How to Install n8n: The Easiest Way to Automate Your Workflows

Automation is changing how we work by connecting apps and services to save time and reduce repetitive tasks. One of the best tools to help with this is n8n—an open-source workflow automation platform that lets you build complex automations with minimal coding. Whether you want to automatically move data between apps, send notifications, or build advanced business workflows, n8n offers a flexible and powerful solution.

This guide will walk you through how to install n8n using different methods—from quick local setups to production-ready deployments. You’ll learn which method suits your needs best, how to configure n8n securely, and some tips for running it smoothly.

What is n8n and Why Should You Use It?

Before we jump into installation, it’s important to understand what n8n is and why it’s become popular.

  • Open Source: Unlike many automation tools that charge monthly fees and restrict features, n8n is open source. This means you have full access to the source code, can customize it as you like, and run it on your own servers without ongoing licensing costs.
  • No-Code/Low-Code: n8n uses a visual editor where you can drag and drop “nodes” representing apps or actions. This makes automation accessible even if you aren’t a developer.
  • Highly Extensible: If you have coding skills, you can extend n8n’s functionality by writing custom JavaScript functions or nodes.
  • Flexible Hosting: You can self-host n8n for full control or use the official n8n Cloud service if you prefer a managed solution.
  • Wide Range of Integrations: With more than 200 supported apps—from Google Sheets to Slack, Twitter to AWS—n8n can automate almost anything.

Because of these advantages, n8n is used by freelancers, startups, and large companies alike to automate tasks, increase productivity, and reduce errors.

Prerequisites Before Installing n8n

System Requirements

n8n is fairly lightweight but you’ll want to meet these basic specs to run it comfortably:

  • Processor: Modern CPU (Intel or AMD)
  • RAM: At least 1GB; 2GB or more is recommended for production workloads
  • Disk Space: About 500MB minimum; more depending on data stored
  • Operating System: Linux, Windows, or macOS supported

If you’re installing on a cloud server (e.g., AWS, DigitalOcean), a small VPS with 2 CPUs and 2GB RAM is usually sufficient for many use cases.

Software Requirements

Depending on the installation method, your system might need:

  • Node.js (v16 or later): Required if installing with npm.
  • Docker & Docker Compose: Needed for containerized setups.
  • Git: Useful if cloning from the source repository.
  • Database (optional but recommended): SQLite is the default lightweight option, but PostgreSQL or MySQL is better for production.

General Recommendations

  • For security, create a dedicated user account on your server to run n8n.
  • Keep your system updated with the latest security patches.
  • Back up your workflows and database regularly.
  • Use environment variables to store sensitive data like passwords or API keys.

Overview of Installation Methods

You can install n8n in several ways:

  1. npm (Node Package Manager): Fast local setup, good for development and testing.
  2. Docker container: Portable, easy to run anywhere Docker is installed.
  3. Docker Compose: Recommended for production; handles multiple services and persistent storage.
  4. n8n Cloud: Fully managed hosted service.
  5. Desktop App: Native app for local testing and demos.

Each method has pros and cons depending on your needs, skill level, and where you want to run n8n.

Method 1: Install n8n Using npm (Node.js)

This is the fastest way to get n8n running locally if you want to try it out or develop workflows.

Step-by-Step Guide

  1. Install Node.js

Download and install Node.js (LTS version) from the official website: https://nodejs.org/.

Verify the installation by running in your terminal:

Bash
node -v
npm -v

Make sure Node.js version is 16 or higher.

  1. Install n8n Globally

Run:

Bash
npm install -g n8n

This installs n8n globally so you can run it from anywhere.

  1. Start n8n

Simply type:

Bash
n8n

The server will start, and you can open your browser to http://localhost:5678.

What Happens Behind the Scenes?

n8n runs a Node.js process that listens on port 5678 by default. The interface is a web app served locally. You can start creating workflows immediately.

Pros and Cons

  • Pros:
    • Quick and easy.
    • Great for beginners and developers.
    • No need to set up containers or databases initially.
  • Cons:
    • Not recommended for production; lacks process management.
    • If your terminal closes, n8n stops unless you use a process manager.
    • Data persistence is limited unless configured with an external database.

