Open-source, scalable, and fault-tolerant MQTT broker able to handle 4M+ concurrent client connections, supporting at least 3M messages per second throughput per single cluster node with low latency delivery. The cluster mode supports more than 100M concurrently connected clients.
TBMQ sets a new benchmark for self-hosted MQTT brokers, proving its ability to handle one million messages per second for persistent sessions without data loss — even in the event of hardware failures. Designed to eliminate single points of failure and bottlenecks, TBMQ achieves exceptional efficiency through a combination of Redis for persistence, Kafka for message distribution, and a highly optimized broker codebase.
