What it does
Node-RED's goal is to enable anyone to build applications that collect, transform and visualize their data; building flows that can automate their world. Its low-code nature makes it accessible to users of any background, whether for home automation, industrial control systems or anything in between. From home hobbyists to large scale industrial operations, Node-RED has found a place in a wide range of applications, supported by an active community that has built over 5,000 Nodes and Flows to help you get started quickly. Node-RED is built on Node.js, taking full advantage of its event-driven, non-blocking model. This makes it ideal to run at the edge of the network on low-cost hardware…from nodered.org
