UNAME

Your public IP address is the network address this browser exposes to websites right now. It usually identifies your current internet connection, not the exact device in your hand.

The city and ISP are approximate and can change when you switch networks, use mobile data, reconnect a VPN, or move behind a corporate gateway. uname.fyi does not proxy, store, log, or remember the lookup response.

Websites can often tell whether you are using a phone, tablet, or desktop computer. This helps them choose layouts, button sizes, menus, and other interface details that fit your screen and input method.

This is a friendly device type, not a precise hardware identity. Browsers do not always reveal an exact model, and some intentionally reduce these details for privacy.

Your user agent is the raw text string your browser sends to identify its browser family, rendering engine, operating system, and compatibility mode. It can look noisy because many tokens are historical and kept for older websites that expect them.

Some browsers reduce or freeze parts of this string for privacy, so treat it as a useful debugging signal rather than a complete device profile.

Your screen resolution is the display size reported to the browser. The value shown here uses CSS pixels, which are the practical units websites use for layouts, media queries, and responsive breakpoints.

Screen resolution can differ from the physical pixel count of the device because operating systems apply display scaling. Window size may also change independently when you resize a desktop browser, rotate a phone, or use split-screen mode.

This page shows the browser and operating system detected from your current session. It is a friendly summary websites may use for compatibility and support.

Use it when a website, support team, or developer asks which browser you are using. The value is shown only on this page and is not stored by uname.fyi.

Your browser version helps websites decide which features, security requirements, and compatibility fixes to use. Support teams may also ask for it when a page does not work as expected.

Some browsers reduce, freeze, or simplify version details for privacy and compatibility, so the value shown here is the version your browser chooses to expose.

This page shows whether your browser reports cookie support as enabled for this session. Websites use cookies to remember sign-ins, preferences, carts, and other small pieces of state between page loads.

A value of blocked usually means cookies are disabled by your browser, an extension, private browsing rules, or site settings. uname.fyi does not set, read, or store cookies; it only mirrors the browser setting shown by this API.

Websites use browser storage to remember logins, settings, carts, drafts, offline files, and app data.

This page only checks storage features available to uname.fyi, including cached files for this site if a service worker has saved any. Browsers do not let one website read storage saved by other websites. Temporary test values are removed immediately.

This page shows the color scheme preference your browser reports right now. Websites use this setting to choose dark or light themes automatically when they support system appearance preferences.

The value usually follows your operating system, browser, or device theme setting. It can change when you switch appearance modes, use scheduled dark mode, or override a site with an extension. uname.fyi only reads the preference locally and does not store it.

This page checks whether JavaScript is running in your browser right now. Websites use JavaScript for interactive features like menus, forms, maps, account pages, and live updates.

If JavaScript is disabled, the live value above will not update and the fallback message on this page will appear instead. uname.fyi does not store this setting; it only reflects whether the page script is able to run.

This page shows whether the browser reports touch input support for the current device. Websites use this signal to adjust tap targets, gestures, menus, and other interface details for touch screens.

Touch support is a capability signal, not a precise device identity. Some laptops, tablets, emulators, remote sessions, or privacy settings can make the reported value different from what you expect.

This page shows whether your browser currently reports an online or offline network state. Websites may use this signal to pause syncing, show offline messages, or retry network requests later.

The value does not guarantee that every website or server is reachable. Captive portals, firewalls, VPNs, flaky Wi-Fi, or blocked domains can still prevent requests even when the browser reports online.

This page shows whether your browser reports a preference for reduced motion. Websites use this setting to limit animation, parallax, transitions, and other motion effects when users prefer a calmer interface.

The value usually follows an accessibility setting in your operating system, browser, or device. uname.fyi only reads the preference locally and does not store it.

Your browser language is the preferred language or locale your browser shares with websites. Sites use it to choose translated content, date formats, number formats, and other regional defaults.

This value usually comes from your browser or device settings. It may be different from your current location, IP address, or timezone, especially if you use a VPN, travel often, or prefer a language from another region.

Your timezone is the regional time setting reported by the browser. Sites use it to format dates, schedule events, and decide how timestamps should appear locally.

This value comes from your device settings, not from your IP address. A VPN, remote desktop, travel setup, or manually changed clock setting can make your network location and browser timezone disagree.
