nodered

Flow-based development tool for visual programming, originally developed by IBM for wiring together hardware devices, APIs, and online services as part of the Internet of Things. It provides a browser-based editor that makes it easy to wire together flows using a wide range of nodes in the palette that can be deployed to its runtime in a single click, offering extensive customization and integration capabilities. Node-RED is particularly useful for developers and engineers working on IoT projects, automation, and rapid prototyping.
