Self-Hosting n8n on a $6/mo VPS with Docker: Production Guide (2026)

1. The Economics: $6/mo VPS vs. $500/mo Zapier

Modern businesses often find themselves penalized by SaaS pricing models simply for growing. Here is a real-world cost comparison at 50k and 200k operations per month:

2. Production Docker Compose Architecture

Never run self-hosted n8n on SQLite in production. A resilient setup uses PostgreSQL 16 with dedicated volume persistence and health checks:

version: '3.8'
services:
  postgres:
    image: postgres:16-alpine
    restart: always
    environment:
      POSTGRES_USER: ${POSTGRES_USER}
      POSTGRES_PASSWORD: ${POSTGRES_PASSWORD}
      POSTGRES_DB: n8n
    volumes:
      - postgres_data:/var/lib/postgresql/data
    healthcheck:
      test: ["CMD-SHELL", "pg_isready -h localhost -U ${POSTGRES_USER} -d n8n"]
      interval: 5s
      timeout: 5s
      retries: 10

  n8n:
    image: docker.n8n.io/n8nio/n8n:latest
    restart: always
    environment:
      - DB_TYPE=postgresdb
      - DB_POSTGRESDB_HOST=postgres
      - DB_POSTGRESDB_PORT=5432
      - DB_POSTGRESDB_DATABASE=n8n
      - DB_POSTGRESDB_USER=${POSTGRES_USER}
      - DB_POSTGRESDB_PASSWORD=${POSTGRES_PASSWORD}
      - N8N_HOST=n8n.yourcompany.com
      - WEBHOOK_URL=https://n8n.yourcompany.com/
      - EXECUTIONS_DATA_PRUNE=true
      - EXECUTIONS_DATA_MAX_AGE=168
    ports:
      - "127.0.0.1:5678:5678"
    depends_on:
      postgres:
        condition: service_healthy
    volumes:
      - n8n_data:/home/node/.n8n

volumes:
  postgres_data:
  n8n_data:

3. Automatic SSL & Reverse Proxy with Caddy

Instead of manually managing Let's Encrypt certificates with Certbot, use Caddy as a zero-config reverse proxy:

n8n.yourcompany.com {
    reverse_proxy 127.0.0.1:5678
}

Caddy automatically provisions, verifies, and renews your TLS certificates with zero manual intervention.

4. Hardening, Non-Root Users & Daily S3 Backups

A production server must be locked down against security threats:

• UFW Firewall: Allow only ports 22 (SSH with key-only auth), 80 (HTTP), and 443 (HTTPS). Block direct access to port 5678.
• Execution Pruning: Automatically prune execution logs older than 7 days (168 hours) to prevent disk space bloat.
• Automated S3 Backup: Run a daily pg_dump cron script that pushes encrypted database archives to Cloudflare R2 or Amazon S3.

Frequently Asked Questions

Why choose self-hosted n8n over n8n Cloud or Zapier?

Self-hosting grants unlimited workflow executions, zero per-task fees, access to native Python code execution, and 100% data privacy within your own server infrastructure.

What server specs are needed for a small business setup?

A standard $6 to $12/month VPS (e.g. Hetzner, DigitalOcean, Contabo) with 2 vCPUs, 4GB RAM, and 40GB SSD easily handles 50,000+ monthly workflow executions.

How are database backups handled in production?

We configure a daily automated cron job that dumps the PostgreSQL database, encrypts the snapshot, and syncs it offsite to Amazon S3 or Cloudflare R2.
