What is Node RED

A visual tool for wiring the Internet of Things. It allows you to wire together hardware devices, APIs and online services in new and interesting ways.


Browser-based flow editing
Node-RED provides a browser-based flow editor that makes it easy to wire together flows using the wide range nodes in the palette. Flows can be then deployed to the runtime in a single-click. JavaScript functions can be created within the editor using the a rich text editor. A built-in library allows you to save useful functions, templates or flows for re-use.

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.

Social Development
The flows created in Node-RED are stored using JSON which can be easily imported and exported for sharing with others. An online flow library allows you to share your best flows with the world.
