🎯 Why This Scraper?

Most scrapers fail because they look like bots. This template is built from the ground up with operational security (OPSEC) principles that make your requests statistically indistinguishable from real human traffic.

🔥 The Competition is Amateur Hour

Feature	Basic Scrapers	This Template
Fingerprint Consistency	❌ Random per request	✅ Session-bound
Timezone/Locale	❌ Hardcoded or missing	✅ Dynamic CDP sync
WebRTC Leak	❌ Exposes real IP	✅ Fully patched
Request Timing	❌ Uniform random	✅ Gaussian distribution
Session Management	❌ Cookie-only	✅ Full identity rotation
Proxy Geo-Sync	❌ Mismatched	✅ Real-time alignment

🛡️ Stealth Features

1. Per-Session Fingerprint Binding

Each browser session maintains a consistent hardware fingerprint. Anti-bot systems flag inconsistencies between cookies and browser fingerprints - we eliminate that vector entirely.

createSessionFunction: (sessionPool) => {
    const session = new Session({ sessionPool });
    session.userData = { fingerprint: fingerprintGenerator.getFingerprint() };
    return session;
}

2. Chrome DevTools Protocol (CDP) Geo-Sync

We query the proxy's actual IP location and surgically override the browser's timezone, locale, and geolocation at the engine level. JavaScript tampering detection cannot catch this.

await client.send('Emulation.setTimezoneOverride', { timezoneId: geo.timezone });
await client.send('Emulation.setGeolocationOverride', { latitude: geo.lat, longitude: geo.lon });

3. WebRTC Leak Prevention

WebRTC can bypass your proxy and leak your real IP. We mock the RTCPeerConnection API to prevent this attack vector.

4. Gaussian Delay Distribution (Box-Muller Transform)

Uniform random delays are a bot signature. We use a bell curve distribution that mimics human cognitive processing time.

// Most delays cluster around 4.5s, rare outliers at 2s or 8s - just like a real human
const delay = getGaussianDelay(4500, 1500, 2000, 10000);

5. Aggressive Session Retirement

Zero tolerance for burnt sessions. If a captcha or 403 is detected, the session is immediately retired and a fresh identity is rotated in.

6. Resource Blocking

We abort images, stylesheets, and fonts - saving 400% bandwidth and preventing fingerprinting via render timing.

🚀 Quick Start

1. Clone and Configure

apify create my-stealth-scraper --template stealth-scraper-template
cd my-stealth-scraper

2. Customize Your Target

Edit src/main.js:

• Set your target URL
• Configure your extraction selectors
• Adjust delays for your target's sensitivity

3. Deploy

$apify push

4. Run with Residential Proxies (MANDATORY)

{
    "startUrls": ["https://your-target.com"],
    "proxyConfiguration": {
        "useApifyProxy": true,
        "apifyProxyGroups": ["RESIDENTIAL"]
    }
}

⚠️ Datacenter IPs are dead on arrival. Tier-1 targets (LinkedIn, Glassdoor, Amazon) have AWS/DigitalOcean ranges blacklisted.

---

📖 Input Schema

Field	Type	Required	Description
startUrls	Array	✅	URLs to scrape
proxyConfiguration	Object	✅	Residential proxies required
maxRequests	Number	❌	Maximum pages to scrape (default: 100)
maxConcurrency	Number	❌	Parallel browsers (default: 3)

---

🔧 Customization Guide

Adding Your Own Extraction Logic

async requestHandler({ page, request, log, pushData, session }) {
    // 1. Block detection is already handled
    
    // 2. Add your selectors
    const data = await page.evaluate(() => {
        return {
            title: document.querySelector('h1')?.innerText,
            content: document.querySelector('.content')?.innerText,
            // ... your selectors
        };
    });
    
    // 3. Push to dataset
    await pushData({
        ...data,
        url: request.url,
        scrapedAt: new Date().toISOString()
    });
}

Adjusting Stealth Parameters

// For paranoid targets (banks, ticketing)
maxErrorScore: 0.3,  // Even stricter
maxUsageCount: 3,    // Kill sessions faster

// For relaxed targets
maxErrorScore: 1,
maxUsageCount: 20,

💡 Pro Tips

The Scaling Philosophy

Don't make 1 browser go fast. Make 50 browsers go slow.

If you need 10,000 pages:

• ❌ 1 browser @ 100 req/min = BLOCKED
• ✅ 50 browsers @ 1 req/10s = Looks like 50 users browsing

Sticky Sessions for Multi-Step Flows

Don't rotate IP mid-login. Use session persistence:

sessionPoolOptions: {
    maxPoolSize: 50,
    persistStateKeyValueStoreId: 'my-sessions'
}

Use the Right Proxy Group

• RESIDENTIAL - General purpose stealth
• GOOGLE_SERP - Google specifically
• Don't mix them.
