What is n8n? The Automation Tool You Wish to Know Before

How many hours per week do you lose copying data between apps, answering the same emails, or chasing updates across tools?

What if you could automate all that - for free, with full data privacy, and even add smart AI - without needing to be a full-time developer?

That's exactly what n8n delivers.

n8n (pronounced "n-eight-n" or "nodemation") is a free, open-source workflow automation tool that connects your favorite apps and services, allowing them to work together seamlessly without manual intervention.

Think of n8n as your digital assistant that never sleeps. It watches for specific events – like receiving an email, getting a form submission, or a new row appearing in a spreadsheet – and automatically performs a series of actions in response

The n8n Philosophy: Fair-Code Distribution

Unlike traditional SaaS automation tools that lock you into monthly subscriptions based on usage, n8n operates on a "fair-code" license. This means:

• You can use it completely free for personal and commercial projects

• Self-host it on your own servers for full data control

• No limits on the number of workflows or executions

• Access to all features without paywalls

Why n8n is Different from Other Automation Tools

1. 100% Free and Open Source

While platforms like Zapier and Make charge based on the number of tasks you run monthly (often starting at $20-30/month), n8n is completely free. You can process unlimited workflows without worrying about hitting task limits or surprise bills.

2. Full Data Ownership and Privacy

With n8n's self-hosting option, your sensitive data never leaves your infrastructure. This is crucial for:

• Businesses handling confidential client information

• Healthcare and finance industries with strict compliance requirements

• Anyone concerned about data privacy

3. No Code Required (But Code-Friendly)

n8n's visual workflow builder means you can create sophisticated automations by dragging and dropping nodes. But if you know JavaScript, Python, or other programming languages, you can write custom code directly in your workflows for unlimited possibilities.

4. 400+ Native Integrations

n8n connects with over 400 popular services out of the box, including:

• Communication: Slack, Discord, Telegram, Microsoft Teams

• Productivity: Gmail, Google Drive, Notion, Airtable, Trello

• Marketing: HubSpot, Mailchimp, WordPress, social media platforms

• Development: GitHub, GitLab, Jira, Jenkins

• Databases: PostgreSQL, MongoDB, MySQL, Redis

Can't find the integration you need? n8n's HTTP Request node lets you connect to any API, and the active community regularly contributes new integrations.

How Does n8n Work? A Beginner-Friendly Explanation

1. The Building Blocks: Nodes and Workflows

n8n operates using two core concepts:

a. Nodes – Individual building blocks that represent either:

• Trigger nodes: Start your workflow when something happens (new email, webhook received, scheduled time)

• Action nodes: Perform specific tasks (send message, create database entry, process data)

• Logic nodes: Add decision-making and data manipulation (if/else conditions, loops, filters)

b. Workflows – Connected sequences of nodes that define your automation logic

2. A Simple Example: Email to Task Automation

Let's say you want every email with "URGENT" in the subject to automatically create a high-priority task in your project management tool. Here's how it works in n8n:

Step 1: Gmail Trigger node watches for new emails
Step 2: Filter node checks if subject contains "URGENT"
Step 3: If yes → Create high-priority task in Asana
Step 4: Send Slack notification to your team

This entire workflow runs automatically in the background, saving you from constantly monitoring your inbox and manually creating tasks.

3. Visual Workflow Editor

n8n's canvas-based interface makes building workflows intuitive. You simply:

1. Drag nodes from the sidebar onto your canvas

2. Connect them by drawing lines between connection points

3. Configure each node with your specific settings

4. Test your workflow with real data

5. Activate it to run automatically

No complex coding required – though the option is always there when you need it.
