Disadvantages

✗Limited performance - ARM CPU is slower than x86 servers
✗8GB RAM maximum - Can be limiting for heavy workloads
✗SD card reliability - microSD cards can fail; NVMe recommended
✗Heat management - Pi 5 runs hot; needs good cooling
✗Slower Docker pulls - Initial setup takes longer on ARM
✗Some assembly required - Need to buy/assemble components

Things to Consider

Pi 5 vs Pi 4

Pi 5 (Recommended): 2-3x faster CPU, native PCIe for NVMe, better thermals.
Pi 4: Works but noticeably slower. Good if you already have one.
Pi 3 and older: Not recommended - too slow for Docker workloads.

Storage: SD Card vs NVMe

microSD ($15-30):Cheaper, simpler, but slower and less reliable long-term. SD cards can wear out from Docker's frequent writes.
NVMe via HAT ($40-80 total): 5-10x faster, much more reliable, recommended for serious use. Requires a Pi 5 M.2 HAT ($15-20) plus an NVMe drive ($25-50).

Cooling Requirements

Pi 5 runs hot under load. Minimum: Heatsink and passive case with good airflow.Recommended: Official active cooler or case with fan. Without proper cooling, the Pi will thermal throttle and slow down significantly.

4GB vs 8GB RAM

4GB ($60): Works for OpenClaw alone, but tight. Leave little headroom.
8GB ($80): Recommended. Comfortable for Docker + OpenClaw + room to grow. Only $20 more for double the RAM - worth it.

Power Supply

Pi 5 requires a proper 27W USB-C power supply. Underpowered supplies cause instability and "undervoltage" warnings. The official Pi 5 power supply is recommended - cheap alternatives often don't deliver enough current.

Expected Performance

OpenClaw will work well on Pi 5. Initial Docker image pull takes 5-10 minutes. After that, response times are good for personal use. Not suitable for high-traffic production deployments, but perfect for individual or small family use.

What You Need

Raspberry Pi 5 (8GB recommended)

4GB model works but 8GB is better for Docker

~$80

microSD card (32GB+) or NVMe SSD

NVMe via HAT recommended for speed and reliability

~$15-50

USB-C Power Supply (27W)

Official Raspberry Pi power supply recommended

~$12

Case with cooling

Active cooler or good passive case

~$10-20

Ethernet cable (recommended)

WiFi works but wired is more reliable

~$5

Total estimated cost: $95-170

Step 1: Install Raspberry Pi OS

Download Raspberry Pi Imager

Download and install the official Raspberry Pi Imager on your computer:

Download Raspberry Pi Imager →

Flash the OS

1. Insert your microSD card into your computer
2. Open Raspberry Pi Imager
3. Choose Raspberry Pi 5 as device
4. Choose Raspberry Pi OS (64-bit) - Lite version recommended
5. Click the gear icon to configure:

Configure these settings:

• Set hostname: openclaw
• Enable SSH (use password or key)
• Set username and password
• Configure WiFi (if not using ethernet)
• Set timezone

6. Click Write and wait for completion

Step 2: Boot and Connect

First boot

1. Insert the microSD card into your Raspberry Pi
2. Connect ethernet (if using)
3. Connect power - it will boot automatically
4. Wait 1-2 minutes for first boot to complete

Connect via SSH

ssh [email protected]

If openclaw.localdoesn't work, find the IP in your router's admin page.

Step 3: Install Docker

Run these commands on your Raspberry Pi:

# Update system
sudo apt update && sudo apt upgrade -y

# Install Docker
curl -fsSL https://get.docker.com | sh

# Add your user to docker group
sudo usermod -aG docker $USER

# Apply changes (or reboot)
newgrp docker

# Verify installation
docker run hello-world

Step 4: Deploy OpenClaw

Create directory and compose file

# Create directory
mkdir -p ~/openclaw && cd ~/openclaw

# Create docker-compose.yml
cat > docker-compose.yml << 'EOF'
version: '3.8'
services:
  openclaw:
    image: openclaw/openclaw:latest
    container_name: openclaw
    restart: unless-stopped
    ports:
      - "8080:8080"
    environment:
      - ANTHROPIC_API_KEY=${ANTHROPIC_API_KEY}
      - GATEWAY_TOKEN=${GATEWAY_TOKEN}
    volumes:
      - ./data:/app/data
EOF

Create .env file

cat > .env << EOF
OPENROUTER_API_KEY=sk-or-your-key-here
GATEWAY_TOKEN=$(openssl rand -hex 32)
EOF

Replace sk-or-your-key-here with your actual BYOK provider API key.

Start OpenClaw

docker compose up -d

First pull may be slow on SD card. NVMe is much faster.

Step 5: Enable Auto-Start

Create a systemd service so OpenClaw starts automatically on boot:

sudo cat > /etc/systemd/system/openclaw.service << EOF
[Unit]
Description=OpenClaw AI Assistant
After=docker.service
Requires=docker.service

[Service]
Type=oneshot
RemainAfterExit=yes
WorkingDirectory=/home/$USER/openclaw
ExecStart=/usr/bin/docker compose up -d
ExecStop=/usr/bin/docker compose down
User=$USER
Group=docker

[Install]
WantedBy=multi-user.target
EOF

# Enable the service
sudo systemctl daemon-reload
sudo systemctl enable openclaw

Accessing OpenClaw

Local Network

Access from any device on your network:

http://openclaw.local:8080

Or use the IP address: http://RASPBERRY_PI_IP:8080

Remote Access (Optional)

Access your Pi from anywhere with Cloudflare Tunnel. No port forwarding needed.

Performance Tips

Use NVMe storage

An NVMe SSD via a HAT is 5-10x faster than microSD. Highly recommended for Docker.

Enable zram

Raspberry Pi OS has zram enabled by default, which helps with the limited RAM.

Good cooling

Pi 5 runs hot. Use the official active cooler or a case with good airflow.

Wired ethernet

Gigabit ethernet is faster and more reliable than WiFi for an always-on server.
