How to Set Up a VPS for Automation (Hetzner vs Contabo vs Railway)

What You’ll Need

• n8n Cloud or self-hosted n8n (you’ll be hosting this yourself)
• Hetzner VPS, Contabo VPS, or DigitalOcean
• Namecheap for a domain (optional but recommended)
• SSH client (built into macOS/Linux, PuTTY for Windows)
• Basic command-line familiarity

The Real Cost of Cloud-First Automation

I spent two years running automation workflows on managed platforms before I switched to self-hosted. Here’s what changed: my hosting costs dropped from $180/month to $8/month, and my workflow execution latency improved by 40%.

The catch? I had to learn infrastructure. But honestly, it’s worth it.

When you’re choosing between n8n Cloud and self-hosting, the decision isn’t just about price. It’s about control, scale, and whether you want to own the entire stack. If you’re automating business processes—pulling data from APIs, building integrations, or running bots 24/7—a VPS gives you freedom that managed platforms don’t.

The big question: which VPS provider should you actually use?

I’ve tested all three in production. Here’s what I learned.

Hetzner vs Contabo vs Railway: Head-to-Head

My take: If you’re serious about automation—especially if you’re considering 5 n8n workflows that replace $200/month in SaaS tools—you want Hetzner or Contabo. Railway is great for experimentation, but it’s not cost-optimized for 24/7 workloads.

Here’s why I pick Hetzner for most clients:

1. Consistent performance. Their NVMe storage is fast even on the cheapest tier.
2. Transparent pricing. No surprise overage charges.
3. European data centers. Lower latency if you’re in EU/Asia.
4. Easy scaling. If your bot explodes, you resize in the control panel.

Contabo wins if you need more storage and don’t want to pay per-GB. Railway wins if you want zero infrastructure knowledge required.

Setting Up Hetzner for n8n

I’m going to walk you through creating a production-ready Hetzner VPS instance running n8n.

Step 1: Create Your Hetzner Account and Deploy a Server

Sign up at Hetzner VPS. Go to Cloud → Servers → Create Server.

• Image: Ubuntu 22.04
• Server Type: CX11 (2 vCPU, 2 GB RAM, 25 GB NVMe)
• Location: Pick the closest to your users
• Add SSH Key: Generate one locally first

ssh-keygen -t ed25519 -C "your-email@example.com" -f ~/.ssh/hetzner_key

Copy the public key (~/.ssh/hetzner_key.pub) into Hetzner’s SSH key field. Click Create.

Step 2: SSH Into Your Server

ssh -i ~/.ssh/hetzner_key root@your_server_ip

Replace your_server_ip with the IP shown in Hetzner’s console.

Step 3: Update the System

apt update
apt upgrade -y
apt install -y curl wget git nano vim

Step 4: Install Docker and Docker Compose

curl -fsSL https://get.docker.com -o get-docker.sh
sh get-docker.sh
usermod -aG docker root
curl -L "https://github.com/docker/compose/releases/latest/download/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
chmod +x /usr/local/bin/docker-compose
docker-compose --version

Step 5: Set Up n8n with Docker Compose

Create a directory and a compose file:

mkdir -p /home/n8n && cd /home/n8n
nano docker-compose.yml

Paste this (adjust N8N_HOST to your domain):

version: '3.8'

services:
  n8n:
    image: n8nio/n8n:latest
    container_name: n8n
    ports:
      - "5678:5678"
    environment:
      - N8N_HOST=automation.yourdomain.com
      - N8N_PROTOCOL=https
      - NODE_ENV=production
      - WEBHOOK_URL=https://automation.yourdomain.com/
      - EXECUTIONS_TIMEOUT=3600
      - EXECUTIONS_TIMEOUT_MAX=7200
    volumes:
      - n8n_data:/home/node/.n8n
    restart: always

  postgres:
    image: postgres:15-alpine
    container_name: n8n_db
    environment:
      - POSTGRES_USER=n8n_user
      - POSTGRES_PASSWORD=your_secure_password_here
      - POSTGRES_DB=n8n
    volumes:
      - postgres_data:/var/lib/postgresql/data
    restart: always

volumes:
  n8n_data:
  postgres_data:

