# How to Monitor Visual Changes with OpenClaw

OpenClaw automates visual change monitoring as a scheduled batch operation, capturing screenshots of your critical pages on a regular cadence and generating structured diff reports. Output includes pixel-level change detection, organized comparison archives, and machine-readable change logs for integration into alerting systems.

## Setup

openclaw mcp add toolrouter -- npx -y toolrouter-mcp

## Steps

1. Connect ToolRouter: openclaw mcp add toolrouter -- npx -y toolrouter-mcp
2. Ask OpenClaw: "Capture a baseline screenshot of example.com"
3. Later: "Capture a new screenshot and compare with the previous one"
4. OpenClaw identifies visual differences between captures
5. Investigate any unintended changes flagged in the comparison

## Example Prompt

```
Capture our homepage now and again next week. Let me know if anything changes visually.
```

## Tips

- Establish a regular monitoring cadence -- weekly for most pages, daily for critical ones
- Focus monitoring on pages that change frequently or have the most traffic
- Keep a visual changelog alongside your code changelog
