WhatIP tool
See the browser and device information that websites can commonly observe when you visit.
This runs entirely in your browser. Nothing here is sent to a WhatIP server.
Signal count
An informational count of common browser signals, not a security rating.
What you should know
This tool reads standard information your browser makes available to any website you visit -- things like your browser and operating system, screen size, timezone, and language -- entirely inside your own browser using JavaScript. Nothing it displays is sent to WhatIP's server; it is a local look at what an ordinary site could observe about you.
Browsers share this information as part of normal web standards, mainly so sites can render correctly for your device and language. Individually, most of these details are common to large groups of visitors. Combined together, however, they can narrow down a specific browser closely enough to be used for tracking -- a technique known as browser fingerprinting.
Privacy-focused browsers and extensions can reduce fingerprinting by standardizing values like timezone and screen size across users, blocking known tracking scripts, or limiting what JavaScript APIs are allowed to report. This tool is meant to show you a realistic baseline of what is visible today, not to fix it for you.
