.
Realtime MQTT Public Stream
Open MQTT: clients connect with NO username or password and subscribe to a public topic for live data (sensors, transit, prices, status). EMQX/HiveMQ allow_anonymous model, but multi-tenant-safe — anonymous reaches only public interfaces, never private topics — and your pipeline runs on the public stream.
