Node-RED
Flow-based programming for IoT and automation
Node-RED is the flow-based programming platform for wiring together hardware, APIs, and online services. With 22K+ GitHub stars and backed by the OpenJS Foundation, it's the standard for IoT automation and event-driven applications. Visual programming that scales from prototypes to production.
Why Node-RED?
Building IoT applications and event-driven systems requires connecting disparate devices, protocols, and services. Traditional coding is slow for prototyping and hard for hardware teams to modify. You need a way to wire things together visually while maintaining the power to handle complex logic.
How It Works
Node-RED provides a browser-based editor where you wire together nodes to create flows. Connect MQTT for IoT devices, HTTP for APIs, databases for storage—all visually. When you need custom logic, write JavaScript in function nodes. Deploy flows to edge devices or servers.
What Is Node-RED?
Node-RED is a flow-based programming platform built on Node.js. It provides a visual editor for creating event-driven applications, 6,900+ community nodes, and deployment options from Raspberry Pi to enterprise servers. Apache 2.0 licensed.
