MQTT Gateway Load Test Simulator

Designed for IoT developers and QA engineers, this simulator generates realistic, high-concurrency MQTT traffic to stress test gateways and brokers. You can manage device credentials in batches and define flexible messaging patterns—including payload size and send frequency—to mimic real-world scenarios. Live dashboards display throughput, latency, and success rates, providing immediate insight into system limits. The tool's portable nature means you can run it directly on Windows without complex installation, making it an ideal solution for pre-deployment validation of platforms like ThingsBoard.
