What Browser Am I Using? Browser & Device Info Tool

What Browser Am I Using? Browser & Device Info at a Glance

Wondering what browser am I using right now? This page reads your browser, device, operating system, and system settings the moment it loads and lays them out in one organized view. It is the same information any website can already see about you, shown back to you in plain, readable form.

It covers everything from browser name and version to screen resolution, CPU cores, GPU, battery, network type, and accessibility preferences. A built-in User Agent parser also lets you paste any UA string and break it down into browser, OS, device, and engine.

Who is it for?

Web developers

Test browser detection, check feature support, and debug cross-browser issues without digging through dev tools.

IT & support staff

Gather a user's exact browser, OS, and hardware details fast when troubleshooting a reported problem.

QA testers

Capture browser and device details and export them straight into a bug report.

Privacy-aware users

See exactly what your browser exposes to the sites you visit, from User Agent to GPU.

Private by design: every detail is read locally with standard browser JavaScript APIs. Nothing is sent to a server, saved, or logged — your information stays in your browser.

How to Use Browser & Device Info

Read your info

Everything is detected automatically on load. Browse the Browser Info, Device & System, and Advanced Info sections, and hover the help icon on any row to learn what a value means.

Copy what you need

Hover a row and click its copy button for a single value, or use Copy All to grab everything as formatted text in one click.

Parse a User Agent

The User Agent field shows your current UA string. Paste any other string into it and click Parse User Agent to extract its browser, OS, device, and engine.

Export or refresh

Click Export JSON to download a structured file for a bug report, or Refresh to re-read everything after changing network, orientation, or window size.

Features

Browser Detection

Identifies your browser name, version, and rendering engine, plus cookie status, Do Not Track, vendor, platform, and a live online indicator.

Device & Operating System

Shows your OS, device type (desktop, mobile, or tablet), screen resolution, viewport size, pixel ratio, orientation, and touch support.

Hardware Information

Reports logical CPU cores, approximate device memory, GPU vendor and model via WebGL, and battery level and charging state where supported.

Network Information

Displays your connection type (wifi, cellular, ethernet) and estimated download speed in Mbps when the browser exposes them.

User Agent Parser

Shows your current User Agent and parses any string you paste into its browser, OS, device, and engine — handy for logs, reports, and analytics.

Export Options

Copy any single value, copy everything as formatted text, or export the full report as a structured JSON file.

Browser Feature Detection

Checks support for notifications, geolocation, service workers, WebGL, WebGPU, and the built-in PDF viewer.

System Preferences

Detects color scheme, reduced motion, contrast, pointer type, and reduced transparency so you can see the accessibility settings sites can adapt to.

Frequently Asked Questions

What browser am I using?

The Browser Info card answers this instantly: it reads your User Agent and browser APIs to show your browser name, version, and rendering engine the moment the page loads — no clicks needed.

How does this tool detect my browser and settings?

It uses standard browser JavaScript APIs — the User Agent string, navigator properties, WebGL, and media queries. This is the same data any website can already access; the tool just reads it locally and displays it. Nothing is sent anywhere.

What is a User Agent string?

A User Agent (UA) is a text identifier your browser sends to every site you visit. It encodes your browser name, version, OS, and device type. The format is cryptic, so the built-in parser breaks any UA string into readable browser, OS, device, and engine values.

What device and OS am I on?

The Device & System card classifies your device as desktop, mobile, or tablet and shows your operating system with its version where available, alongside screen resolution, pixel ratio, and touch support.

Why do some values show “N/A”?

Browsers support different APIs. Device Memory and Network Information are exposed mainly by Chrome and Edge, Battery Status may be blocked for privacy, and some browsers limit GPU details to prevent fingerprinting. When an API is unavailable, the tool shows “N/A” rather than guessing.

Is the CPU cores count accurate?

It reports logical processors from navigator.hardwareConcurrency, not physical cores. A 4-core CPU with hyper-threading shows as 8. Some browsers also cap this value for privacy.

Why does my GPU show as “Unknown” or generic?

GPU details come from WebGL, and some browsers hide the real renderer name to prevent fingerprinting. Firefox, for example, may report a generic name instead of your exact GPU model. That is a privacy feature, not a detection error.

Can websites see all this information about me?

Yes — everything shown here is reachable by any site through standard browser APIs. If fingerprinting concerns you, use browser privacy settings or extensions, or a browser with built-in fingerprinting protection. This tool only displays what is already visible.

How do I use this for a bug report?

Click Export JSON to download all your system details as a structured file you can attach to a report, or use Copy All to paste them as text. Either way developers get exact details about your environment.

Does this tool work offline?

Yes. Once the page has loaded, all detection runs locally in your browser. You can disconnect from the internet and still view your details — the Online status simply switches to “No”.
