What Browser Am I Using?

Your browser, its version, the operating system it runs on and every web API it supports — read the moment this page opens, and copied out as a support-ready report in one click.

Nothing here is uploaded. Every value is read inside your browser and is gone when you close the tab.

How to Check Your Browser and System

Everything on this page comes out of the browser itself — the line it sends to every site, the settings it reports about itself, and the objects it exposes to a page. Here is what each of those is worth.

What this page reads

The user agent string, the settings the browser reports about itself, and the properties it exposes on navigator. No plugin, no download, and no server: the report only goes anywhere if you copy it and paste it yourself.

Why the user agent is not the truth

Browsers have impersonated each other since the 1990s, which is why nearly all of them still call themselves Mozilla. Chrome now freezes most of the string and moves the real detail into Client Hints, which only Chromium answers; Safari freezes its version too. The name and version above are a reading of what the browser chose to send, not an inventory of what is installed.

Finding and updating your version

Support desks ask for this constantly. Chrome and Edge: menu, then Help and About — which also updates. Firefox: menu, then Help and About Firefox. Safari: the Safari menu, then About Safari, with updates through System Settings. On a phone the browser updates with the app store. If the version here disagrees with that screen, an extension or a privacy setting is rewriting the string.

No IP address, on purpose

Most "what is my browser" pages lead with your IP address and a rough location. Showing those means sending your request to a server and logging it there. Everything on this page is read locally and never transmitted, which is the same promise every other test on this site makes.

The report as a support ticket

Copy report puts the whole thing on the clipboard as plain text, in English whatever language the page is in, because the person reading it at the other end may not share yours. It carries everything the page shows: browser, engine, operating system, language and privacy settings, and every API this browser has and has not got.

Frequently Asked Questions

The card at the top of this page answers it: the browser name and version first, the operating system underneath. When a site asks you to check, that line is what it wants.
It sits next to the browser name above. To confirm from inside the browser: Chrome and Edge under Help and About, Firefox under Help and About Firefox, Safari under the Safari menu and About Safari. Those screens also start an update if one is waiting.
A line of text your browser sends with every request, describing itself to the site. It is decades of compatibility fictions stacked on each other, which is why the parsed name above is more useful than the raw string — and why the raw string is shown anyway, since that is what a support desk usually asks for.
Because the user agent cannot tell them apart: Windows 11 still reports 10.0 in that string. The true version arrives only through Client Hints, which Chromium browsers answer and others do not. Where the page can get it, the operating system row shows it.
Because reading it means sending your request to a server and having that server log it. Nothing on this page is transmitted; every value is read locally inside your browser.
No. The page reads the values, shows them, and forgets them when you close the tab. Nothing is stored and nothing is uploaded — if you want the report somewhere else, you copy or download it yourself.
The list checks that the browser exposes an API, not that the hardware behind it exists or that you have allowed it. getUserMedia() is there on a laptop with no camera, and navigator.bluetooth is there with the adapter switched off. Anything that needs a permission is only settled when you grant it.
