| Host OpenClaw on a Raspberry Pi for always-on self-hosting |

Raspberry Pi
Run a persistent, always-on OpenClaw Gateway on a Raspberry Pi. Since the Pi is just the gateway (models run in the cloud via API), even a modest Pi handles the workload well.
Prerequisites
- Raspberry Pi 4 or 5 with 2 GB+ RAM (4 GB recommended)
- MicroSD card (16 GB+) or USB SSD (better performance)
- Official Pi power supply
- Network connection (Ethernet or WiFi)
- 64-bit Raspberry Pi OS (required -- do not use 32-bit)
- About 30 minutes
Setup
Use **Raspberry Pi OS Lite (64-bit)** -- no desktop needed for a headless server.1. Download [Raspberry Pi Imager](https://www.raspberrypi.com/software/).
2. Choose OS: **Raspberry Pi OS Lite (64-bit)**.
3. In the settings dialog, pre-configure:
- Hostname: `gateway-host`
- Enable SSH
- Set username and password
- Configure WiFi (if not using Ethernet)
4. Flash to your SD card or USB drive, insert it, and boot the Pi.
```bash
ssh user@gateway-host
```
```bash
sudo apt update && sudo apt upgrade -y
sudo apt install -y git curl build-essential
# Set timezone (important for cron and reminders)
sudo timedatectl set-timezone America/Chicago
```
```bash
curl -fsSL https://deb.nodesource.com/setup_24.x | sudo -E bash -
sudo apt install -y nodejs
node --version
```
```bash
sudo fallocate -l 2G /swapfile
sudo chmod 600 /swapfile
sudo mkswap /swapfile
sudo swapon /swapfile
echo '/swapfile none swap sw 0 0' | sudo tee -a /etc/fstab
# Reduce swappiness for low-RAM devices
echo 'vm.swappiness=10' | sudo tee -a /etc/sysctl.conf
sudo sysctl -p
```
```bash
curl -fsSL https://openclaw.ai/install.sh | bash
```
```bash
openclaw onboard --install-daemon
```
Follow the wizard. API keys are recommended over OAuth for headless devices. Telegram is the easiest channel to start with.
```bash
openclaw status
sudo systemctl status openclaw
journalctl -u openclaw -f
```
On your computer, get a dashboard URL from the Pi:
```bash
ssh user@gateway-host 'openclaw dashboard --no-open'
```
Then create an SSH tunnel in another terminal:
```bash
ssh -N -L 18789:127.0.0.1:18789 user@gateway-host
```
Open the printed URL in your local browser. For always-on remote access, see [Tailscale integration](/gateway/tailscale).
Performance tips
Use a USB SSD -- SD cards are slow and wear out. A USB SSD dramatically improves performance. See the Pi USB boot guide.
Enable module compile cache -- Speeds up repeated CLI invocations on lower-power Pi hosts:
grep -q 'NODE_COMPILE_CACHE=/var/tmp/openclaw-compile-cache' ~/.bashrc || cat >> ~/.bashrc <<'EOF' # pragma: allowlist secret
export NODE_COMPILE_CACHE=/var/tmp/openclaw-compile-cache
mkdir -p /var/tmp/openclaw-compile-cache
export OPENCLAW_NO_RESPAWN=1
EOF
source ~/.bashrc
Reduce memory usage -- For headless setups, free GPU memory and disable unused services:
echo 'gpu_mem=16' | sudo tee -a /boot/config.txt
sudo systemctl disable bluetooth
Troubleshooting
Out of memory -- Verify swap is active with free -h. Disable unused services (sudo systemctl disable cups bluetooth avahi-daemon). Use API-based models only.
Slow performance -- Use a USB SSD instead of an SD card. Check for CPU throttling with vcgencmd get_throttled (should return 0x0).
Service will not start -- Check logs with journalctl -u openclaw --no-pager -n 100 and run openclaw doctor --non-interactive.
ARM binary issues -- If a skill fails with "exec format error", check whether the binary has an ARM64 build. Verify architecture with uname -m (should show aarch64).
WiFi drops -- Disable WiFi power management: sudo iwconfig wlan0 power off.
