How to Install and Run n8n Locally in 15 Minutes (Even If You're Not Technical)
Most businesses waste hundreds per month on cloud automation tools when they could run n8n for free on their own machines. This step-by-step guide shows exactly how to install n8n locally using npm - no coding experience required. Get full control of your workflows without monthly fees or vendor lock-in.
Why Run n8n Locally? (The Hidden Cost of Cloud Tools)
Most businesses start with cloud-based automation tools because they seem easier - but quickly hit three painful limitations. First, monthly fees add up fast (typically $20-$100 per user). Second, you're locked into the vendor's feature set and rate limits. Third, your sensitive data gets processed on someone else's servers.
Running n8n locally solves all three problems. You get:
Zero monthly costs: n8n is open-source and free to run on your own hardware. The only requirement is a computer you already own.
At 2:15 in the video, you'll see how simple the installation command is - just one line in your terminal. This accessibility is why n8n has become the go-to automation tool for technical and non-technical users alike.
What You Need Before Installing
You'll need just three things to get started:
- A Windows, Mac, or Linux computer (even an old laptop works)
- Node.js installed (we'll cover version requirements next)
- Administrator access to run installation commands
The entire installation takes about 15 minutes for most users. Unlike cloud services, there's no credit card required or account to create - just direct access to powerful automation tools.
Step-by-Step Installation Guide
Here's the complete process to get n8n running on your local machine:
Step 1: Open Terminal/PowerShell
On Windows, search for "PowerShell" and run it as Administrator. On Mac/Linux, open Terminal.
Step 2: Run the Installation Command
Copy and paste this exact command (from the official n8n docs):
npm install -g n8n
The -g flag installs n8n globally, making it available anywhere on your system.
Step 3: Wait for Installation
The process typically takes 2-5 minutes depending on your internet speed. You'll see progress indicators in your terminal.
In summary: 1) Open terminal as admin, 2) Run npm install -g n8n, 3) Wait for completion. That's all it takes to install.
Fixing Node.js Version Issues
If you see a message about incompatible Node.js versions (like at 4:30 in the video), here's how to fix it:
- Visit nodejs.org
- Download version 22.x (the current stable release)
- Run the installer with default settings
- Restart your terminal/PowerShell
n8n requires Node.js between versions 20.19 and 24.x. Version 22.x offers the best balance of stability and feature support.
Starting n8n For the First Time
Once installed, starting n8n is simple:
n8n start
This command launches the n8n web server on your local machine. You'll see output showing it's running on port 5678.
To access the interface:
- Open any web browser
- Navigate to
http://localhost:5678
You'll see the n8n setup screen where you can create your first user account and activate your license.
Activating Your Free License
At 10:45 in the video, you'll see the license activation process:
- Enter your email address
- Create a secure password
- Check your email for the license key
- Paste the key into the activation form
The license is completely free for individual and small business use. It simply helps the n8n team understand usage patterns.
Note: Even without internet access, n8n will continue working locally once activated. The license just enables automatic updates.
What to Build First
Now that n8n is running, here are three beginner-friendly automations to try:
- File backup: Automatically copy new files from one folder to another
- Email parsing: Extract data from incoming emails and save to a spreadsheet
- Webhook responder: Create API endpoints that trigger local scripts

Key Takeaways
Running n8n locally gives you enterprise-grade automation tools without the cloud subscription fees. The installation is simpler than most people expect - just npm and one command.
In summary: 1) Install Node.js, 2) Run npm install -g n8n, 3) Start with n8n start, 4) Access at localhost:5678. You now have a powerful automation platform running on your own hardware.
Frequently Asked Questions
Common questions about running n8n locally
Running n8n locally gives you complete control over your workflows without monthly fees. You avoid cloud service limitations, get better performance for local data processing, and maintain full privacy since your data never leaves your machine.
The tradeoff is you need to manage updates and security yourself. For businesses handling sensitive data or with budget constraints, local installation often makes more sense than cloud alternatives.
- No monthly fees - runs on hardware you already own
- Full control over workflow execution and scheduling
- Data stays within your local network
No coding experience is required. The installation uses npm (Node Package Manager), which handles all the technical setup automatically. You just need to copy and paste a few commands into PowerShell or Terminal.
The entire process takes about 15 minutes for most users. The n8n interface itself is completely visual - you build workflows by connecting nodes, not writing code.
- No programming knowledge needed
- Copy-paste terminal commands only
- Visual interface for building workflows
n8n requires Node.js version between 20.19 and 24.x. Version 22.x is recommended for best compatibility. If you have an older version, you'll need to update Node.js first - the installation will alert you if this is necessary.
Updating Node.js is simple - just download the installer from nodejs.org and run it. The process takes about 2 minutes and won't affect any existing projects on your machine.
- Requires Node.js 20.19-24.x
- Version 22.x recommended
- Easy to update if needed
Once installed, run 'n8n start' in your terminal. This launches a local web server you can access at http://localhost:5678 in any browser. The interface is completely web-based, so you'll manage your workflows through your browser after the initial setup.
For remote access, you can configure n8n to be accessible on your local network or via tunneling tools like ngrok. By default, it only accepts connections from your local machine for security.
- Run
n8n startcommand - Access at http://localhost:5678
- Web-based interface - no app to install
n8n requires a free license for local use, which you'll activate during initial setup. The license is free for individual and small business use. You'll receive it via email when you first access the web interface and complete the registration form.
The license helps the n8n team understand usage patterns while keeping the software free. It doesn't restrict features or require payment - it's simply a way to support continued development.
- Free license required
- No payment or credit card needed
- Sent via email during setup
Yes, but your computer needs to remain powered on and connected to the internet. For production use, consider a dedicated machine or server. Many users run n8n on a Raspberry Pi or old laptop repurposed as an automation server.
For critical workflows, you may want to set up monitoring to ensure n8n stays running. The software is stable, but power outages or system updates could interrupt service if not managed properly.
- Possible but requires always-on machine
- Consider dedicated hardware for reliability
- Raspberry Pi works well for low-cost 24/7 operation
Run 'npm update -g n8n' in your terminal. This updates to the latest version while preserving your existing workflows. It's recommended to update every few months to get new features and security improvements.
Before updating, you may want to back up your workflows (n8n makes this easy with export functionality). While updates are generally smooth, having a backup ensures you can revert if needed.
- Run
npm update -g n8n - Updates preserve existing workflows
- Recommended every 2-3 months
