I'm passionate about building intelligent systems that bring comfort, efficiency, and smart control to daily life. With hands-on experience in IoT devices, AI integration, and educational content creation, I specialize in developing smart home solutions that bridge the physical and digital worlds.

MQTT Public Broker(Free Test Server)

I have deployed a public MQTT broker on my personal VPS, containerized with Docker. By making this broker publicly available, I aim to provide a simple playground for developers, students, and IoT enthusiasts who want to experiment with MQTT without the hassle of setting up their own environment.

Why I Built This Broker

There are several reasons behind this project:

  • Contributing to the community by offering a free broker for testing and learning.
  • Demonstrating real-world use cases of MQTT in IoT and machine-to-machine communication.
  • Creating a foundation for future tutorials and technical deep dives.

A Quick Look at MQTT

MQTT (Message Queuing Telemetry Transport) is a lightweight messaging protocol designed for machine-to-machine (M2M) communication.

Key Applications of MQTT

  • IoT devices such as sensors, wearables, and smart home systems.
  • Real-time applications where low bandwidth and reliability are critical.
  • Prototyping and testing new ideas quickly and efficiently.

In short, MQTT makes it easy for devices to talk to each other in a simple, efficient, and scalable way.

Notes

  • This broker is intended for testing and learning only.
  • Please avoid heavy traffic or production use.

How You Can Use It

This broker is open for testing and educational purposes. You can connect, publish, and subscribe to topics to explore how MQTT works in practice. It’s a great way to try out IoT scenarios, validate your applications, or simply learn the basics of the protocol.

If you ever need your own dedicated MQTT broker running on your domain and server — fully customized, secure, and production-ready — I’d be happy to help you set it up.
