🎓 Best Practices

1. Try web_fetch First

If the site doesn't have dynamic loading, use OpenClaw's web_fetch tool—it's fastest.

2. Need JavaScript? Use Playwright Simple

If you need to wait for JavaScript rendering, use playwright-simple.js.

3. Getting Blocked? Use Stealth

If you encounter 403 or Cloudflare challenges, use playwright-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

🛡️ Anti-Bot Techniques Summary

Lessons learned from our testing:

✅ Effective Anti-Bot Measures

1. Hide navigator.webdriver — Essential

2. Realistic User-Agent — Use real devices (iPhone, Android)

3. Mimic Human Behavior — Random delays, scrolling

4. Avoid Framework Signatures — Crawlee, Selenium are easily detected

5. Use addInitScript (Playwright) — Inject before page load

❌ Ineffective Anti-Bot Measures

1. Only changing User-Agent — Not enough

2. Using high-level frameworks (Crawlee) — More easily detected

3. Docker isolation — Doesn't help with Cloudflare

---

🔍 Troubleshooting

Issue: 403 Forbidden

Solution: Use playwright-stealth.js

Issue: Cloudflare Challenge Page

Solution:

1. Increase wait time (10-15 seconds)

2. Try headless: false (headful mode sometimes has higher success rate)

3. Consider using proxy IPs

Issue: Blank Page

Solution:

1. Increase waitForTimeout

2. Use waitUntil: 'networkidle' or 'domcontentloaded'

3. Check if login is required
