What Is n8n and When Should You Use It?

n8n is an open‑source workflow automation platform. It lets you connect APIs, databases, and tools into visual workflows—ideal for AI pipelines, back‑office automation, and prototypes where you don’t want to write a full backend.

You should consider n8n when:

• You want to automate multi‑step processes across tools.
• You need to orchestrate AI calls (LLMs, embeddings, scoring).
• Your team prefers low‑code workflows over heavy custom code.
• You need the option to self‑host for data privacy.

The Automation pillar page shows how n8n fits with AI testing, monitoring, and Google Sheets pipelines.
