How to use this tool
Overview
What Is My Browser - Free Browser & User Agent Checker shows exactly which browser you are using: name, version, rendering engine and operating system, plus display details like screen resolution, viewport size, pixel ratio and color depth. It also lists your language, timezone, cookie and Do Not Track settings, touch support and online status. Everything is detected locally from standard browser APIs — nothing is uploaded, and no external service is contacted. Use it to check whether your browser is up to date, to copy your user agent for support requests, or to see what information websites can read from your browser.Frequently asked questions
How do you detect my browser? +
The What Is My Browser - Free Browser & User Agent Checker reads the user agent string your browser sends with every request and parses it into a browser name, version and engine. No external service is used.
Why does my browser version matter? +
Outdated browsers miss security patches and may not support modern web features. This page shows your version so you can check whether an update is available.
Is detecting my browser a privacy problem? +
By itself, a browser name is not personal data. It becomes identifying when combined with other signals — see our browser fingerprint test to learn more.
Is this tool free and private? +
Yes — it is 100% free and everything is computed locally. Nothing is sent to 0Appz or any third party.
