generative-bayesian-network

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

(async () => {
    const b = await chromium.launch({headless: false});
    const ctx = await b.newContext();

    const fingerprintGenerator = new FingerprintGenerator();
    const fingerprintInjector = new FingerprintInjector();

    const fingerprint = fingerprintGenerator.getFingerprint({
        'locales': ['cs-CZ'],           // setup your desired fingerprint features
        'operatingSystems': ['linux'],
    });
    await fingerprintInjector.attachFingerprintToPlaywright(ctx, fingerprint);

    // ...and enjoy your undercover browser while using the browser context as usual!
    const page = await ctx.newPage();
    await page.goto("https://apify.com");
})();

Performance

With ever-improving performance of antibot fingerprinting services, we use some of the industry-leading services to benchmark our performance. The following table shows how is the latest build of fingerprint-suite doing in tests provided by various open-source fingerprinting services.

The performace is evaluated using school-like grades (A being the best, F being the worst).
