MQTT.js is a JavaScript client library and asynchronous messaging client used to connect to message brokers and exchange data via the MQTT protocol. It provides a broker interface for publishing and subscribing to topics, and includes a command-line interface for interacting with brokers without writing code. The library supports multiple network layers, including TCP, TLS, and WebSockets, and allows for custom WebSocket construction and transport injection to handle specific headers or subprotocols. It implements bandwidth reduction through topic aliasing, which replaces repetitive topic str
libhv is a high-performance C/C++ network library and event-driven I/O framework used to build TCP, UDP, SSL, HTTP, WebSocket, and MQTT clients and servers. It provides a non-blocking event loop for managing network sockets, timers, and system signals across multiple threads. The project is distinguished by its integrated support for specialized network roles, including a full HTTP web server with RESTful routing and middleware, an MQTT messaging client for IoT communication, and the ability to implement SOCKS5 and HTTP proxies. It also features a reliable UDP implementation to ensure ordered
MQTTX is a cross-platform MQTT client application designed for testing, debugging, and managing MQTT brokers. It supports both MQTT v3.1.1 and v5.0, enables simultaneous management of multiple broker connections, and provides an interactive chat-style interface for publishing and subscribing with configurable quality of service, payload transformation, and topic visualization. The client can be used as a desktop application, a command-line tool, or a self-hosted web client deployable via Docker. What sets MQTTX apart is its integration of AI-assisted workflows, allowing users to generate MQTT
