Node-RED is a visual tool for wiring together hardware devices, APIs and online services in new and interesting ways.
Browser-based flow editing
Built on Node.js
The light-weight runtime 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 such as the Raspberry Pi as well as in the cloud.
The flows created in NodeRED are stored using JSON which can be easily imported and exported for sharing with others.
