Complete tool guide
Use this browser and device information checker to identify the browser, rendering engine, operating system, screen characteristics, input capabilities, locale, preferences, connection hints, security context, and user-agent string exposed to websites.
Your input is processed in the current browser tab and is not sent to the application server.
Open this page in the browser you want to inspect.
Review the detail cards, which update as you resize or rotate the window.
Copy or download the report to share it.
Shows the detected browser and version, rendering engine, operating system, device class or model, and platform. Detection uses browser-provided identifiers and may be generalized by privacy protections.
Viewport is the current page area; Screen is the browser-reported display size; Available screen excludes reserved system areas. Native resolution is estimated from screen size multiplied by device pixel ratio.
Pixel ratio explains high-density scaling. Color depth and gamut describe available color precision and range. Orientation reports the browser's current screen orientation and updates when supported.
Maximum touch points, pointer precision, and hover support describe input. Logical processors, approximate memory, and CPU architecture are capability hints—rounded or hidden on many browsers, not hardware benchmarks.
Language list and time zone reflect browser or system configuration. Color scheme, reduced motion, and contrast show accessibility and appearance preferences websites can adapt to.
Online status, connection type, effective network class, estimated downlink and round-trip time are browser hints, not a speed test. Data Saver, cookie availability, and secure context describe the current browser and page.
The user-agent string is the legacy identification text sent with requests. It is useful in support logs, but it can be frozen, reduced, or spoofed and should not be treated as definitive hardware identification.
Viewport, orientation, online state, and connection hints refresh when the browser reports a change. Resize the window, rotate the device, or change networks to watch supported values update.
The prepared plain-text report includes the core environment categories and is easier to attach to a bug or support request. Review it first, because it may contain details you do not want to share publicly.
Modern browsers deliberately hide or round some device details to limit fingerprinting. "Not exposed" means the browser will not report it here, not that the device lacks the feature.
Viewport size, orientation, online status, and connection hints refresh automatically when the browser reports a change, so you can resize the window and watch them update.
Memory and network figures are rounded hints rather than measurements. For real throughput, use the internet speed test instead.
No. Every value is read from your own browser and displayed in this tab. The report is only shared if you copy or download it yourself.
Screen size is reported in CSS pixels. On a high-density display the native resolution is the CSS size multiplied by the pixel ratio, which is shown alongside it.
Browsers built on Chromium often report a Chrome-based user-agent string, and privacy features can deliberately report a different one. The rendering engine line is usually the more reliable signal.
