n8n (pronounced “n-eight-n”, a numeronym of “nodemation”) is a workflow automation platform that connects apps, APIs, and services through a visual, node-based editor. It is developed by a German software company and is described as “fair-code” — the source code is available on GitHub, but with licensing terms that restrict certain commercial uses. n8n supports both cloud-hosted and self-hosted deployments and offers a large library of built-in integrations.

n8n runs as a self-hosted service on one of the lab RPi servers. It is used for home automation workflows, monitoring, and triage — including walking the dependsOn graph when a device fails. See [N8N system](30-Systems/Home Automation/N8N/index.md) for the local deployment and n8n service for how it is used.
