Node-RED is a tool for wiring together hardware devices, APIs and online services in new and interesting ways.
For Linux/OS X, if you already have Node.js installed, run:
$ sudo npm install -g node-red $ node-red
Otherwise, head over to the Getting Started guide.
Already got Node-RED installed and wonder where the download button has gone? Head over to the Upgrading guide.
Latest version: v0.14.3 (npm)
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.
A built-in library allows you to save useful functions, templates or flows for re-use.
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.
With over 225,000 modules in Node's package repository, it is easy to extend the range of palette nodes to add new capabilities.
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.
