About
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.

About
Fingerprint is a device intelligence platform that works across web and mobile applications to identify every visitor with industry-leading accuracy, even when they are anonymous. It helps businesses stop fraud, detect bots and AI agents, reduce friction for trusted users, and build safer, more seamless products. It recognizes returning browsers and mobile devices without relying on cookies or IP addresses, assigning each visitor a persistent visitor ID that remains stable even across incognito mode, VPN usage, cleared cookies, and tampered devices. Fingerprint combines the original fingerprinting library with more than 100 signals developed by its research team, including VPN detection, IP geolocation, high-activity device detection, raw device attributes, IP blocklist matching, geolocation spoofing, browser bot detection, rooted device detection, browser tampering detection, and other Smart Signals.
