emqttc
An Erlang MQTT client library and CLI tool supporting MQTT v5.0, v3.1.1, and v3.1.
What is emqttc?
emqtt is an open-source MQTT client library and command-line tool implemented in Erlang. It enables applications to connect to MQTT brokers for publish/subscribe messaging, supporting protocol versions 5.0, 3.1.1, and 3.1. It solves the need for a robust, protocol-compliant client in Erlang ecosystems, particularly for IoT and distributed systems.
Erlang/Elixir developers building IoT applications, real-time messaging systems, or tools that need to interact with MQTT brokers. It's also useful for DevOps engineers and testers who need a CLI for MQTT debugging and automation.
Developers choose emqtt for its native Erlang implementation, which offers reliability and concurrency benefits, full MQTT v5.0 support, and the dual utility of both a library and a CLI. Its support for multiple transports (TCP, TLS, WebSocket, QUIC) and enhanced authentication provides flexibility not found in many other clients.
