🚀 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

🎓 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

🛡️ 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: Use playwright-stealth.js

Issue: 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
