What is a browser fingerprint?

A browser fingerprint is a unique identifier assembled from dozens of browser and device signals — canvas rendering output, WebGL GPU data, installed fonts, screen resolution, timezone, language, audio processing characteristics, and more. Websites use fingerprinting to track and identify users even without cookies or login. Learn how it works →

What does UNDETECT.CLUB detect?

UNDETECT.CLUB runs 36 live detection modules entirely in your browser: WebRTC IP leak, canvas 2D fingerprint, WebGL GPU fingerprint, audio fingerprint, bot & automation signals, VM & headless browser detection, local port scan, system font enumeration, browser spoof detector, anti-fingerprint tool detection (Brave, Firefox RFP), Client Hints deep scan, WebGPU deep scan, security context analysis, CSS feature detection, CPU benchmark, and network latency probes.

Is my data sent anywhere?

No. All 36 detection modules run entirely client-side using browser JavaScript APIs. The only external request is a standard IP geolocation lookup to show your public IP address. No fingerprint hash, no scan results, and no personal data is ever sent to or stored on any server.

How to fix a WebRTC leak?

Disable WebRTC in your browser or use an extension like uBlock Origin (enable the WebRTC blocking option). Firefox users can set media.peerconnection.enabled to false in about:config. Most quality VPN browser extensions also include built-in WebRTC leak protection. Full step-by-step guide →

What does the uniqueness score mean?

The uniqueness score (0–100) shows how many fingerprint signals your browser exposes. A higher score means more tracking surface — your browser is easier to identify across sites. Score below 30 is good for privacy. Above 70 means you're highly trackable even in incognito mode.

Alternatives to BrowserLeaks & Pixelscan

UNDETECT.CLUB is the most comprehensive free alternative to browserleaks.com and pixelscan.net, combining all their features into a single scan — plus exclusive detectors: browser spoof detector, anti-fingerprint tool detection, CPU benchmark VM analysis, and Client Hints deep scan not found in older tools.
