Live Industrial MQTT Broker Simulator & OPC UA Telemetry Visualizer

Interactive browser-based MQTT simulation and OPC UA test bench powered by Eclipse Mosquitto WebSocket (WSS) and a real opcua2mqtt Rust edge daemon.

What You Can Test in This Live MQTT Simulator

• Real-Time OPC UA to Mosquitto MQTT Streaming: Connect to a live OPC UA PLC simulator (opc.tcp://opc-ua-sim:49947) and inspect JSON and Sparkplug B payloads in real time.
• Air-Gapped & Local Mosquitto Broker Blueprints: Copy production-ready config.toml and docker-compose.yml files for local Mosquitto, EMQX, or HiveMQ deployments.
• Store & Forward Failure Simulation: Observe how the embedded disk Write-Ahead Log (WAL) buffers telemetry during broker disconnects and replays with zero data loss.
