Anti-Fingerprint Browser

Anti-Fingerprint Browser is a Chromium build that controls what the browser reports about the machine (GPU, canvas, audio, fonts, screen, hardware, timezone) instead of exposing a stable, unique fingerprint to every site.

Spoofing is done inside the browser engine rather than through injected JavaScript, so there are no Object.defineProperty wrappers for a page to detect. Each launch gets a random identity, or a reproducible one from an integer seed passed on the command line, so the same profile can present the same machine every time.

The changes are published as a readable patch series (one patch per feature) on top of ungoogled-chromium, so what is spoofed and how can be audited before running the binary. Prebuilt binaries (installer and portable zip) are on the GitHub Releases page.

For automation it works with standard CDP tooling (Playwright, Puppeteer, browser-use and similar) and adds custom CDP methods aimed at AI agents and scrapers, such as a one-call page snapshot of interactive elements, access to closed shadow roots, and batched human-like mouse paths and keystrokes.
