Browser Fingerprint Test

Find weak browser fingerprint inconsistencies that can make a privacy or proxy environment look unusual.

What this checks

  • Browser-reported identity signals such as user agent, platform, vendor, language list, timezone, Do Not Track, and WebDriver state.
  • Rendering and capability signals including canvas hash, WebGL vendor and renderer, audio hash, WebGPU support, WebRTC API support, plugin count, and MIME type count.
  • Storage and hardware availability signals such as cookies, temporary local and session storage probes, IndexedDB API presence, screen size, viewport, pixel ratio, touch points, CPU threads, and device memory when exposed.

How to interpret results

  • Lower exposure means fewer distinctive or inconsistent signals were available in the current browser session.
  • Moderate or elevated exposure usually means normal browser APIs returned enough identity, rendering, hardware, or storage signals to contribute to fingerprinting.
  • Danger findings highlight strong automation indicators such as navigator.webdriver or headless user-agent markers, but they are diagnostic hints rather than definitive judgments.

Common issues

  • Privacy extensions and hardened browsers may block canvas, WebGL, audio, or storage probes, which can appear as unsupported or unavailable signals.
  • Timezone, platform, language, and WebGL strings can look inconsistent during travel, remote desktop use, browser automation, or proxy profile testing.
  • Some browser APIs are intentionally missing on mobile, locked-down enterprise browsers, or browsers with strict anti-fingerprinting settings.

Privacy note

The browser fingerprint test is client-only. It does not read cookie values, localStorage or sessionStorage contents, camera or microphone labels, or send fingerprint results to the server.

Frequently Asked Questions

Does this browser fingerprint test send my fingerprint to the server?

No. The v1 checker runs in the browser and summarizes current-session signals locally. It does not create a report, history record, or server-side fingerprint database.

What signals does the test collect?

It checks browser-reported identity, timezone, languages, screen and viewport size, color depth, pixel ratio, touch support, hardware hints, storage availability, plugin and MIME counts, canvas, WebGL, audio, WebGPU support, and automation hints.

Do warnings mean I am being detected as a bot?

No. Warnings are weak diagnostic hints. Compare them with IP, DNS, WebRTC, proxy, and VPN checks before drawing conclusions about a browser profile.
