fingerprint-generator

fingerprint-suite is a handcrafted assembly of tools for browser fingerprint generation and injection. Today's websites are increasingly using fingerprinting to track users and identify them. With the help of fingerprint-suite you can generate and inject browser fingerprints into your browser, allowing you to fly your scrapers under the radar.

Overview

fingerprint-suite is a modular toolkit for browser fingerprint generation and injection. It consists of the following npm packages, which you can use separately, or together:

• header-generator: generates configurable, realistic HTTP headers
• fingerprint-generator: generates realistic browser fingerprints, affecting the HTTP headers and browser JS APIs
• fingerprint-injector: injects browser fingerprints into your Playwright or Puppeteer managed browser instance
• generative-bayesian-network: our fast implementation of a Bayesian generative network used to generate realistic browser fingerprints

Quick start

The following example shows how to use the fingerprinting tools to camouflage your Playwright-managed Chromium instance.

const { firefox } = require('playwright');
const { FingerprintGenerator } = require('fingerprint-generator');
const { FingerprintInjector }  = require('fingerprint-injector');

(async () => {
    const fingerprintGenerator = new FingerprintGenerator();

    const browserFingerprintWithHeaders = fingerprintGenerator.getFingerprint({
        devices: ['desktop'],
        browsers: ['chrome'],
    });

    const fingerprintInjector = new FingerprintInjector();
    const { fingerprint } = browserFingerprintWithHeaders;

    const browser = await firefox.launch({ headless: false });

    // With certain properties, we need to inject the props into the context initialization
    const context = await browser.newContext({
        userAgent: fingerprint.userAgent,
        locale: fingerprint.navigator.language,
        viewport: fingerprint.screen,
    });
   
    // Attach the rest of the fingerprint
   await fingerprintInjector.attachFingerprintToPlaywright(context, browserFingerprintWithHeaders);

   const page = await context.newPage();
   // ... your code using `page` here
})();
