Node-RED

Basic Information

Product Description

Node-RED is a browser-based flow programming tool originally developed by IBM and now a project of the OpenJS Foundation. It provides a visual flow editor where users can connect hardware devices, APIs, and online services by dragging and dropping nodes. Its lightweight runtime is built on Node.js, allowing it to run on low-power devices like Raspberry Pi as well as in the cloud.

Core Features/Characteristics

• Browser-based Flow Editor: Drag-and-drop visual flow design
• 5,000+ Node Library: Rich ecosystem of community-contributed nodes
• One-click Deployment: Deploy designed flows to the runtime with a single click
• Node.js Runtime: Lightweight event-driven non-blocking model
• Edge to Cloud: Can run anywhere from Raspberry Pi to the cloud
• State Management: Supports flow-level, global-level, and node-level context state management
• Persistent Storage: Supports persistence in memory, file systems, or databases like Redis
• Templates and Functions: Built-in library for saving and reusing flows, functions, and templates
• IoT-Friendly: Particularly suitable for IoT scenarios

Relationship with OpenClaw Ecosystem

As a flow programming tool, Node-RED can serve as one of the workflow execution engines for OpenClaw agents, especially in IoT and smart home scenarios. OpenClaw can connect various IoT devices and hardware through Node-RED, expanding the agent's control over the physical world. Node-RED's "edge operation" feature aligns with OpenClaw's "local operation" philosophy. The two naturally synergize within the Home Assistant ecosystem—OpenClaw handles AI decision-making, Node-RED manages flow execution, and Home Assistant controls devices.
