Running your own AI agent doesn't require expensive hardware. The LLM processing happens in the cloud (via Claude, GPT-4, etc.), so your local machine just needs to run the agent software and coordinate tasks. Here's what actually works.
Understanding the Requirements
When you run OpenClaw or similar AI agent software, your hardware handles:
- Running the agent application (Node.js, Python, or Docker)
- Storing configuration and conversation history
- Making API calls to AI providers
- Running local tools (browser automation, file processing)
What your hardware does NOT do (unless you're running local models):
- The actual AI inference (thinking)
- GPU-intensive processing
This means requirements are modest for most use cases.
Option 1: Raspberry Pi
Cost: $50-100
Power: 5-15 watts
Best for: Always-on automation, low-traffic personal use
A Raspberry Pi 4 or 5 can run OpenClaw for personal automation:
| Model | RAM | Works For |
|-------|-----|-----------|
| Pi 4 (4GB) | 4GB | Basic automation, email triage |
| Pi 4 (8GB) | 8GB | More complex workflows |
| Pi 5 (8GB) | 8GB | Recommended for new setups |
Pros:
- Incredibly low power consumption
- Silent operation
- Small form factor
- Cheap to leave running 24/7
Cons:
- ARM architecture (some tools may not work)
- Limited processing power
- SD card reliability concerns (use SSD)
- Initial setup requires Linux knowledge
Recommended setup: Raspberry Pi 5 with 8GB RAM, NVMe SSD hat, and a good case with passive cooling.
Option 2: Mini PC
Cost: $150-400
Power: 15-65 watts
Best for: Home server, multiple agents, heavier workloads
Mini PCs like Intel NUC, Beelink, or Minisforum offer more power in a small package:
| Price Range | Typical Specs | Use Case |
|-------------|---------------|----------|
| $150-200 | N100, 8GB RAM | Personal automation |
| $200-300 | N100/i3, 16GB RAM | Small business, multiple workflows |
| $300-500 | i5/Ryzen 5, 32GB RAM | Heavy automation, local models |
Pros:
- x86 architecture (everything works)
- More RAM and storage options
- Can run multiple services
- Still relatively low power
Cons:
- More expensive than Pi
- Slightly higher power consumption
- May need active cooling (fan noise)
Recommended: Beelink or Minisforum with Intel N100, 16GB RAM, 500GB SSD. Around $200-250.
Option 3: Old Laptop or Desktop
Cost: Free (if you have one) to $100 used
Power: 30-150 watts
Best for: Getting started, testing
That old laptop collecting dust? It probably works:
Minimum specs:
- 4GB RAM (8GB preferred)
- 64GB storage (SSD strongly preferred)
- Any Intel/AMD processor from the last 10 years
Pros:
- Use what you already have
- Built-in battery backup (laptop)
- Full x86 compatibility
- Easy to set up
Cons:
- Higher power consumption
- Takes up space
- May be unreliable
- Laptop fans can be loud
Good for: Testing your setup before investing in dedicated hardware.
Option 4: NAS Device
Cost: $300-800
Power: 20-60 watts
Best for: Users who already have a NAS, combined storage + compute
Modern NAS devices from Synology, QNAP, or Asustor can run Docker containers:
Works well:
- Synology DS923+ and above
- QNAP with Intel/AMD processors
- Most models with 4GB+ RAM
Limitations:
- ARM-based NAS devices have compatibility issues
- Limited CPU power compared to dedicated hardware
- Shared resources with storage tasks
Verdict: If you already have a capable NAS, it can work. Don't buy one specifically for AI agents.
Option 5: Cloud VPS
Cost: $5-50/month
Power: Not your problem
Best for: Remote access, reliability, no hardware management
Instead of local hardware, rent a virtual server:
| Provider | Cheapest Plan | Good For |
|----------|---------------|----------|
| Hetzner | $4/month | Best value |
| DigitalOcean | $6/month | Good docs |
| Linode | $5/month | Reliable |
| Vultr | $6/month | Global locations |
| OpenClaw VPS | $39/month | Fully managed |
Pros:
- No hardware to maintain
- Always-on internet connection
- Easy to upgrade
- Professional reliability
Cons:
- Ongoing monthly cost
- Data leaves your premises
- Dependent on provider
- Requires some Linux knowledge (except managed options)
Recommended: Start with a $5-6/month VPS from Hetzner or DigitalOcean if you're comfortable with Linux. Use OpenClaw VPS if you want managed hosting without DevOps work.
Comparing Options
| Option | Cost | Power | Skill Level | Best For |
|--------|------|-------|-------------|----------|
| Raspberry Pi | $75 | 10W | Medium | Always-on, low power |
| Mini PC | $250 | 30W | Medium | Home server, flexibility |
| Old Computer | $0-100 | 80W | Low | Testing, getting started |
| NAS | $500 | 40W | Medium | Already have one |
| Cloud VPS | $5-50/mo | N/A | Medium-High | Reliability, remote access |
| Managed VPS | $39+/mo | N/A | Low | No technical skills |
What About Running Local LLMs?
If you want to run AI models locally (instead of using Claude or GPT-4 APIs), requirements change dramatically:
For small local models (7B parameters):
- 16GB RAM minimum
- Modern CPU or GPU with 8GB+ VRAM
For larger local models (70B parameters):
- 64GB+ RAM
- High-end GPU (RTX 4090, multiple GPUs)
- Enterprise-grade hardware
This is a different use case than running an AI agent. OpenClaw calls cloud APIs for AI inference, so you don't need this hardware unless you specifically want local models for privacy or cost reasons.
Power Consumption Matters
For always-on devices, power costs add up:
| Device | Watts | Monthly Cost (at $0.15/kWh) |
|--------|-------|----------------------------|
| Raspberry Pi 5 | 10W | $1.08 |
| Mini PC | 30W | $3.24 |
| Old Laptop | 50W | $5.40 |
| Desktop | 100W | $10.80 |
| Desktop + GPU | 200W | $21.60 |
A Raspberry Pi costs ~$13/year in electricity. A desktop might cost $130/year. Over several years, this adds up.
My Recommendations
Just Getting Started
Use an old laptop or computer you already have. Get OpenClaw running and understand your needs before buying hardware.
Personal Automation (Technical)
Raspberry Pi 5 with 8GB RAM and SSD. Low power, always-on, ~$100 total investment.
Personal Automation (Non-Technical)
Managed VPS like OpenClaw VPS. No hardware, no Linux, just works.
Small Business
Mini PC with 16GB RAM or a $20-40/month VPS. More headroom for growth.
Privacy-Focused
Local hardware (Pi or Mini PC) keeps data on your premises. Cloud options send data to third parties.
Summary
Running AI agents doesn't require expensive hardware. Most of the compute happens in the cloud. Your local hardware just coordinates tasks and runs tools.
Start with what you have. A basic computer from the last decade works fine for testing. If you want dedicated hardware, a $75 Raspberry Pi or $250 mini PC handles most personal automation needs.
For the easiest path, managed cloud hosting eliminates hardware decisions entirely. You trade monthly cost for simplicity.
