What Is My Browser
You are using
Detecting…
All detection runs locally in your browser. Nothing is uploaded.
How to use
- Open this page in the browser you want to identify — the result appears automatically at the top.
- Read the large headline for your browser name and version, then check the Details card for engine, OS, and device type.
- Use the Copy button to grab your full user agent string for a bug report or support ticket.
FAQ
What browser am I using right now?
The headline at the top of this page shows your browser name and version, detected from your current session — for example "Chrome 124" or "Safari 17.4". It updates whenever you reload the page.
How do I find my browser version?
Your full version is shown under the Version row in the Details card. The major number (the part before the first dot) is what most compatibility requirements like "Chrome 120+" refer to.
Is my browser up to date?
Compare the version shown here with the latest release for your browser. If your major version is several releases behind, open your browser's About page to update — outdated browsers miss security fixes.
What is a user agent string?
The user agent is the text your browser sends with every request to identify itself. It encodes the browser, engine, and OS. You can copy yours here to paste into logs or a User Agent Parser.
Why does my browser version look wrong?
Modern browsers freeze or reduce the user agent for privacy, so the reported version may be rounded or capped. The detection here reflects what the browser exposes, not necessarily the exact build.
Is any data sent to a server?
No. Detection runs entirely in your browser using standard Web APIs. Your browser details are never uploaded, logged, or stored.
Introduction
What Is My Browser answers a simple question instantly: which browser am I using, and what version is it? Open the page and the large headline shows your browser name and version right away — no settings menus, no digging through an About dialog.
Knowing your exact browser matters more than it seems. Support teams ask for it, web apps gate features behind minimum versions, and many "this site looks broken" problems trace back to an outdated or unusual browser. This tool reads that information directly from your current session and presents it in plain language.
What this tool detects
The result is grouped so you can scan it quickly:
| Field | What it tells you |
|---|---|
| Browser | The browser family — Chrome, Safari, Firefox, Edge, Opera, etc. |
| Version | The full version string, with the major number used for compatibility checks. |
| Engine | The layout/rendering engine (Blink, WebKit, Gecko) and its version. |
| Operating system | The OS the browser is running on (Windows, macOS, iOS, Android, Linux). |
| Device type | Whether you are on desktop, mobile, tablet, or another profile. |
| User agent | The raw string your browser sends to every website. |
How browser detection works
Your browser advertises itself through the user agent string and, on modern Chromium browsers, through User-Agent Client Hints. This tool parses that information the same way analytics and feature-detection scripts do, then formats it into readable rows.
Because the data comes from your live session, it reflects exactly what websites see when you visit them — including any privacy reductions your browser applies.
Common use cases
- Filing a bug report — paste your browser, version, and user agent so developers can reproduce the issue.
- Checking a minimum requirement — confirm you meet a "needs Chrome 120+" or "Safari 16+" gate before troubleshooting.
- Verifying an update — make sure a browser update actually took effect.
- Helping someone remotely — ask a non-technical user to open this page and read one line instead of navigating menus.
Best practices
- Run the check in the browser that has the problem — incognito windows and different profiles can report differently if extensions or settings differ.
- Treat the major version as the number that matters for compatibility; the trailing build digits rarely affect support requirements.
- If you need to analyze a user agent from someone else's logs instead of your own, use the user agent parser.
- For a complete picture of your environment — screen size, timezone, hardware — open the device info tool, or check what is my timezone for time-related settings.
