How to Install n8n Locally in 2025?

I’m fumbling in my makeshift home office, surrounded by coffee mugs and tangled cables, trying to streamline my freelance tasks. Emails, data scraping, social posts—it’s chaos. A colleague mentions n8n, a free automation tool that connects apps like magic.

But the cloud version feels limited, so I decide to install it locally for full control.

My first attempt? A disaster. Wrong commands, permission errors, and a frozen screen. But after tweaking and testing, my local n8n instance hums along, automating my workflow like a pro.

I spent days experimenting with npm and Docker setups on my Mac, then verified on Windows via a virtual machine.

This guide shares my triumphs and fails, plus online tips, to make your n8n local installation smooth. If you’re tired of manual tasks, let’s get n8n running on your machine!

What Is n8n? The Workflow Automation Tool You Need

n8n is an open-source workflow automation platform that lets you connect apps, APIs, and services without coding. Think Zapier or IFTTT, but free and self-hosted.

It uses a node-based interface to create automations—like syncing Google Sheets with Slack or scraping web data. In 2025, it’s a favorite for developers, marketers, and hobbyists wanting privacy and customization.

I used n8n to auto-post my blog updates to Twitter, saving hours weekly. Online buzz calls it “the Swiss Army knife of automation,” with users praising its 300+ nodes for tasks from email to AI integrations.

Why Install n8n Locally? The Benefits Over Cloud

Running n8n in the cloud is easy, but local installation gives you full control. No data limits, better privacy (your info stays on your machine), and offline access for testing. It’s ideal for sensitive workflows or learning without costs. Plus, it’s free forever—no subscription traps.

In my setup, local n8n let me tweak nodes without the internet, perfect for travel. Users on forums note it’s faster for heavy tasks, avoiding cloud lag.

Requirements for Installing n8n Locally in 2025

Before diving in, check these basics:

• Hardware: At least 2 GB RAM, 10 GB storage (more for complex workflows).
• OS: Windows, macOS, or Linux (works on all).
• Software: Node.js (v18+), npm (v8+), or Docker (v20+).
• Internet: Needed for initial install and node downloads; offline after.
• Firewall: Open port 5678 for web access (local only).

I ran it on my Mac with 16 GB RAM—no issues. For Windows, ensure WSL if using Linux commands.

How to Install n8n Locally Using npm: Step-by-Step Guide

npm is the simplest for beginners. Here’s how I did it, with OS tips.

Step 1: Install Node.js and npm

• Download from nodejs.org (LTS version).

• Windows/Mac: Run installer.

• Linux: Past this code

sudo apt install nodejs npm

• Verify:

node -v

And

 npm -v

I skipped this on my Mac (already installed), but on Windows, it took 5 minutes.

Step 2: Install n8n Globally

Open terminal/Command Prompt.

• Run:

npm install n8n -g

This downloads n8n and dependencies.

My install took 2 minutes; if errors, check npm permissions.

Step 3: Start n8n

• Run:

n8n start

• Access at http://localhost:5678.
• Set up credentials on first login.

I saw the dashboard instantly—nodes ready for automation.

OS-Specific Tips

• Windows: Use PowerShell as admin for global install.
• Mac: May need sudo for permissions.
• Linux: Ensure npm path is in $PATH; add to .bashrc if needed.

npm Installation Commands by OS

OS	Install Node.js	Install n8n	Start n8n
Windows	Download from nodejs.org	npm install n8n -g	n8n start
Mac	brew install node (via Homebrew)	sudo npm install n8n -g	n8n start
Linux	sudo apt install nodejs npm	sudo npm install n8n -g	n8n start

How to Install n8n Locally Using Docker: Step-by-Step Guide

Docker is great for isolated setups. I preferred it for easy updates.

Step 1: Install Docker

• Download Docker Desktop from docker.com.
• Windows/Mac: Run installer.
• Linux: Follow OS-specific guides (e.g., sudo apt install docker-ce).
• Verify:

docker --version.

My Mac install was smooth; Windows needed Hyper-V enabled.

Step 2: Create a Data Volume

Run:

docker volume create n8n_data

This persists your workflows.

Step 3: Run n8n Container

Basic command:

docker run -it --rm --name n8n -p 5678:5678 -v n8n_data:/home/node/.n8n docker.n8n.io/n8nio/n8n

Add timezone:

-e TZ="America/New_York"

For PostgreSQL: More complex—set DB env vars.

I accessed http://localhost:5678 instantly.

OS-Specific Tips

• Windows: Use Docker Desktop; enable WSL2.
• Mac: Docker Desktop handles it.
• Linux: Ensure Docker group permissions.

Docker Command Options

• -p 5678:5678: Map ports.
• -v n8n_data:/home/node/.n8n: Persist data.
• –name n8n: Name container.
• -e TZ=”<timezone>”: Set time.

Troubleshooting Common n8n Local Installation Issues

I hit a few bumps—here’s how I fixed them.

• Permission Errors: Use sudo (Mac/Linux) or admin mode (Windows).
• Port 5678 Busy: Run lsof -i :5678 to kill processes.
• npm Install Fails: Update npm: npm install -g npm.
• Docker Pull Errors: Check internet; clear cache: docker system prune.
• Slow Performance: Use larger RAM for container or npm.
• Login Issues: Reset credentials via command line.

Online tips helped—common for 2025 updates.

How to Update n8n Locally: Keep It Fresh

For npm:

npm update n8n -g

For Docker: Pull new image:

docker pull docker.n8n.io/n8nio/n8n

then restart container.

I updated seamlessly—no data loss with volumes.

Best Practices for Running n8n Locally

• Secure with HTTPS: Use Caddy or NGINX reverse proxy.
• Backup Workflows: Export JSON regularly.
• Monitor Resources: Use top/htop to check CPU.
• Integrate Databases: Switch to PostgreSQL for production.
• Scale with Docker Compose: For multi-container setups.

My local n8n now automates everything from backups to alerts.
