A flow-based programming tool for collecting, transforming, and visualizing real-time IoT and automation data.
About the Project
Why use this?
Node-RED lets engineers connect devices, APIs, databases, and services through visual event-driven flows. Its browser-based editor makes it easy to wire MQTT topics, HTTP endpoints, serial devices, databases, and cloud services into automation logic without writing extensive boilerplate.
It is a strong choice for IoT edge applications, industrial control, home automation, and rapid prototyping. Node-RED runs on low-cost edge hardware such as Raspberry Pi as well as in the cloud, and its community provides more than 5,000 nodes and flows for common integrations. [92]