Replace your_secure_password_here with a strong password. Start the services:

docker-compose up -d

Step 6: Install and Configure Nginx (Reverse Proxy)

apt install -y nginx certbot python3-certbot-nginx
nano /etc/nginx/sites-available/n8n

Add this config (replace automation.yourdomain.com):

server {
    listen 80;
    server_name automation.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_buffering off;
    }
}

Enable the site and test:

ln -s /etc/nginx/sites-available/n8n /etc/nginx/sites-enabled/n8n
rm /etc/nginx/sites-enabled/default
nginx -t
systemctl restart nginx

Step 7: Secure with SSL

certbot certonly --nginx -d automation.yourdomain.com

Update your Nginx config to use the certificate:

nano /etc/nginx/sites-available/n8n

Replace the server block with this:

server {
    listen 80;
    server_name automation.yourdomain.com;
    return 301 https://$server_name$request_uri;
}

server {
    listen 443 ssl http2;
    server_name automation.yourdomain.com;

    ssl_certificate /etc/letsencrypt/live/automation.yourdomain.com/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/automation.yourdomain.com/privkey.pem;
    ssl_protocols TLSv1.2 TLSv1.3;
    ssl_ciphers HIGH:!aNULL:!MD5;

    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_buffering off;
    }
}

Restart Nginx:

nginx -t
systemctl restart nginx

Step 8: Access Your n8n Instance

Open your browser and go to https://automation.yourdomain.com. You’ll be prompted to create an admin account. Set a strong password. This is your entire automation system.

Setting Up Contabo for n8n

Contabo VPS is almost identical to Hetzner, but with more storage. The main difference: you get 200 GB SSD on the cheapest tier instead of 25 GB.

Step 1: Deploy a Server on Contabo

Sign up at Contabo VPS. Choose:

• VPS S ($3.99/month)
• Ubuntu 22.04 x64
• Add your SSH key during setup

Step 2: Connect and Initialize

ssh -i ~/.ssh/contabo_key root@your_contabo_ip
apt update && apt upgrade -y
apt install -y curl wget git nano docker.io

Step 3: Install Docker Compose

curl -L "https://github.com/docker/compose/releases/latest/download/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
chmod +x /usr/local/bin/docker-compose

Step 4: Deploy n8n (Same as Hetzner)

Use the exact same docker-compose.yml from the Hetzner section above. The setup is identical.

mkdir -p /home/n8n && cd /home/n8n
nano docker-compose.yml

Paste the Docker Compose config, then:

docker-compose up -d

Step 5: Nginx and SSL (Same as Hetzner)

Follow the exact Nginx and SSL steps from the Hetzner section above. The configuration doesn’t change between providers—it’s purely about the reverse proxy and certificate management, which work identically on Contabo.

The only thing you’ll change is the domain name and the SSH key path you use to connect. Everything else—the Nginx config, the SSL certificate setup with Certbot, the Docker port mapping—is identical.

After you’ve got SSL running, visit your domain and create your admin account.

Setting Up Railway for n8n

Railway is the fastest option if you just want n8n running without touching the command line. It’s not as cost-optimized as Hetzner or Contabo for 24/7 workloads, but it’s perfect for testing or if you want zero infrastructure overhead.

Deploy directly from Railway’s dashboard:

1. Sign up at Railway
2. Create a new project
3. Add a service → search “n8n”
4. Select the n8n template
5. Add a PostgreSQL database when prompted
6. Set your domain in the Railway settings
7. Deploy

Railway handles Nginx, SSL, and updates automatically. You’ll pay based on usage—typically $15–30/month for a modest automation workload. It’s the “I just want it to work” option.

Getting Started

You now have three solid paths forward:

1. n8n Cloud – managed, hands-off, most expensive
2. Hetzner VPS – cheapest for production, best performance-to-price ratio
3. Contabo VPS – more storage, same price as Hetzner
4. DigitalOcean – middle ground, slightly pricier, excellent docs

If you’re serious about automation and plan to run workflows continuously, pick Hetzner or Contabo, grab a domain from Namecheap, and follow the steps above.

If you’re experimenting, start with Railway or n8n Cloud. You can always migrate to self-hosted later—n8n exports cleanly.

The infrastructure is just the foundation. What matters is what you build on it. Your first automation workflow should solve a real problem in your business or client’s business. That’s where the ROI comes from.
