Node-RED
also: Node RED · flow-based programming
Open-source, flow-based programming tool for wiring together devices, APIs, and services in a browser; popular for IoT gateways and quick integrations.
Node-RED, built on Node.js and hosted by the OpenJS Foundation, lets users connect nodes for MQTT, Modbus, HTTP, databases, and dashboards into flows edited in a web browser. It runs on small single-board computers, gateways, servers, and industrial edge devices, and is widely used to prototype integrations and run lightweight edge logic.
Where it bites: large flows become hard to review and version, community nodes vary in quality, an exposed editor is a security risk, and it is not a real-time control system.
Outside help is worth it for turning prototype flows into maintainable services, securing deployments, and building gateway logic for MQTT and Modbus.
Common requests
- Gateway flows for MQTT, Modbus, and HTTP

Founder takeaway
Keep Node-RED flows in version control and never expose the editor to the internet without authentication.
