What is the MQTT Client?

An MQTT client is a device or software component that utilizes the MQTT library and connects to an MQTT Broker over the network. It facilitates the publishing and subscribing of messages in the MQTT communication protocol. The client can act as a publisher, sending messages to the broker, or as a subscriber, receiving messages from the broker. It's also possible for a client to perform both publishing and subscribing functions simultaneously.

MQTT clients can vary in form, ranging from small resource-constrained devices to full-fledged computer software with graphical user interfaces, designed for testing and development purposes. Essentially, any device or software component that establishes a connection to an MQTT service using the TCP/IP protocol can be referred to as an MQTT client.

Why does MQTTX Desktop use the UI design of chat software?

Based on the understanding of the MQTT protocol's pub/sub model, MQTTX adopts the UI design of chat software to simplify the operation logic of the interface. For example, when creating a new connection as "User A" and subscribing to a "Topic," it resembles joining a chat channel. Similarly, creating another connection as "User B" and publishing a message to the subscribed "Topic" allows "User A" to receive the message on their page. This design approach helps users quickly grasp and test MQTT-related content by emulating the communication style of chat software, which is analogous to how devices in the IoT world can utilize MQTT's pub/sub feature for inter-device communication.

Is MQTTX free?

Yes, MQTTX is completely free. It is an open-source project available under the Apache-2.0 LICENSE.
