About ThumbmarkJS

ThumbmarkJS is a fair, privacy-friendly fingerprinting library built by developers for developers. Offered under an MIT license, it can be installed via NPM or loaded from jsDelivr, and with just a few lines of JavaScript, importing the UMD bundle and calling tm.get(), it returns a consistent 32-character thumbmark fingerprint. For small projects requiring higher accuracy, a free API version is available, while the Pro version scales indefinitely and cost-efficiently for large-scale applications. Without complex setup or invasive tracking, ThumbmarkJS has been integrated into over 60,000 websites, handling more than 1 billion identifications and 200 thousand downloads per month. It is free, open source, and has been designed as an alternative to FingerprintJS. It generates distinct, persistent device fingerprints using web APIs like canvas, audio, fonts, WebGL, and more, enabling identification of browsers across sessions.

In a similar way, the hardware and software configuration data of your machine collectively act as a unique fingerprint of your machine. Many third-party websites use the data as a means to identify you as an individual. The key is to get as much information as possible based on browser configurations and what data it can be collected. The collected digital fingerprint data includes browser version, system fonts, resolution, operating system, CPU class, language, WebGL, RAM, CPU, SSL, Media Device, Extensions, etc. the list is huge.

    "Just what we needed"

    5 out of 5 stars Posted 2026-08-17

    Pros: I really like the ease of integration with this. It's really straight forward and does exactly what it promises. The dashboard is informative and you can see exactly how many requests have been made. I also like the webhook functionality.

    Cons: It seems like the system is lacking a bit in detecting VPN connections and private browsing. Some VPN connections are not being detected, and private browsing is not something that we were able to get through this either, but we combined another service with this to get the full package.

    Overall: We were able to cut down heavily on account fraud by implementing this on our website. Previously, people were registering multiple accounts fraudulently, and we were able to now put a system in place to track when a request comes from the same machine. Really recommend using this software!
