How to Self-Host n8n: Build AI Workflows for $5/Month

Zapier gets expensive fast. 10,000 tasks = $193/month. 50,000 tasks = $769/month. n8n gives you unlimited workflows for the cost of a VPS.

This guide gets you self-hosted in 15 minutes.

What n8n Is

n8n (“n-eight-n”) is open-source workflow automation. Like Zapier or Make, but you control infrastructure and pricing.

400+ integrations
AI-native (LangChain support)
JavaScript/Python code when needed
Fair-code license (self-host free)
900+ workflow templates

v1.82.0 current as of April 2026.

Self-Host vs Cloud

Factor	n8n Cloud Pro	Self-Hosted
Price	$50/month	$5-15/month VPS
Executions	50,000/month	Unlimited
Data Control	n8n hosts	You own it
AI Models	Limited	Any (Ollama, local LLMs)

Requirements

VPS: 2 CPU cores, 4GB RAM minimum (8GB for AI)
Docker and Docker Compose
Domain name (optional, recommended)
Basic command line knowledge

Step 1: Server Setup

Ubuntu 22.04:

sudo apt update && sudo apt upgrade -y

Install Docker:

curl -fsSL https://get.docker.com -o get-docker.sh
sudo sh get-docker.sh
sudo usermod -aG docker $USER
newgrp docker

Install Docker Compose:

sudo apt install docker-compose-plugin -y

Step 2: Docker Compose

Create directory:

mkdir ~/n8n && cd ~/n8n

Create docker-compose.yml:

version: "3.8"

services:
  n8n:
    image: docker.n8n.io/n8nio/n8n:latest
    restart: always
    ports:
      - "5678:5678"
    environment:
      - N8N_BASIC_AUTH_ACTIVE=true
      - N8N_BASIC_AUTH_USER=your-username
      - N8N_BASIC_AUTH_PASSWORD=your-secure-password
      - N8N_HOST=n8n.yourdomain.com
      - N8N_PORT=5678
      - N8N_PROTOCOL=https
      - WEBHOOK_URL=https://n8n.yourdomain.com/
      - GENERIC_TIMEZONE=Europe/Rome
      - N8N_ENCRYPTION_KEY=your-encryption-key-here
    volumes:
      - n8n_data:/home/node/.n8n
      - /local-files:/files

volumes:
  n8n_data:

Generate encryption key (required):

openssl rand -base64 32

Important: Save this key. Lose it = lose all credentials.

Step 3: Start n8n

docker compose up -d

Check logs:

docker logs n8n-n8n-1 -f

Wait for “Editor is now accessible”.

Step 4: Access

Without domain:

http://YOUR_SERVER_IP:5678

Step 5: SSL with Nginx

Install:

sudo apt install nginx certbot python3-certbot-nginx -y

Create config:

sudo nano /etc/nginx/sites-available/n8n

Add:

server {
    listen 80;
    server_name n8n.yourdomain.com;

    location / {
        proxy_pass http://localhost:5678;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection 'upgrade';
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
        proxy_cache_bypass $http_upgrade;
    }
}

Enable SSL:

sudo ln -s /etc/nginx/sites-available/n8n /etc/nginx/sites-enabled/
sudo nginx -t
sudo systemctl reload nginx
sudo certbot --nginx -d n8n.yourdomain.com

Update docker-compose.yml with your domain, then:

docker compose down && docker compose up -d

First Workflow

Example: Starred Gmail → Notion database

Add Workflow
Gmail trigger: “Message Starred”
Notion node: Create database entry
Connect nodes
Execute Workflow to test
Activate to run automatically

AI Workflows

n8n integrates with LangChain:

OpenAI (GPT-4, GPT-3.5)
Ollama (self-hosted)
Vector databases (Pinecone, Supabase)

Example: New support ticket → Summarize with OpenAI → Post to Slack

Troubleshooting

Container won’t start:

docker logs n8n-n8n-1

Common issues:

Port 5678 in use: Change port mapping
Permission errors: Check volume permissions

Webhooks not working: Ensure WEBHOOK_URL matches your public URL.

Out of memory: Add swap:

sudo fallocate -l 4G /swapfile
sudo chmod 600 /swapfile
sudo mkswap /swapfile
sudo swapon /swapfile

Backups

Backup volume:

docker run --rm -v n8n_n8n_data:/data -v ~/backups:/backup alpine tar czf /backup/n8n-backup-$(date +%Y%m%d).tar.gz -C /data .

Security

Change default credentials
Use strong passwords
Enable 2FA in n8n settings
Restrict firewall (80, 443)

Keep updated:

docker compose pull && docker compose up -d

Regular backups

Scaling

For high volume, use PostgreSQL:

services:
  postgres:
    image: postgres:15
    environment:
      POSTGRES_USER: n8n
      POSTGRES_PASSWORD: secure-password
      POSTGRES_DB: n8n
    volumes:
      - postgres_data:/var/lib/postgresql/data

  n8n:
    environment:
      - DB_TYPE=postgresdb
      - DB_POSTGRESDB_HOST=postgres
      - DB_POSTGRESDB_USER=n8n
      - DB_POSTGRESDB_PASSWORD=secure-password

Summary

15 minutes setup. $5/month vs $193/month for 10,000 Zapier tasks. Unlimited executions. You own the data.

Trade-off: You manage infrastructure. With Docker, it’s mostly hands-off.

Start with basic setup. Explore AI workflows, custom nodes, advanced integrations as you grow.
