Open Source MQTT Brokers
summary
Survey of open source MQTT brokers compares concrete features and deployments: Mosquitto is lightweight and recommended for home automation, includes CLI clients and runs on Linux with optional WebSockets; EMQ supports MQTT 5.0 and QoS 2 for large-scale systems; VerneMQ and RabbitMQ/ActiveMQ offer multi-protocol flexibility; Eclipse Paho supplies client libraries in many languages. Notes that most projects rely heavily on a few maintainers and run best on Linux. A simple HTML5 page + Paho JS + Mosquitto WebSockets demo works after minor setup.
