hivemq-mqtt-web-client
A websockets-based MQTT client that runs directly in your browser for publishing and subscribing to MQTT messages.
What is hivemq-mqtt-web-client?
HiveMQ MQTT Web Client is a browser-based application that enables users to connect to MQTT brokers via WebSockets for publishing and subscribing to messages. It provides a simple interface for real-time communication without requiring native software, making it useful for testing and development. The tool supports connections to local brokers, network brokers, and public MQTT servers.
Developers and IoT engineers who need to test, debug, or demonstrate MQTT-over-WebSocket applications directly from a browser. It’s also suitable for educators and hobbyists working with MQTT messaging.
It offers a lightweight, no-install solution for interacting with MQTT brokers, with simultaneous publish/subscribe capabilities and compatibility with modern browsers. Its simplicity and embeddability make it a convenient tool for rapid development and integration.
Overview
A websockets based MQTT Client for your browser.
Use Cases
Best For
- Testing MQTT-over-WebSocket implementations during development
- Debugging real-time messaging flows in IoT projects
- Demonstrating MQTT publish/subscribe functionality in presentations
- Connecting to local or network MQTT brokers without installing software
- Quickly prototyping MQTT applications in a browser environment
- Educational purposes for learning MQTT protocol basics
Not Ideal For
- Production environments requiring robust security, authentication, and audit logging features

- Teams seeking a highly customizable or white-labeled client interface without attribution requirements
- Environments with legacy browser support, such as Internet Explorer versions below 10
Pros & Cons
Pros
Enables direct MQTT communication via WebSockets in any modern browser, eliminating the need for native apps, as highlighted in the README's focus on websocket support.
Allows users to publish messages and subscribe to topics concurrently in the same interface, streamlining development and testing workflows, which is a core feature mentioned.
Supports connections to localhost, network brokers, and public MQTT servers like HiveMQ's broker on port 8000, making it versatile for various testing scenarios.
Can be integrated into other software projects with attribution, providing a quick way to add MQTT functionality without building from scratch, as noted in the README.
Cons
Focuses on basic publish/subscribe without support for advanced MQTT features like QoS levels, retained messages, or will messages, which are essential for production-grade applications.
Requires modern browsers with WebSocket support and does not work with Internet Explorer versions below 10, limiting its use in older or restricted environments as admitted in the README.
As a straightforward tool, it offers limited options for UI customization or branding, requiring significant source code modifications for tailored interfaces.
