What is n8n? The Ultimate Guide to Workflow Automation 2025
What is n8n? It’s the fair-code workflow automation tool that’s taking the tech world by storm. Unlike traditional platforms, n8n (nodemation) gives you full control over your data and infinite flexibility through its node-based architecture.
Understanding n8n: The Basics
At its core, n8n is a workflow automation platform that allows you to connect different apps and services together. It uses a visual, flowchart-like interface where you connect “nodes” to build complex automations.
💡 Key Difference: While tools like Zapier are linear, n8n allows for branching, looping, and complex logic, making it more akin to visual programming.

How to use n8n for Automation
Learning what is n8n and how to use it starts with understanding its three main components:
1. Workflows
A workflow is your automation canvas. It flows from a Trigger (start) to various Actions (steps).
2. Nodes
Nodes are the building blocks. There are two types:
- Regular Nodes: Perform actions (e.g., “Send Slack Message”, “Add Row to Google Sheets”)
- Core Nodes: Control logic (e.g., “If/Else”, “Merge”, “Split In Batches”)
3. Connections (Credentials)
Securely store your API keys and passwords for the services you connect.
Example Workflow: Social Media Auto-Poster
- Trigger: RSS Feed Read (New blog post detected)
- Action: OpenAI (Summarize article)
- Action: Twitter (Post summary with link)
- Action: LinkedIn (Post detailed update)
