Debugging only, no fingerprint tracking

All checks run locally in the current browser. The tool does not call a backend, upload results, store history, or load remote scripts. Browser capability results are for debugging only and do not represent a complete fingerprint or security assessment.

Common uses

Compatibility triage

Confirm language, platform, viewport, pixel ratio, storage, Canvas, and WebGL support quickly.

Support context

Copy JSON into an internal troubleshooting note instead of describing the browser environment by hand.

Privacy-aware fallback

Plugin data and WebGL renderer details may be hidden by browsers or privacy extensions, so the page explains restricted results.

FAQ

Are results sent to a server?

No. The page only reads local browser APIs and shows the result in the current page.

Why is the plugin list empty?

Modern browsers limit navigator.plugins visibility, especially in private windows or strict anti-tracking modes.

Can this judge browser security?

No. This tool only shows browser-exposed environment and capability details. It is not a complete fingerprint, security score, or vulnerability assessment.
