About UNDETECT.CLUB
The most comprehensive free browser fingerprint scanner. 32 modules. 100% in-browser. Zero data collected.
What Is UNDETECT.CLUB
UNDETECT.CLUB is a free, fully in-browser browser fingerprint and privacy scanner. It is the most comprehensive free tool of its kind, running 32 independent detection modules that analyze every trackable signal your browser exposes — including WebRTC leaks, canvas fingerprints, WebGL GPU data, audio fingerprints, bot signals, VM artifacts, font lists, and more.
Every test runs entirely in JavaScript within your browser. No fingerprint data is transmitted to any server. No account is required. The tool is completely free with no feature limits.
UNDETECT.CLUB is used by privacy-conscious individuals, VPN users verifying their setup, developers testing anti-detect browser configurations, security researchers, and anyone who wants to understand exactly what data their browser reveals to websites.

Who Uses UNDETECT.CLUB
Privacy-conscious individuals — Test how much your browser reveals and take steps to reduce your fingerprint.
VPN users — Verify your VPN is not leaking your real IP via WebRTC, and that your setup is working as expected.
Anti-detect browser users — Test whether Multilogin, GoLogin, AdsPower, or other tools are successfully masking your fingerprint.
Developers and QA teams — Test browser automation environments (Selenium, Playwright, Puppeteer) against bot detection signals.
Security researchers — Audit browser fingerprint attack surfaces and compare browser privacy implementations.
Tor and Brave users — Verify that privacy protections (canvas noise, WebGL randomization) are functioning correctly.
Privacy Policy
UNDETECT.CLUB collects zero user data. All 32 detection modules execute locally in your browser using standard JavaScript Web APIs. The results are displayed to you and never transmitted to our servers. The only external network request is an optional IP geolocation API call to display your public IP address — this is made to a third-party API and does not transmit your fingerprint data.
No cookies are set. No fingerprint profiles are stored. No analytics that identify individual users are deployed. The tool is built for privacy testing, so it must itself be private.