Tips for Stability

If you want to run n8n in the background, use a process manager like PM2:

Bash
npm install -g pm2
pm2 start n8n

PM2 keeps n8n running even if your terminal closes or your server restarts.

Method 2: Install Using Docker

Docker containers package all dependencies into a single image. This makes it easy to run n8n anywhere Docker is supported.

Step-by-Step Guide

  1. Install Docker

Follow official guides:

Verify installation:

Bash
docker --version
  1. Run n8n Docker Container

Run:

Bash
docker run -it --rm -p 5678:5678 n8nio/n8n

This will pull the official n8n image and start it.

  1. Access n8n

Open your browser to http://localhost:5678.

Adding Basic Authentication

By default, n8n runs without authentication, which is risky on public networks. To secure it, use environment variables:

Bash
docker run -it --rm -p 5678:5678 \
  -e N8N_BASIC_AUTH_ACTIVE=true \
  -e N8N_BASIC_AUTH_USER=myuser \
  -e N8N_BASIC_AUTH_PASSWORD=mypassword \
  n8nio/n8n

This requires you to enter credentials before accessing n8n.

Data Persistence with Volumes

Without volumes, data will be lost when the container stops. Mount a local folder to persist data:

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

Pros and Cons

  • Pros:
    • Containerization ensures a clean environment.
    • Easy deployment and upgrades.
    • Works on any OS with Docker.
  • Cons:
    • Needs basic Docker knowledge.
    • Must configure volumes for persistent data.
    • Environment variables need to be set explicitly.

Method 3: Install Using Docker Compose (Recommended for Production)

For production environments, running n8n with Docker Compose is ideal because it manages multiple services and persistent data.

What is Docker Compose?

Docker Compose is a tool for defining and running multi-container Docker applications using a YAML file.

Step-by-Step Guide

  1. Install Docker and Docker Compose

Confirm both are installed:

Bash
docker --version
docker-compose --version
  1. Create a docker-compose.yml File

Example:

YAML
version: "3.1"

services:
  n8n:
    image: n8nio/n8n
    restart: always
    ports:
      - 5678:5678
    environment:
      - N8N_BASIC_AUTH_ACTIVE=true
      - N8N_BASIC_AUTH_USER=myuser
      - N8N_BASIC_AUTH_PASSWORD=mypassword
      - DB_TYPE=postgresdb
      - DB_POSTGRESDB_HOST=postgres
      - DB_POSTGRESDB_PORT=5432
      - DB_POSTGRESDB_DATABASE=n8n
      - DB_POSTGRESDB_USER=n8nuser
      - DB_POSTGRESDB_PASSWORD=n8npassword
    volumes:
      - ./n8n-data:/home/node/.n8n

  postgres:
    image: postgres:13
    restart: always
    environment:
      - POSTGRES_USER=n8nuser
      - POSTGRES_PASSWORD=n8npassword
      - POSTGRES_DB=n8n
    volumes:
      - ./postgres-data:/var/lib/postgresql/data

This sets up n8n with a PostgreSQL database and persistent storage.

  1. Start Services

Run:

Bash
docker-compose up -d

This starts both the database and n8n.

  1. Verify

Access n8n at http://localhost:5678 and log in with your credentials.

Why Use PostgreSQL?

SQLite is fine for testing but lacks scalability and concurrent usage support. PostgreSQL is more robust, reliable, and preferred for production.

Setting Up Reverse Proxy & SSL

To secure your server with HTTPS, set up Nginx or Traefik as a reverse proxy in front of n8n.

Example Nginx snippet:

Nginx
server {
    listen 80;
    server_name yourdomain.com;

    location / {
        proxy_pass http://localhost:5678;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
    }
}

Use Let’s Encrypt to add free SSL certificates for secure traffic.

Pros and Cons

  • Pros:
    • Highly stable and scalable.
    • Data and configurations persist between restarts.
    • Easy to add more services like Redis, databases, etc.
  • Cons:
    • Initial setup requires more technical knowledge.
    • Managing multiple containers might be complex for beginners.

Method 4: Using n8n Cloud (Hosted Solution)
