Node-RED - Flow-Based Programming for the Internet of Things

Node-RED is a dynamic open-source visual tool designed to wire together devices, services, and APIs. Tailored for the Internet of Things (IoT) and beyond, Node-RED's intuitive flow-based programming approach allows users to create event-driven applications by simply connecting nodes in a logical manner. Whether you're interfacing with hardware devices, integrating various web services, or creating complex data workflows, Node-RED facilitates a simplified development experience.

Built on Node.js, Node-RED offers a lightweight runtime and a rich palette of nodes that handle flows, data processing, and interactions with other services. The extensible design allows developers to create custom nodes, expanding its capabilities even further.
