Simulate 1000s of IoT devices fast - Realistic IoT data generator for MQTT, HTTP and TCP.

mer is a high-performance, developer-friendly IoT data generator written in Rust. 🦀 Stop waiting for physical hardware to test your infrastructure. Generate realistic, structured IoT payloads (MQTT, HTTP, TCP) in seconds. Key features: 🚀 Fast & Scalable: Simulate 1000s of devices with low footprint. 🛠️ Flexible: Custom Handlebars templates for any JSON schema. 🔒 Production-ready: Supports TLS, Auth, and Environment Variables. 📦 Cross-platform: Single binary, no dependencies.

"Hello Product Hunt community! 👋 I’m Kursad, a technical founder and developer deeply involved in the IoT space. Over the years, I’ve faced the same recurring bottleneck: The Hardware Gap. Whether you are building an energy monitoring platform or a smart home dashboard, you often have to wait for the physical sensors to arrive or for the firmware team to finish their work before you can test your backend at scale. I built mer (iot-data-generator) to bridge this gap. Written in Rust for maximum performance and reliability, mer allows you to simulate thousands of realistic IoT devices right from your CLI. No more messy, one-off scripts. With Handlebars templating and support for MQTT, HTTP, and TCP, you can mimic almost any sensor schema in seconds. Why I’m sharing this today: We’ve been using it internally to stress-test our ClickHouse clusters and MQTT brokers, and it saved us weeks of development time. Now, it’s open-source and ready for the world. I’d love to hear your thoughts: What protocols should we add next? (Sparkplug B? WebSockets?) How do you currently mock your IoT data? I'll be here all day to answer your questions! Happy hacking!"
