OpenClaw on Raspberry Pi
A always-on AI agent server for $60–80 in hardware and ~$0.50/month in electricity. Pi 4 or Pi 5, running 24/7 silently.
Which Pi to get
Best Pi for OpenClaw. 2–3x faster than Pi 4. Handles local models lightly. Recommended.
Best if you want to run small local models (Phi-2, TinyLlama) alongside OpenClaw.
Solid choice. Slightly slower than Pi 5 but perfectly capable for API-based OpenClaw.
Works for API-based OpenClaw (Claude/GPT). Tight if you run anything else alongside it.
Possible but not recommended. Too slow for comfortable use. Use a Pi 4 minimum.
Setup guide
Flash Raspberry Pi OS (64-bit) or Ubuntu 22.04 Server to your SD card using Raspberry Pi Imager.
curl -fsSL https://deb.nodesource.com/setup_20.x | sudo -E bash - sudo apt install -y nodejs
sudo npm install -g openclaw
openclaw init
openclaw gateway start
sudo npm install -g pm2 pm2 start 'openclaw gateway start' --name openclaw pm2 startup pm2 save

| Mac Mini M4 (comparison) | ~10W | ~$0.72 |
| Always-on PC (comparison) | ~80W | ~$5.76 |
Raspberry Pi FAQ
Can Raspberry Pi run OpenClaw?
Yes. OpenClaw is lightweight Node.js software — it runs well on Raspberry Pi 4 or Pi 5. The Pi isn't doing AI computation (that's handled by Claude/GPT APIs), so even a Pi 4 with 4GB RAM handles it comfortably. Pi 5 is recommended for the best experience.
How much power does OpenClaw use on a Raspberry Pi?
Remarkably little. A Raspberry Pi 5 running OpenClaw uses roughly 5–7W under load. Running 24/7, that's about $0.40–0.50/month in electricity (at $0.12/kWh). Far less than a Mac Mini, and nothing compared to a full desktop PC.
Pi 4 vs Pi 5 for OpenClaw — which should I get?
Pi 5 if you're buying new — it's about $20 more and significantly faster. Pi 4 (4GB) if you already have one or find it used — it works fine for API-based OpenClaw. Neither will struggle with the OpenClaw workload.
Can Raspberry Pi run local AI models with OpenClaw?
Partially. Pi 5 (8GB) can run very small models like Phi-2 or TinyLlama via Ollama, but slowly. For serious local model use alongside OpenClaw, a Mac Mini M4 or a PC with a discrete GPU is the better choice. Pi is ideal when using Claude/GPT APIs.
How do I keep OpenClaw running on Pi after reboot?
Use PM2: npm install -g pm2, then pm2 start 'openclaw gateway start' --name openclaw, then pm2 startup && pm2 save. This creates a startup script that relaunches OpenClaw automatically whenever the Pi reboots or loses power.
Is Raspberry Pi or VPS better for running OpenClaw?
Depends on your situation. Pi wins on: zero monthly cost (after hardware), local network access, privacy. VPS wins on: reliability (no power cuts), accessibility from anywhere, no hardware setup. If you have reliable home power and internet, Pi is excellent. For maximum uptime, a VPS is better.
