World's best free browser fingerprinting library

ThumbmarkJS is an MIT-licensed browser fingerprinting library that produces stable fingerprints with 90% uniqueness. It works with normal and private browsing. ThumbmarkJS is a free, open‑source browser fingerprinting JavaScript library, designed as an alternative to FingerprintJS.

It supports both client-side-only installs via CDN and npm, with optional API integration for improved uniqueness.
