Node-RED

Flow-based programming for wiring together hardware, APIs and services.

Node-RED is a flow-based, low-code development tool from the OpenJS Foundation for visually wiring together devices, APIs, and online services in a browser-based editor. Flows are built by dragging nodes onto a canvas and connecting them, with a huge community library of nodes and the ability to deploy flows to a lightweight Node.js runtime. It is a de facto standard in IoT and event-driven integration.
