Browser Info Tool – See Your Browser & Device Details
Get detailed information about your browser and device.
How to use this browser info tool
- Open this page and your full set of browser and device properties is detected and displayed automatically
- Scroll through the list of properties, each shown as a labeled card with its current value
- Resize your browser window to see Window Width, Window Height, and related values update on reload
- Compare values like Screen Width/Height against Available Width/Height to see how much space system UI takes up
- Use the displayed values when reporting a bug, so the exact environment can be reproduced
- Check the Cookie Enabled, Online Status, and feature-support fields to confirm your browser's current capabilities
Frequently Asked Questions
What information is shown?
The tool displays various browser and device properties including screen dimensions, language, platform, and capabilities. This information is available to websites you visit.
Is this information private?
Most of this information is available to websites through JavaScript APIs. While it doesn't directly identify you, it can be used for browser fingerprinting.
Why do websites need this information?
Websites use this information to optimize content for your device, detect capabilities, and provide a better user experience. However, it can also be used for tracking.
Related Tools
A browser info tool gives you a complete snapshot of the technical details your browser exposes about itself, from screen dimensions and color depth to language, platform, and feature support. This is useful for web developers debugging layout or feature-detection issues, QA engineers documenting the exact environment a bug occurred in, privacy-conscious users wanting to see what their browser reveals to every site they visit, and support staff who need a user's environment details to reproduce a problem. Because dozens of properties are pulled together into one readable view, it saves the trouble of opening developer tools and running each check manually. Everything shown here is read directly from your own browser and never leaves your device.
What is browser info?
This tool reads a set of standard browser and device properties directly through JavaScript: navigator.userAgent, navigator.language, navigator.platform, navigator.cookieEnabled, and navigator.onLine for browser and connectivity details; screen.width, screen.height, screen.availWidth, screen.availHeight, screen.colorDepth, and screen.pixelDepth for display properties; window.innerWidth, window.innerHeight, and window.devicePixelRatio for the current browser window; and Intl.DateTimeFormat().resolvedOptions().timeZone plus Date().getTimezoneOffset() for timezone information. It also checks for the presence of APIs like geolocation, serviceWorker, and webdriver to report feature support. All of these values are standard properties any website can read through JavaScript, and this tool simply collects and displays them together without transmitting any of it anywhere.
Common use cases
- Web development debugging: Confirming exact screen, viewport, and pixel ratio values while diagnosing a responsive layout bug
- Bug reports and QA: Documenting the precise browser environment a defect was observed in, for engineers to reproduce it
- Privacy awareness: Seeing the full range of properties a website can read about your browser and device without asking permission
- Feature detection checks: Verifying whether APIs like Service Worker or Geolocation are available before relying on them in a project
- Automation and bot detection testing: Checking whether the webdriver property is exposed, which can reveal automated browser sessions
- Cross-device comparisons: Checking how color depth, pixel ratio, or timezone reporting differs between a phone, tablet, and desktop
Limitations and common mistakes
- Most of these properties are readable by any website via JavaScript, so this tool does not reveal anything websites cannot already see themselves
- Values like Screen Width and Height reflect the OS-reported display resolution, which can be inaccurate under display scaling or multi-monitor setups
- The WebDriver field only detects automation tools that expose the standard navigator.webdriver flag; more sophisticated automation can hide this
- Browser Language and Timezone reflect your system and browser settings, not your actual physical location
- Some fields, like Geolocation and Service Worker support, only indicate that the API exists in the browser, not that it is enabled or permitted by the user
