What it does
The Browser Fingerprint Viewer shows you exactly what any website can learn about your browser without a single cookie: your screen size, GPU, installed fonts, timezone, languages, CPU cores, and a dozen more signals. Each signal is classified by privacy risk (high, medium, or low) and the whole set is condensed into one SHA-256 fingerprint ID — the same kind of unique identifier trackers compute silently in the background.
It is educational, not tracking. Everything is read locally in your browser, hashed locally, and never stored or sent anywhere. Close the tab and it is gone.
How to use it
- Open the page — collection starts automatically; no button to press.
- Read your fingerprint ID badge at the top, and copy it with Copy ID if you want to compare machines.
- Scan the summary line: how many signals your browser exposes, split by risk level.
- Expand each category section (Hardware, Graphics, Network, Browser, Input) to see individual signals, their current values, and their risk badge.
- Hit Recompute after changing something (zoom level, system font, timezone) and watch the ID change.
- Read How unique am I? at the bottom for what the risk levels mean and how to resist fingerprinting.

- Private by construction: runs 100% client-side — no network request, no storage, no logging. Signals shown as “not available” mean your browser (or an extension) blocked that probe, which is a good sign.
- Why it matters: fingerprints identify you across sites and survive cookie clearing. EFF’s Cover Your Tracks research shows most browsers are unique on a combination of just a few of these signals.
