Detailed Comparison
Raspberry Pi 5 (8GB)
Best Overall$80 one-time
Plus ~$40 for accessories
Pros
- ✓Best performance of any Pi
- ✓PCIe for NVMe SSD (fast storage)
- ✓8GB RAM handles OpenClaw + extras
- ✓Active cooling keeps it stable
- ✓Extremely low power: ~8-12W
Cons
- ✗Active cooling required for 24/7
- ✗Needs SSD for reliability (not microSD)

Our verdict: The best Pi for OpenClaw. 8GB RAM means you'll never be resource-constrained. Get the official active cooler and an NVMe HAT with a 128GB SSD.
Raspberry Pi 5 (4GB)
Best Value$60 one-time
Plus ~$40 for accessories
Pros
- ✓Cheaper than 8GB model
- ✓4GB RAM is sufficient for OpenClaw
- ✓Same fast CPU as 8GB model
- ✓Very low power consumption
Cons
- ✗Less headroom than 8GB
- ✗Still needs SSD and cooling
- ✗4GB can feel tight if running other services
Our verdict: The sweet spot for most users. 4GB RAM handles OpenClaw comfortably. Save $20 vs 8GB and spend it on a good SSD.
Raspberry Pi 4 (4GB)
Budget Pick$45-55 one-time
Often on sale
Pros
- ✓Cheaper than Pi 5
- ✓Wide availability
- ✓Proven, stable platform
- ✓4GB RAM works for OpenClaw
Cons
- ✗Slower than Pi 5
- ✗No PCIe (USB 3 SSD only)
- ✗Being phased out for Pi 5
Our verdict: Still works fine for OpenClaw if you find one cheap. But for new builds, get the Pi 5 — faster CPU, NVMe support, better overall.
Frequently Asked Questions
Which Raspberry Pi is best for OpenClaw?
Raspberry Pi 5 (4GB) is the sweet spot — fast enough, 4GB RAM is sufficient, and $60 upfront. Get the 8GB model if you plan to run other services alongside OpenClaw.
Can I use microSD instead of an SSD?
Technically yes, but microSD cards fail quickly under 24/7 write loads. A microSD running OpenClaw continuously will typically fail within 3-12 months. Use an SSD — your data and uptime depend on it.
How do I keep OpenClaw running after reboot?
Set up OpenClaw as a systemd service. Add `sudo systemctl enable openclaw` after installation. It will auto-start on every reboot.
What's the monthly electricity cost?
A Pi 5 draws ~5-12W. At average US electricity rates ($0.15/kWh), running 24/7 costs about $0.65-$1.30/month. Extremely cheap.
The Bottom Line
The Raspberry Pi 5 (4GB) is the best OpenClaw Pi for most people. Add a good SSD, active cooling, and the official PSU. Total cost: ~$120. Monthly electricity: ~$1. It's the cheapest 24/7 OpenClaw setup available — if you're comfortable with Linux.
