## What it is
The Eclipse Paho MQTT 3.1/3.1.1 client library for Go, enabling applications to connect to an MQTT broker to publish messages and subscribe to topics. It supports fully asynchronous operation and MQTT over websockets.

## Use cases
- connect a Go application to an MQTT broker
- publish and subscribe to MQTT topics in Go
- build IoT device messaging in Go
- use MQTT over websockets from Go
- receive sensor data via MQTT subscriptions

## When to choose
- you need a mature, widely used MQTT 3.1/3.1.1 client in Go
- you need asynchronous publish/subscribe or websocket transport support

## When to avoid
- you need MQTT v5 support - use the newer eclipse/paho.golang client instead

## Facets
- artifact type: library
- maturity: maintenance
- function: message-queue, http-client, websocket, sdk
- domain: iot, developer-tools
- platform: go, cross-platform
- tags: mqtt, mqtt-client, pubsub, eclipse-paho, iot-protocols, messaging
