A Playwright-based web scraping OpenClaw Skill with anti-bot protection. Choose the best approach based on the target website's anti-bot level.
🎯 Use Case Matrix
| Target Website | Anti-Bot Level | Recommended Method | Script |
|---|---|---|---|
| Regular Sites | Low | web_fetch tool | N/A (built-in) |
| Dynamic Sites | Medium | Playwright Simple | scripts/playwright-simple.js |
| Cloudflare Protected | High | Playwright Stealth ⭐ | scripts/playwright-stealth.js |
| YouTube | Special | deep-scraper | Install separately |
| Special | reddit-scraper | Install separately |
📦 Installation
cd playwright-scraper-skill
npm install
npx playwright install chromium
🚀 Quick Start
1️⃣ Simple Sites (No Anti-Bot)
Use OpenClaw's built-in web_fetch tool:
# Invoke directly in OpenClaw
Hey, fetch me the content from https://example.com
2️⃣ Dynamic Sites (Requires JavaScript)
Use Playwright Simple:
node scripts/playwright-simple.js "https://example.com"
Example output:
{
"url": "https://example.com",
"title": "Example Domain",
"content": "...",
"elapsedSeconds": "3.45"
}
3️⃣ Anti-Bot Protected Sites (Cloudflare etc.)
Use Playwright Stealth:
node scripts/playwright-stealth.js "https://m.discuss.com.hk/#hot"
Features:
- Hide automation markers (
navigator.webdriver = false) - Realistic User-Agent (iPhone, Android)
- Random delays to mimic human behavior
- Screenshot and HTML saving support
4️⃣ YouTube Video Transcripts
Use deep-scraper (install separately):
# Install deep-scraper skill
npx clawhub install deep-scraper# Use it
cd skills/deep-scraper
node assets/youtube_handler.js "https://www.youtube.com/watch?v=VIDEO_ID"
📖 Script Descriptions
scripts/playwright-simple.js
- Use Case: Regular dynamic websites

scripts/playwright-stealth.js ⭐
- Use Case: Sites with Cloudflare or anti-bot protection
- Speed: Medium (5-20 seconds)
- Anti-Bot: Medium-High (hides automation, realistic UA)

- Verified: 100% success on Discuss.com.hk
🎓 Best Practices
1. Try web_fetch First
If the site doesn't have dynamic loading, use OpenClaw'sweb_fetch tool—it's fastest.2. Need JavaScript? Use Playwright Simple
If you need to wait for JavaScript rendering, useplaywright-simple.js.3. Getting Blocked? Use Stealth
If you encounter 403 or Cloudflare challenges, useplaywright-stealth.js.4. Special Sites Need Specialized Skills
- YouTube → deep-scraper
- Reddit → reddit-scraper
- Twitter → bird skill
🔧 Customization
All scripts support environment variables:
# Set screenshot path
SCREENSHOT_PATH=/path/to/screenshot.png node scripts/playwright-stealth.js URL# Set wait time (milliseconds)
WAIT_TIME=10000 node scripts/playwright-simple.js URL
# Enable headful mode (show browser)
HEADLESS=false node scripts/playwright-stealth.js URL
# Save HTML
SAVE_HTML=true node scripts/playwright-stealth.js URL
# Custom User-Agent
USER_AGENT="Mozilla/5.0 ..." node scripts/playwright-stealth.js URL

🛡️ Anti-Bot Techniques Summary
Lessons learned from our testing:
✅ Effective Anti-Bot Measures
- Hide
navigator.webdriver— Essential - Realistic User-Agent — Use real devices (iPhone, Android)
- Mimic Human Behavior — Random delays, scrolling
- Avoid Framework Signatures — Crawlee, Selenium are easily detected
- Use
addInitScript(Playwright) — Inject before page load
❌ Ineffective Anti-Bot Measures
- Only changing User-Agent — Not enough
- Using high-level frameworks (Crawlee) — More easily detected
- Docker isolation — Doesn't help with Cloudflare
🔍 Troubleshooting
Issue: 403 Forbidden
Solution: Useplaywright-stealth.jsIssue: Cloudflare Challenge Page
Solution:- Increase wait time (10-15 seconds)
- Try
headless: false(headful mode sometimes has higher success rate) - Consider using proxy IPs
Issue: Blank Page
Solution:- Increase
waitForTimeout - Use
waitUntil: 'networkidle'or'domcontentloaded' - Check if login is required
