Makes a website visitor identifier from a browser fingerprint. 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 and advanced bot detection.

Quick start

Get a workspace token:

1. Register a new account at rabbitracker.com/signup
2. After registration go to the dashboard and create a new workspace
3. Go to the "API Keys" page, create and copy your workspace token

Install from NPM

npm i @rabbitracker/sdk
# or
yarn add @rabbitracker/sdk

import RabbitTrackerSDK from "@rabbitracker/sdk";

// Initialize an agent at application startup.
const tracker = new RabbitTrackerSDK({
  token: "your-workspace-token",
  debug: true, // Enable for development
});

// Track page views (automatic)
// tracker.trackPageView() is called automatically

// Track conversions
tracker.trackPurchase({
  value: 99.99,
  currency: "USD",
  productId: "product-123",
});

// Track custom events
tracker.trackCustomEvent("button_click", {
  button_id: "signup",
  page: "homepage",
});

// Get visitor data
console.log("Visitor ID:", tracker.getUserData().fingerprint);

Alternatively you can install from CDN

Note: Installing via a script tag may interfere with SDK functionality for users with ad blockers enabled.

<script src="https://cdn.jsdelivr.net/npm/@rabbitracker/sdk@3/dist/sdk.min.js"></script>
<script>
  // Initialize the agent at application startup.
  const tracker = new RabbitTracker({
    token: "your-workspace-token",
  });

  // Track custom events
  tracker.trackCustomEvent("page_interaction", {
    element: "header_button",
    action: "click",
  });

  // Get visitor identifier
  const userData = tracker.getUserData();
  console.log("Visitor ID:", userData.fingerprint);
</script>

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