About

What it does

Node-RED is a low-code tool for connecting things. Drag nodes onto a canvas, link them together and deploy: an MQTT sensor triggers an HTTP call, a webhook writes to a database, a timer sends a message.

It runs anywhere from a Raspberry Pi to the cloud, and a huge library of community nodes covers almost every service and device.

Highlights

  • Browser-based visual flow editor
  • Thousands of community nodes
  • MQTT, HTTP, WebSocket, TCP and more built in
  • JavaScript function nodes for custom logic
  • Flows saved as JSON, easy to share and reuse

Who it's for

Makers, IoT builders and automation fans who like to see how their logic flows.
