@zaplier/sdk

Advanced privacy-first tracking SDK with session replay, heatmaps, and anti-adblock technology.

Makes a website visitor identifier from a browser fingerprint with enhanced session recording capabilities. Unlike cookies and local storage, fingerprint stays the same in incognito/private mode and even when browser data is purged. 100% cookieless analytics tracking with GDPR/LGPD compliance, advanced bot detection, session replay, and heatmaps.

✨ Features

• 🛡️ Privacy-First: 100% cookieless tracking using advanced fingerprinting
• 🎬 Session Replay: Record and replay user sessions with DOM mutation tracking
• 🔥 Heatmaps: Track clicks, scrolls, and user interactions
• 🚫 Anti-Adblock: Multiple transport methods to bypass adblockers
• 🤖 Bot Detection: Advanced bot and fraud detection
• 🌍 GDPR Compliant: Built-in GDPR mode and consent management

Alternatively you can install from CDN

<script src="https://cdn.jsdelivr.net/npm/@zaplier/sdk@1/dist/sdk.min.js" 
        data-token="your-workspace-token"
        data-heatmap="true"
        data-replay="true"></script>
<script>
  // SDK is automatically initialized from data attributes
  
  // Track custom events
  Zaplier.track("page_interaction", {
    element: "header_button",

    currency: "USD",
    items: [{ id: "product-123", name: "Product Name" }]
  });

  // Get visitor identifier
  console.log("Visitor ID:", Zaplier.getVisitorId());
</script>

Configuration Options

Zaplier.init({
  token: 'your-workspace-token',    // Required: Your workspace token
  heatmap: true,                    // Enable heatmap tracking
  replay: true,                     // Enable session replay
  debug: false,                     // Enable debug mode

Anti-Adblock Technology

The SDK automatically uses multiple transport methods to ensure data delivery:

1. Standard Fetch - Primary method
2. WebSocket - Real-time fallback

4. WebRTC - P2P data channel (experimental)

Note that you need to replace your-workspace-token with a workspace token from the dashboard.
