Clawdbot on Raspberry Pi (budget self-hosted setup)

Setting up Clawdbot on a Raspberry Pi

Running Clawdbot on ARM devices

Building a cheap always-on personal AI

Clawdbot on Raspberry Pi

Goal

Run a persistent, always-on Clawdbot Gateway on a Raspberry Pi for ~$35-80 one-time cost (no monthly fees).

Perfect for:

24/7 personal AI assistant
Home automation hub
Low-power, always-available Telegram/WhatsApp bot

Hardware Requirements

Pi Model	RAM	Works?	Notes
Pi 5	4GB/8GB	✅ Best	Fastest, recommended
Pi 4	4GB	✅ Good	Sweet spot for most users
Pi 4	2GB	✅ OK	Works, add swap
Pi 4	1GB	⚠️ Tight	Possible with swap, minimal config
Pi 3B+	1GB	⚠️ Slow	Works but sluggish
Pi Zero 2 W	512MB	❌	Not recommended

Minimum specs: 1GB RAM, 1 core, 500MB disk
Recommended: 2GB+ RAM, 64-bit OS, 16GB+ SD card (or USB SSD)

What You'll Need

Raspberry Pi 4 or 5 (2GB+ recommended)
MicroSD card (16GB+) or USB SSD (better performance)
Power supply (official Pi PSU recommended)
Network connection (Ethernet or WiFi)
~30 minutes

1) Flash the OS

Use Raspberry Pi OS Lite (64-bit) — no desktop needed for a headless server.

Download Raspberry Pi Imager
Choose OS: Raspberry Pi OS Lite (64-bit)
Click the gear icon (⚙️) to pre-configure:
- Set hostname: gateway-host
- Enable SSH
- Set username/password
- Configure WiFi (if not using Ethernet)
Flash to your SD card / USB drive
Insert and boot the Pi

2) Connect via SSH

ssh user@gateway-host
# or use the IP address
ssh user@192.168.x.x

3) System Setup

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

# Install essential packages
sudo apt install -y git curl build-essential

# Set timezone (important for cron/reminders)
sudo timedatectl set-timezone America/Chicago  # Change to your timezone

4) Install Node.js 22 (ARM64)

# Install Node.js via NodeSource
curl -fsSL https://deb.nodesource.com/setup_22.x | sudo -E bash -
sudo apt install -y nodejs

# Verify
node --version  # Should show v22.x.x
npm --version

5) Add Swap (Important for 2GB or less)

Swap prevents out-of-memory crashes:

# Create 2GB swap file
sudo fallocate -l 2G /swapfile
sudo chmod 600 /swapfile
sudo mkswap /swapfile
sudo swapon /swapfile

# Make permanent
echo '/swapfile none swap sw 0 0' | sudo tee -a /etc/fstab

# Optimize for low RAM (reduce swappiness)
echo 'vm.swappiness=10' | sudo tee -a /etc/sysctl.conf
sudo sysctl -p

6) Install Clawdbot

Option A: Standard Install (Recommended)

curl -fsSL https://clawd.bot/install.sh | bash

Option B: Hackable Install (For tinkering)

git clone https://github.com/clawdbot/clawdbot.git
cd clawdbot
npm install
npm run build
npm link

The hackable install gives you direct access to logs and code — useful for debugging ARM-specific issues.

7) Run Onboarding

clawdbot onboard --install-daemon

Follow the wizard:

Gateway mode: Local
Auth: API keys recommended (OAuth can be finicky on headless Pi)
Channels: Telegram is easiest to start with
Daemon: Yes (systemd)

8) Verify Installation

# Check status
clawdbot status

# Check service
sudo systemctl status clawdbot

# View logs
journalctl -u clawdbot -f

9) Access the Dashboard

Since the Pi is headless, use an SSH tunnel:

# From your laptop/desktop
ssh -L 18789:localhost:18789 user@gateway-host

# Then open in browser
open http://localhost:18789

Or use Tailscale for always-on access:

# On the Pi
curl -fsSL https://tailscale.com/install.sh | sh
sudo tailscale up

# Update config
clawdbot config set gateway.bind tailnet
sudo systemctl restart clawdbot

Performance Optimizations

Use a USB SSD (Huge Improvement)

SD cards are slow and wear out. A USB SSD dramatically improves performance:

# Check if booting from USB
lsblk

See Pi USB boot guide for setup.

Reduce Memory Usage

# Disable GPU memory allocation (headless)
echo 'gpu_mem=16' | sudo tee -a /boot/config.txt

# Disable Bluetooth if not needed
sudo systemctl disable bluetooth

Monitor Resources

# Check memory
free -h

# Check CPU temperature
vcgencmd measure_temp

# Live monitoring
htop

ARM-Specific Notes

Binary Compatibility

Most Clawdbot features work on ARM64, but some external binaries may need ARM builds:

Tool	ARM64 Status	Notes
Node.js	✅	Works great
WhatsApp (Baileys)	✅	Pure JS, no issues
Telegram	✅	Pure JS, no issues
gog (Gmail CLI)	⚠️	Check for ARM release
Chromium (browser)	✅	`sudo apt install chromium-browser`

If a skill fails, check if its binary has an ARM build. Many Go/Rust tools do; some don't.

32-bit vs 64-bit

Always use 64-bit OS. Node.js and many modern tools require it. Check with:

uname -m
# Should show: aarch64 (64-bit) not armv7l (32-bit)

Recommended Model Setup

Since the Pi is just the Gateway (models run in the cloud), use API-based models:

{
  "agents": {
    "defaults": {
      "model": {
        "primary": "anthropic/claude-sonnet-4-20250514",
        "fallbacks": ["openai/gpt-4o-mini"]
      }
    }
  }
}

Don't try to run local LLMs on a Pi — even small models are too slow. Let Claude/GPT do the heavy lifting.

Auto-Start on Boot

The onboarding wizard sets this up, but to verify:

# Check service is enabled
sudo systemctl is-enabled clawdbot

# Enable if not
sudo systemctl enable clawdbot

# Start on boot
sudo systemctl start clawdbot

Troubleshooting

Out of Memory (OOM)

# Check memory
free -h

# Add more swap (see Step 5)
# Or reduce services running on the Pi

Slow Performance

Use USB SSD instead of SD card
Disable unused services: sudo systemctl disable cups bluetooth avahi-daemon
Check CPU throttling: vcgencmd get_throttled (should return 0x0)

Service Won't Start

# Check logs
journalctl -u clawdbot --no-pager -n 100

# Common fix: rebuild
cd ~/clawdbot  # if using hackable install
npm run build
sudo systemctl restart clawdbot

ARM Binary Issues

If a skill fails with "exec format error":

Check if the binary has an ARM64 build
Try building from source
Or use a Docker container with ARM support

WiFi Drops

For headless Pis on WiFi:

# Disable WiFi power management
sudo iwconfig wlan0 power off

# Make permanent
echo 'wireless-power off' | sudo tee -a /etc/network/interfaces

Cost Comparison

Setup	One-Time Cost	Monthly Cost	Notes
Pi 4 (2GB)	~$45	$0	+ power (~$5/yr)
Pi 4 (4GB)	~$55	$0	Recommended
Pi 5 (4GB)	~$60	$0	Best performance
Pi 5 (8GB)	~$80	$0	Overkill but future-proof
DigitalOcean	$0	$6/mo	$72/year
Hetzner	$0	€3.79/mo	~$50/year

Break-even: A Pi pays for itself in ~6-12 months vs cloud VPS.
