What Browser Am I Using?

Your browser, its version, the operating system and the web APIs it supports, shown as soon as the page opens. Copy it all as a report in one click.

Everything is read in your browser. Nothing is uploaded.

How to Check Your Browser and System

Everything on this page comes from the browser: the user agent it sends to sites, the settings it reports and the APIs it exposes.

What this page reads

The user agent string, the settings the browser reports and the properties on navigator. No plugin, download or server. The report goes nowhere unless you copy it.

Why the user agent can be wrong

Browsers have copied each other's user agent since the 1990s, so nearly all of them still call themselves Mozilla. Chrome and Safari now freeze most of the string, and only Chromium browsers send the real details through Client Hints. The name and version above are what the browser reports about itself.

Finding and updating your version

Chrome and Edge: menu > Help > About, which also installs updates. Firefox: menu > Help > About Firefox. Safari: Safari menu > About Safari; updates come through System Settings. On a phone, update the browser in the app store. If the version here differs from that screen, an extension or privacy setting is changing the user agent.

Why there's no IP address

Most "what is my browser" pages show your IP address and location. That requires sending your request to a server that logs it. This page reads everything locally and sends nothing.

Sending the report to support

Copy report puts everything on the page on the clipboard as plain text: browser, engine, operating system, language and privacy settings, and the list of supported APIs. The report is always in English, so any support team can read it.

No. Nothing is stored or uploaded, and the values are gone when you close the tab. To share the report, copy or download it.
