OpenClaw on a $5 VPS: Always-On AI Agent with Zero Hardware

No Hardware, No Problem

You don’t need a Raspberry Pi. You don’t need a Mac Mini. You don’t need any hardware at all. A $5/month VPS runs OpenClaw perfectly — and Oracle Cloud’s free tier means you can do it for $0.

Why a VPS Works

OpenClaw’s gateway requirements are minimal:

• CPU: 1 vCPU (ARM or x86)
• RAM: 1-2GB
• Storage: 5GB for the gateway + workspace
• Network: Stable internet (the gateway needs to maintain WebSocket connections to Discord, WhatsApp, etc.)

That’s well within the specs of the cheapest VPS tiers from any provider.

Option 1: Oracle Cloud Free Tier ($0/month)

Oracle offers an always-free ARM instance with specs that dwarf what OpenClaw needs:

# Oracle Cloud free tier: ARM Ampere A1
# 4 OCPUs, 24GB RAM, 200GB storage
# Yes, really. For free. Forever.

# Create an instance via Oracle Cloud Console:
# Shape: VM.Standard.A1.Flex
# Image: Ubuntu 24.04 (aarch64)
# Storage: 50GB boot volume (plenty)

After provisioning:

# SSH in
ssh ubuntu@<your-instance-ip>

# Install Docker
curl -fsSL https://get.docker.com | sh
sudo usermod -aG docker $USER
# Log out and back in

# Deploy OpenClaw
mkdir -p ~/openclaw && cd ~/openclaw

cat > docker-compose.yml << 'EOF'
version: '3.8'
services:
  openclaw:
    image: ghcr.io/openclaw/openclaw:latest
    container_name: openclaw
    restart: unless-stopped
    ports:
      - "3000:3000"
    volumes:
      - ./config:/home/node/.openclaw
      - ./workspace:/home/node/.openclaw/workspace
    environment:
      - TZ=Europe/Amsterdam
EOF

docker compose up -d

# Run onboarding
docker exec -it openclaw openclaw onboard

Option 2: Hetzner Cloud (€3.79/month)

Hetzner’s CX22 is the best value in cloud:

# CX22: 2 vCPU, 4GB RAM, 40GB SSD, 20TB traffic
# €3.79/month (~$4.10)

# Create via Hetzner CLI or console
hcloud server create \
  --name openclaw \
  --type cx22 \
  --image ubuntu-24.04 \
  --ssh-key my-key

# Same Docker setup as above

Option 3: DigitalOcean ($6/month)

# Basic droplet: 1 vCPU, 1GB RAM, 25GB SSD
doctl compute droplet create openclaw \
  --size s-1vcpu-1gb \
  --image ubuntu-24-04-x64 \
  --region ams3 \
  --ssh-keys <key-fingerprint>

Securing Your VPS

A public-facing OpenClaw instance needs basic security:

# 1. Firewall — only allow SSH and OpenClaw control UI
sudo ufw default deny incoming
sudo ufw allow 22/tcp
sudo ufw allow 3000/tcp  # Control UI (consider removing if not needed)
sudo ufw enable

# 2. SSH hardening
sudo sed -i 's/#PasswordAuthentication yes/PasswordAuthentication no/' /etc/ssh/sshd_config
sudo systemctl restart sshd

# 3. Auto-updates
sudo apt install -y unattended-upgrades
sudo dpkg-reconfigure -plow unattended-upgrades

# 4. Fail2ban
sudo apt install -y fail2ban
sudo systemctl enable fail2ban

Configuring GPT-5-mini

# Inside the container
docker exec -it openclaw openclaw configure --section copilot

# Set the model
docker exec -it openclaw sh -c 'cat >> /home/node/.openclaw/openclaw.yaml << EOF
models:
  default: github-copilot/gpt-5-mini
EOF'

# Restart to apply
docker compose restart

Monitoring and Maintenance

# Check status
docker exec openclaw openclaw status

# View logs
docker logs -f openclaw --tail 100

# Auto-restart on crash (already handled by restart: unless-stopped)

# Update to latest version
docker compose pull
docker compose up -d

# Backup config and workspace
tar czf openclaw-backup-$(date +%F).tar.gz config/ workspace/

VPS vs Pi: When to Choose What

Choose VPS when:

• You don’t want hardware at home
• You need a static public IP
• You want easy snapshots and backups
• You’re already managing cloud infrastructure

Choose Pi when:

• You want full physical control
• You pair OpenClaw with home devices (cameras, speakers)
• You prefer one-time cost over recurring
• You’re in a location with unreliable internet to cloud providers

Cost Summary

Oracle Cloud free tier:     $0/month  + $10 Copilot Pro = $10/month
Hetzner CX22:              $4/month  + $10 Copilot Pro = $14/month
DigitalOcean Basic:         $6/month  + $10 Copilot Pro = $16/month
Raspberry Pi 5 (amortized): $3/month  + $10 Copilot Pro = $13/month

All of these are under $20/month for a state-of-the-art AI agent that’s always on, always reachable, and handles everything from code generation to home automation.

The Oracle Cloud free tier is genuinely hard to beat — 4 CPUs and 24GB RAM for free is absurd overkill for OpenClaw, but it means you’ll never worry about resources.
