Browser Info & Fingerprint

What is the Browser Info & Fingerprint?

Reads out the properties your own browser exposes about itself — User-Agent string, platform, screen resolution, CPU core count, and network connection info — and lists them in one place.

How it works

On load, the tool simply calls standard (and a few non-standard) Navigator and Window properties — things like navigator.userAgent, navigator.hardwareConcurrency, navigator.connection, and window.screen — and renders whatever values the browser returns. Some fields, like deviceMemory or connection details, aren't supported in every browser, so they show as Unknown when absent.

SysAdmin & security use cases

• »See exactly what a website can read about your browser without opening DevTools.
• »Compare how Chrome, Firefox, and Safari report properties like hardwareConcurrency or connection.effectiveType.
• »Verify a headless browser or CI test environment reports the platform and screen size you expect.
• »Check what a basic bot-detection script sees when it inspects navigator properties.
