VerneMQ is a high-performance, distributed MQTT message broker built on Erlang/OTP with master-less clustering for horizontal scalability and fault tolerance. It targets IoT platforms, smart products, and mobile messaging with support for MQTT 5, websockets, plugins, and enterprise-grade operations.
Use cases
- run a scalable mqtt broker for iot devices
- connect millions of concurrent mqtt clients
- cluster mqtt brokers for high availability
- mobile push messaging with pub/sub
- industrial iot middleware for manufacturing
- bridge mqtt between sites
- monitor and control field devices over mqtt
When to choose
- you need a battle-tested, horizontally scalable MQTT broker with master-less clustering
- you need MQTT 5, websockets, shared subscriptions, and plugin extensibility (Lua, Erlang, webhooks)
- you run industrial or telecom-grade workloads requiring continuous operation and fault tolerance
When to avoid
- you need a lightweight single-node broker for a small hobby project
- your team cannot operate Erlang-based systems or prefers brokers in more common languages
- you need Kafka-style persistent log/streaming semantics rather than MQTT pub/sub
