Node-RED

Node-RED is a flow-based development tool for visual programming, primarily used for wiring together hardware devices, APIs, and online services. Built on Node.js, it provides a browser-based editor that enables users to create workflows by dragging and dropping nodes, which represent various functions and devices, onto a workspace. These nodes are then connected to define the data flow and processing logic. Node-RED simplifies the integration and automation of IoT systems, allowing both developers and non-developers to build complex event-driven applications with ease. It supports a wide range of protocols and services, making it a versatile tool for rapid prototyping and deployment in IoT, home automation, and industrial automation projects. Its open-source nature and extensive library of pre-built nodes contribute to its growing popularity and utility in diverse application areas.
