Coreflux handles it all in one place. **Get** data from devices, **centralize** it in your broker, **process** it with simple scripts, and **send** it wherever it needs to go. **"You can do a LoT"** - The complete IoT data pipeline for developers who want to ship faster. ## Quick Navigation Go from zero to your first LoT Action in under 5 minutes. Install Coreflux on Windows, Linux, Docker, or ARM. Manage your broker from the browser—explore topics, edit LoT, configure routes. Learn the Language of Things - Actions, Models, Rules, and Routes. Download Coreflux MQTT Broker - free self-hosted version available. ## What is LoT? Think of LoT as **SQL for real-time IoT data**. **Just like SQL lets you query databases without writing low-level code**, LoT lets you process MQTT messages without deploying external services. Write simple scripts, get instant results. Instead of deploying separate microservices to process, transform, and route your IoT data, write simple scripts that run inside the broker. No containers to orchestrate. No message queues to manage. Just logic that executes the moment data arrives. Learn the fundamentals of the Language of Things and how it works. React to events and publish data. "When temperature exceeds 80°, send an alert." Transform and structure data. Convert raw bytes to clean JSON with context. Connect systems. Stream data to PostgreSQL, MongoDB, REST APIs, and more. ## Why Developers Choose Coreflux No microservices, containers, or orchestration for basic automation. One binary, full functionality. Logic executes on publish, not on poll. Sub-millisecond response times. Everything runs inside the MQTT broker. No Redis, no Kafka, no Node.js. Write automation in plain English-like syntax anyone can understand. *** Ready to see what this looks like? Here's a working example you can deploy in seconds. ## See It In Action **The problem:** You want to see your broker run logic at the edge without external hardware or sensors. **The solution:** A temperature simulator action that publishes readings every 5 seconds—deploy it and see data on a topic right away: ```lot theme={null} DEFINE ACTION TemperatureSimulator ON EVERY 5 SECONDS DO PUBLISH TOPIC "sensors/zone1/temperature" WITH "{\"temperature\": 72}" ``` This action runs every 5 seconds and publishes a JSON temperature reading to `sensors/zone1/temperature`. Subscribe to that topic with MQTT Explorer or any MQTT client to see output immediately after deployment. *** ## Resources Explore examples and community projects.
