Lightweight Browser Fingerprint Library – Thumbmark.js

An open-source alternative to the well-known Fingerprint.js library.

ThumbmarkJS is a lightweight browser fingerprinting JavaScript library that creates a unique fingerprint of a user’s browser by collecting details like audio, canvas, and WebGL fingerprints, available fonts and plugins, screen size, timezone, and more.

How to use it:

1. Install & download.

# NPM
$ npm install thumbmarkjs

2. Import the Thumbmark.js library.

<script src="/path/to/dist/thumbmark.umd.js"></script>

3. Generate a fingerprint hash from browser & system attributes:

ThumbmarkJS.getFingerprint().then(
  function(fp) {
    console.log(fp);
  }
);

4. Determine which component(s) should be excluded from the fingerprint hash.

ThumbmarkJS.setOption('exclude', ['webgl', 'system.browser.version])
