How to Self-Host n8n AI Workflow Automation on a $4/Mo Hetzner VPS with Docker & SSL

Why Self-Host n8n Instead of Cloud SaaS?

While n8n Cloud and Zapier charge escalating fees for task volume, a $4.10/mo Hetzner Cloud VPS (CX22: 2 vCPU, 4GB RAM) allows you to execute unlimited workflows, webhooks, and AI agent steps for a fixed, ultra-low monthly cost.

5-Minute Deployment Guide

1. Provision a Hetzner Cloud Server

Select Ubuntu 24.04 LTS on the CX22 (2 vCPU, 4GB RAM) tier.
Add your SSH key and deploy in under 30 seconds.

2. Install Docker & Docker Compose

sudo apt update && sudo apt upgrade -y
sudo apt install -y docker.io docker-compose-plugin
sudo systemctl enable --now docker

3. Deploy n8n via Docker Compose

Create a docker-compose.yml file:

version: '3.8'
services:
  n8n:
    image: docker.n8n.io/n8nio/n8n
    restart: always
    ports:
      - "5678:5678"
    environment:
      - N8N_HOST=n8n.yourdomain.com
      - N8N_PORT=5678
      - N8N_PROTOCOL=https
      - WEBHOOK_URL=https://n8n.yourdomain.com/
    volumes:
      - n8n_data:/home/node/.n8n
