Browser Information

This Browser Information tool gathers the details your browser quietly exposes about itself and your device, then lays them out in one clean table. It reads your browser name and version, your operating system, the platform you're on, your preferred languages, your screen resolution and color depth, the live viewport size, the device pixel ratio, whether cookies are enabled, your Do Not Track preference, your online status, the number of CPU cores your device reports, its approximate memory, and whether the screen supports touch. Every value is read locally by JavaScript running in your own browser — nothing is uploaded, logged, or sent to any server.

These details are the same signals websites use to tailor layouts, pick the right assets, and debug compatibility problems. Seeing them in one place is handy when filing a bug report, checking that a device emulator or "user-agent switcher" works, or confirming which browser version you're really running. Because the reading happens on your device, the answer is instant and always reflects the exact browser and window you're using right now.

1. Open the tool. As soon as the page loads it reads your browser's own navigator, screen, and window values and fills in the table. Until that finishes you'll briefly see a "Detecting…" message.
2. Scan the table. Each row pairs a label with the value your browser reports, from browser and OS at the top down to touch support at the bottom.
3. Resize to watch the viewport update. The viewport row reflects your window's inner size and updates live as you drag the window smaller or larger.
4. Copy everything. Click Copy all as text to place the whole table on your clipboard as plain Label: value lines — ready to paste into a bug report, support chat, or compatibility form.
5. Re-open any time. Nothing is stored, so reloading always shows fresh values for your current browser and device.

The table combines two kinds of information. Some rows are parsed from your user-agent string — the browser name and version and the operating system are best-effort guesses derived from that text. The remaining rows come from dedicated browser properties:

• Platform — navigator.platform, a short label for your operating system family.
• Languages — navigator.languages, your ordered language preferences.
• Screen resolution and color depth — screen.width, screen.height, and screen.colorDepth.
• Viewport size — window.innerWidth and window.innerHeight, updated live on resize.
• Device pixel ratio — window.devicePixelRatio, higher on retina and high-DPI displays.
• Cookies enabled — navigator.cookieEnabled.
• Do Not Track — navigator.doNotTrack, if your browser exposes it.
• Online status — navigator.onLine.
• CPU cores — navigator.hardwareConcurrency, the number of logical processors reported.
• Device memory — navigator.deviceMemory, approximate RAM in gigabytes, when available.
• Touch support — derived from navigator.maxTouchPoints.

Modern browsers deliberately trim, freeze, or omit some of these values to reduce fingerprinting, so treat every reading as a strong hint rather than a guaranteed fact. Where a property isn't available, the tool shows "Unknown" instead of guessing.
