What is n8n? A Quick Explanation for Beginners

n8n (pronounced n-eight-n) is a flexible, source-available workflow automation platform that empowers you to connect different applications and services to automate repetitive tasks. It’s designed for a wide range of users, offering a visual, node-based editor for drag-and-drop simplicity, while also providing the power to write custom code (like JavaScript or Python) for complex logic. With options to self-host for complete data control or use a convenient cloud version, n8n stands out as a powerful tool for everything from simple social media posting to sophisticated AI-driven operations.

So, What Does n8n Actually Do?

Ever felt like you’re a human copy-paste machine, moving data from one app to another? That’s the exact problem n8n solves. Think of it like a set of digital LEGO blocks. Each application you use—like Slack, Google Sheets, HubSpot, or a custom database—is a different type of block, which n8n calls a node.

Your job is to connect these nodes on a visual canvas to create a workflow. A workflow is just a series of steps that run automatically. It usually starts with a Trigger Node, which kicks things off. For example, a trigger could be:

• Receiving a new email in Gmail.
• A customer making a purchase on Stripe.
• A new row being added to a Google Sheet.

Once the workflow is triggered, a sequence of Action Nodes takes over, passing data between each other to get the job done. It’s a beautifully simple concept with incredibly powerful implications.

The n8n Superpowers: What Makes It Different?

While there are other automation tools out there, n8n has a few unique characteristics that have made it a favorite, especially among technical teams and privacy-conscious users. Let’s be honest, not all automation tools are created equal.

Freedom to Build Your Way: Visual Editor Meets Real Code

This is the big one. Most automation platforms force you into one of two camps: either you’re a no-coder dragging boxes around, or you’re a developer writing scripts from scratch. n8n says, why not both?

You can build 90% of your workflow by visually connecting nodes, which is fast and intuitive. But what happens when you hit a wall? Maybe you need to transform data in a very specific way or connect to an obscure API that doesn’t have a dedicated node. Instead of giving up, you can just drop in a Code Node and write a snippet of JavaScript or Python. This flexibility is a game-changer because it means there are virtually no limits to what you can build.

You Control Your Data: Self-Hosting vs. Cloud

In an age of data breaches and privacy concerns, knowing where your data lives is critical. n8n gives you a choice:

1. n8n Cloud: The easy-peasy, get-started-in-seconds option. They handle the servers, security, and updates for you.
2. Self-Hosting: You can run n8n on your own infrastructure—be it a Raspberry Pi in your closet, a server in your office, or a private cloud instance (like AWS or DigitalOcean). This means your sensitive customer data and credentials never have to leave your control.

This self-hosting capability is a massive advantage for companies in regulated industries like healthcare or finance, or for anyone who simply prefers to own their stack.

Fair-Code and Source-Available: What’s the Big Deal?

n8n operates on a “fair-code” license. This is a bit different from pure open-source, but the spirit is similar. It means the source code is publicly available for you to see, modify, and use. You can inspect it for security, fix bugs yourself, or even build your own custom nodes.

This transparency builds a huge amount of trust. You’re not using a mysterious black box; you can see exactly how it works. It also fosters a vibrant community of users who contribute new integrations and templates, making the platform better for everyone.

A Real-World Example: Automating New Customer Onboarding

Let’s make this tangible. Imagine you run a small software company. Every time a new customer signs up via Stripe, your team manually performs a checklist of tasks that takes about 15 minutes.

• The Problem: It’s slow, prone to human error, and doesn’t scale as your business grows.

• The n8n Workflow:

  1. Trigger: A Stripe Node listens for a charge.succeeded event.
  2. Action 1: The customer’s email and name are passed to a HubSpot Node, which creates or updates a contact record in your CRM.
  3. Action 2: An HTTP Request Node sends the customer’s details to your application’s internal API to provision their new account.
  4. Logic: An IF Node checks the response from the API. Was the account created successfully?
  5. Success Path: If yes, a Gmail Node sends a personalized welcome email with login details, and a Slack Node posts a celebratory “🎉 New customer!” message to the team.
  6. Fail Path: If no, the Slack Node sends an alert to your technical team with the error details so they can investigate immediately.

• The Outcome: The entire onboarding process is now instant, error-free, and fully automated. Your team saves hours every week, and customers get a better experience. That’s the power of what n8n can do.

Getting Started with n8n

Ready to dive in? The best way to learn is by doing.

1. Try the Cloud: Sign up for a free trial on the n8n Cloud to get a feel for the interface without any setup.
2. Run it Locally (in 60 seconds): If you have Node.js installed on your computer, you can test n8n instantly by opening your terminal and running this command: npx n8n. This will start a temporary n8n instance right on your machine.

From there, explore the hundreds of workflow templates and connect your favorite apps. Don’t be afraid to break things! That’s how you learn.

Ultimately, n8n is more than just an automation tool; it’s a creative platform for solving problems you didn’t even know you could automate. (And in case you were still wondering, the name comes from an abbreviation of “nodemation”—a nod to its node-based design and focus on automation). Now go build something amazing!
