System Requirements and Resource Comparison

Before you start installing OpenClaw or PicoClaw, you need to understand what hardware resources each requires. This chapter gives you a clear comparison so you can choose the right VPS plan and avoid frustrating performance issues.

OpenClaw Resource Requirements

OpenClaw is built on Node.js and designed to be a multi-channel AI gateway. Here is what you need to run it comfortably:

Minimum Requirements

Resource	Minimum	Recommended
RAM	1 GB	2 GB
CPU	1 core (1.0 GHz)	2 cores (2.0 GHz+)
Storage	5 GB SSD	10 GB SSD
Network	Stable internet	Low-latency connection

Why OpenClaw Needs More Resources

OpenClaw runs as a Node.js application, which means:

1. JavaScript Runtime Overhead: Node.js includes the V8 JavaScript engine, which uses memory for just-in-time compilation and garbage collection.

2. Multi-Channel Architecture: OpenClaw maintains WebSocket connections to multiple messaging platforms simultaneously (WhatsApp, Telegram, Discord, etc.). Each connection consumes memory.

3. Web Dashboard: The built-in control UI at port 18789 requires additional resources to serve the web interface.

4. Hot Reload: OpenClaw watches configuration files and reloads them automatically, which requires file system watchers and additional process management.

Real-World Resource Usage

Based on typical deployments:

Idle State:
- RAM: 400-600 MB
- CPU: 1-2% of one core

Active State (handling messages):
- RAM: 600 MB - 1.2 GB
- CPU: 5-15% of one core
- Network: Depends on media file transfers

The Bottom Line: You can run OpenClaw on a 1 GB VPS, but you will have little room for other services. A 2 GB VPS is the sweet spot for comfortable operation.

PicoClaw Resource Requirements

PicoClaw is written in Go and designed specifically for minimal resource consumption. Here is what you need:

Minimum Requirements

Resource	Minimum	Recommended
RAM	64 MB	256 MB
CPU	0.6 GHz single core	1 core (1.0 GHz)
Storage	100 MB	500 MB
Network	Basic internet	Stable connection

Why PicoClaw is So Efficient

PicoClaw achieves its tiny footprint through several design choices:

1. Compiled Binary: Go compiles to native machine code. There is no virtual machine or interpreter overhead like with Node.js or Python.

2. Efficient Concurrency: Go's goroutines are lightweight (start at 2 KB of stack space) compared to operating system threads.

3. Single Binary Deployment: Everything is contained in one executable file. No dependency resolution, no package management at runtime.

4. No Web Dashboard by Default: The core service does not include a web UI, reducing resource requirements significantly.

Real-World Resource Usage

Based on typical deployments:

Idle State:
- RAM: 8-12 MB
- CPU: 0.1% of one core

Active State (handling messages):
- RAM: 10-20 MB
- CPU: 1-5% of one core

With Heartbeat Tasks Running:
- RAM: 15-30 MB
- CPU: 5-10% during task execution

The Bottom Line: PicoClaw can run on almost anything. You could deploy it on a $5-6/month VPS (Hetzner CX11 or NetCup VPS 500 G12) and still have plenty of resources left for a web server, database, and other services.

Side-by-Side Comparison

Metric	OpenClaw	PicoClaw	Difference
Language	TypeScript/Node.js	Go	Go compiles to native code
RAM Usage	600 MB - 1.2 GB	8-30 MB	PicoClaw uses ~97% less RAM
Startup Time	10-30 seconds	<1 second	PicoClaw boots 20x faster
Binary Size	~100 MB (with Node)	~20 MB	PicoClaw is 5x smaller
Docker Image	~200 MB	~30 MB	PicoClaw images are 85% smaller
Hardware Cost	$6-20/month VPS	$5-16/month VPS	Depends on provider
Embedded Friendly	No	Yes	PicoClaw runs on $10 boards

Cost-Benefit Analysis: Which VPS Plan?

Let us look at actual VPS providers and what you get for your money. This analysis helps you make an informed decision.

For OpenClaw: 2 GB RAM VPS

Provider	Plan	RAM	CPU	Storage	Price/Month
NetCup	VPS 500 G12	4 GB	2 vCores	128 GB NVMe	~€4.87*
Hetzner	CX21	4 GB	2 vCores	40 GB NVMe	~€4.90
Hostinger	KVM 2	8 GB	2 vCores	100 GB SSD	~$19.99
DigitalOcean	Basic	2 GB	1 vCPU	50 GB SSD	$12.00

* Requires 12-month contract plus setup fee (~€4.87)

Note: NetCup VPS plans are frequently sold out. Check availability before planning your setup. Requires 12-month contract and setup fee.

Recommendation: NetCup VPS 500 G12 offers excellent value at €4.87/month with 4GB RAM and NVMe storage when available (requires 12-month contract plus setup fee). If unavailable, Hetzner CX21 at €4.90/month is the best alternative.

For PicoClaw: 1-4 GB RAM VPS

Provider	Plan	RAM	CPU	Storage	Price/Month
NetCup	VPS 500 G12	4 GB	2 vCores	128 GB NVMe	~€4.87*
Hetzner	CX11	2 GB	1 vCore	20 GB NVMe	~€5.34
Hostinger	KVM 1	4 GB	1 vCore	50 GB SSD	~$15.99
DigitalOcean	Basic	512 MB	1 vCPU	10 GB SSD	$4.00

* Requires 12-month contract plus setup fee (~€4.87)

Note: NetCup VPS 500 G12 (4GB RAM, 128GB NVMe) at €4.87/month with 12-month contract plus setup fee when available. Subject to availability.

Recommendation: Even the cheapest plans work perfectly. PicoClaw leaves plenty of resources for running a small website or API alongside it.

Using the /cost-benefit-principle Skill

If you have access to ThinkCodeShip Pro, you can use the /cost-benefit-principle skill to analyze your specific situation. This skill helps you determine:

1. Whether a VPS is better than buying hardware for your use case
2. The break-even point between different VPS providers
3. Total cost of ownership over 1, 2, or 3 years

Example Analysis:

Input: "Compare running PicoClaw on a $5/month VPS for 2 years
        versus buying a Raspberry Pi 5 with 8GB RAM"

Output: The VPS costs $120 over 2 years. The Raspberry Pi setup
        costs ~$150 upfront (board, case, power supply, SD card, cooling).

        However, the Pi requires:
        - Your time for setup and maintenance: ~10 hours valued at $50/hour = $500
        - Dealing with power outages and internet issues
        - No guaranteed uptime

        The VPS is the better choice for business-critical automation.

Checklist Before Proceeding

Before moving to the next chapter, ensure you have:

• Decided between OpenClaw and PicoClaw (or both)
• Selected a VPS provider and plan that meets requirements
• Budgeted for ongoing VPS costs
• Verified you have a payment method for VPS signup

Troubleshooting: My VPS Does Not Meet Requirements

If your VPS has less than 1 GB RAM:

• Use PicoClaw only (it will run comfortably)
• Consider upgrading your VPS plan
• Look into swap space configuration (temporary fix)

If you are on a shared hosting plan:

• You cannot run Docker or persistent processes
• Upgrade to a VPS (this guide requires one)
• Consider cloud alternatives like Railway or Fly.io

If you want to run both on the same VPS:

• Minimum 2 GB RAM recommended
• 4 GB RAM for comfortable operation
• Monitor resource usage with htop or docker stats
