Running n8n Locally on a Windows Operating System

To run n8n locally on a Windows operating system, you have two primary methods: using Docker Desktop for a containerized, isolated environment, or using npm (Node Package Manager) for a more direct installation. The Docker method is highly recommended for its simplicity and consistency, as it packages all dependencies together. The npm approach requires installing Node.js first and then running n8n via a command-line terminal. Both methods allow you to access the n8n editor at http://localhost:5678 to build and test workflows directly on your machine, which is perfect for development, privacy, and cost-free experimentation.

Why Bother Running n8n Locally on Windows?

So, you’re ready to dive into the wonderful world of workflow automation with n8n. Fantastic! But your first big decision is where to run it. While n8n’s Cloud offering is powerful and convenient, setting up an n8n local Windows instance on your own machine has some serious perks, especially when you’re starting out or have specific needs.

Let’s be real, sometimes you just want to tinker without consequences. A local instance is the ultimate sandbox. You can build, break, and test the wildest workflow ideas without worrying about production data or cloud execution limits. It’s your personal automation playground!

Here’s a quick rundown of the advantages:

• Zero Cost to Start: You already have the computer. Running n8n locally leverages that hardware, meaning you can learn and build without paying for a server.
• Ultimate Privacy and Control: All your workflow data, credentials, and execution logs stay right there on your hard drive. This is a huge plus for sensitive information.
• Access to Local Files: This is a big one. You can use nodes like the Local File Trigger to watch a folder on your desktop and automatically process files—something you can’t do with the cloud version.
• Offline Access: No internet? No problem. You can still build and refine your workflows. (Though, you’ll obviously need a connection for nodes that access online services).

The Big Decision: npm vs. Docker

Before we get our hands dirty, we need to talk about the two main paths for a local Windows installation: npm and Docker. Think of it like this: the npm method is like building a PC from individual components. You install Node.js (the motherboard and CPU), then you install the n8n package (the graphics card). You have a lot of direct control, but you’re also responsible for making sure the parts work together.

The Docker method, on the other hand, is like buying a pre-built, high-end gaming console. It comes in a neat, sealed box (a “container”) with everything it needs to run perfectly, completely isolated from the rest of your system. You just plug it in and turn it on.

As an automation professional, I almost always point beginners toward Docker. It sidesteps a ton of potential “it works on my machine” issues. But to be fair, let’s compare them directly.

Method 1: The Docker Approach (The Easy Street)

I can’t stress this enough: if you’re unsure, choose this method. It saves headaches down the line.

Step 1: Install Docker Desktop

First, you need the Docker engine. Docker Desktop for Windows is a fantastic application that makes this a breeze. It uses the Windows Subsystem for Linux (WSL 2) under the hood to work its magic.

1. Head over to the official Docker website and download the installer.
2. Run the installer. It will likely prompt you to enable WSL 2 if it’s not already. Just follow the on-screen instructions; it handles most of the heavy lifting.
3. Restart your computer when it’s done. This is important!

Once restarted, Docker Desktop should be running (you’ll see a little whale icon in your system tray).

Step 2: The Magic Command

Now, open your terminal of choice. I prefer Windows Terminal with a PowerShell prompt, but the classic Command Prompt (CMD) works too.

Paste this single command and hit Enter:

docker run -it --rm --name n8n -p 5678:5678 -v ~/.n8n:/home/node/.n8n n8nio/n8n

Docker will now download the latest n8n image (if you don’t have it) and start it up. It looks intimidating, but it’s simple:

• docker run: The command to run a container.
• -it --rm: Tells Docker to run interactively and to remove the container when you stop it (keeps things tidy).
• --name n8n: Gives your container a friendly name so you can easily manage it later.
• -p 5678:5678: Maps your computer’s port 5678 to the container’s port 5678. This is how you access it.
• -v ~/.n8n:/home/node/.n8n: This is CRITICAL. It creates a persistent volume, linking a folder in your Windows user profile (~/.n8n) to the folder inside the container where n8n saves your workflows and credentials. Without this, your work will disappear when you stop the container!

Step 3: Access Your n8n Instance

That’s it! Open your web browser and navigate to http://localhost:5678. You’ll be greeted by the n8n setup screen. Success!

Method 2: The npm Approach (The Classic Way)

If you’re a Node.js developer or just don’t want to install Docker, this method is for you.

Step 1: Install Node.js

First, you need the Node.js runtime.

1. Go to the official Node.js website.
2. Download the LTS (Long-Term Support) version. It’s the most stable choice.
3. Run the installer, accepting the default options.

This also installs npm (Node Package Manager), which is like an app store for code packages like n8n.

Step 2: Install and Run n8n

Open a new PowerShell or CMD window. For the quickest and cleanest start, use this command:

npx n8n

npx is a handy tool that comes with npm. It fetches the latest n8n package, runs it, and doesn’t permanently install it on your system, which is great for avoiding clutter. The first time you run this, it will ask if you want to install the n8n package. Just type y and press Enter.

Your terminal will fill with some startup text, and that’s it!

Step 3: You’re In!

The npx n8n command should automatically open a new tab in your default browser pointed at http://localhost:5678. You’re ready to build!

The All-Important Question: “What Happens When I Restart?”

This is a fantastic and very practical question. A local server isn’t like a cloud service; it only runs when you tell it to.

For Docker Users:

Because we used the --rm flag, the container was deleted when you closed the terminal. To start it again with your saved data, you just need to run the same docker run... command from before. Docker will see the ~/.n8n folder and pick up right where you left off.

If you omitted the --rm flag, you can simply run docker start n8n.

For npm Users:

You need to open a terminal and run npx n8n again. A key thing to remember: that terminal window must remain open for n8n to keep running. If you close it, you shut down your n8n server.

A Real-World Power-Up: Local Invoice Processing

I recently had a project to automate invoice processing for a small business. They would save all their PDF invoices into a folder on their main office PC. Instead of a complex cloud setup, we used a local n8n instance on that Windows machine.

The workflow was simple but powerful:

1. Local File Trigger: I used the Read Binary Files node to watch the C:\Invoices-To-Process folder.
2. Text Extraction: When a new PDF was added, it was passed to a node that could extract raw text from the PDF.
3. Code Node Magic: A Code node with a few lines of JavaScript parsed the text to find the invoice number, date, and total amount.
4. Google Sheets: Finally, the Google Sheets node added this structured data as a new row in their accounting spreadsheet.

Running this on an n8n local Windows instance was perfect. It was incredibly fast to test, completely private, and cost them nothing extra. It’s a perfect example of leveraging local power for a real business problem.

Conclusion: Your Automation Journey Starts Here

Getting n8n up and running on your Windows machine is your first step toward becoming an automation wizard. It gives you a free, private, and powerful space to learn and experiment.

To recap: Docker is the recommended, more robust path for most users, while npm offers a quick and direct alternative, especially for those already in the JavaScript ecosystem. Whichever you choose, the important thing is to start. Fire up that local instance, connect a couple of nodes, and see what you can build. You’ll be surprised how quickly you get the hang of it!
