What is n8n?

n8n (pronounced "nodemation") is a visual workflow automation platform. Think of it as a digital assembly line: you connect different apps and services like building blocks, and n8n runs the pipeline automatically. No coding required.

Why n8n?

You might be wondering: why n8n and not Zapier or Make? Here's the comparison:

Feature	n8n	Zapier	Make
Pricing	Free tier (self-hosted) or affordable cloud	Expensive ($29+/mo for basics)	Moderate ($9+/mo)
Flexibility	Extremely flexible, custom code nodes	Limited to pre-built integrations	Good but less flexible
Self-hosting	Yes — full data control	No	No
AI integration	Built-in AI nodes (Claude, GPT)	Limited AI support	Some AI modules
Complexity	Handles complex multi-branch workflows	Simple linear workflows	Moderate complexity

Core Concepts

n8n workflows are built from three components:

Triggers — what starts the workflow. Examples: schedule (every day at 8 AM), webhook (when someone submits a form), email (when a new message arrives)
Nodes — processing steps. Each node does one thing: read a spreadsheet, send an email, call an API, process text with AI
Connections — arrows between nodes that define the data flow

Getting Started

Option 1: n8n Cloud — Sign up at n8n.io. Free tier includes 5 active workflows. Best for beginners.

Option 2: Self-hosted — Run n8n on your own server via Docker. Free forever, unlimited workflows. Requires basic server knowledge.

# Self-hosted with Docker (one command)
docker run -it --rm --name n8n -p 5678:5678 n8nio/n8n

Once running, open http://localhost:5678 and you'll see the visual editor — a canvas where you drag, drop, and connect nodes.

Your First Workflow in 5 Minutes

Click "Add workflow"
Add a Schedule trigger (set to daily at 8:00 AM)
Add a Google Sheets node (read data from a spreadsheet)
Add an Email node (send the data as a formatted report)
Connect them: Schedule → Sheets → Email
Click "Execute" to test, then "Activate" to run daily

That's it. You've built your first automation. No code, no programming, no technical degree needed.

For a real-world example of n8n in action, see how we automated our entire SEO pipeline.

n8n turns "I wish this happened automatically" into "it does happen automatically." The visual interface means you can see exactly what your automation does — and change it in seconds.
