What Is My Browser
Instantly detect your browser name, version, operating system, screen resolution, language, timezone, and supported web features — all from your browser.
What Is My Browser Tool Tutorial
This tool instantly identifies your browser name, version number, operating system, device type, screen resolution, language, timezone, and user-agent string. It also checks 14 browser features and displays a comprehensive details table with 20+ data points. Every detection runs on your machine through client-side JavaScript with no server calls.
What Is My Browser and How Auto Detection Works
When the page loads, the tool immediately scans your browser environment using two data sources. The primary source is the Client Hints API which provides a structured brands array with browser names and version numbers. The fallback is the User-Agent string parsed through regular expressions. The hero section at the top displays the detected browser icon, the full browser name, the version number, and a combined line showing your operating system and device type. All of this happens in under 50 milliseconds, giving you an instant answer to what is my browser without clicking any button or waiting for a server response.
What Is My Browser Name
The browser detection logic follows a priority chain that checks for specific browsers in a specific order to avoid false matches. Microsoft Edge is checked first because its User-Agent contains the word Chrome which would cause a false positive if Chrome detection ran first. The tool looks for Edge markers in both the brands array using hasBrand('Edge') and the User-Agent string using /Edg\//i. After Edge, it checks Brave using navigator.brave, then Opera, Yandex, Samsung Internet, UC Browser, Firefox, Safari, Chrome, Chromium, and finally Internet Explorer. Each detection method is documented in the details table so you always know which source identified your browser. This layered approach ensures the tool correctly identifies what is my browser name across all major modern browsers.
What Is My Browser Version
Version extraction pulls from multiple sources depending on the browser. For Chromium-based browsers, the version is extracted from the brands API using the getBrand() helper function. The User-Agent string serves as fallback with regex patterns like /Chrome\/([\d.]+)/ for Chrome, /Firefox\/([\d.]+)/ for Firefox, and /Version\/([\d.]+)/ for Safari. The tool also calls getHighEntropyValues(['fullVersionList']) asynchronously to get the precise version number from the browser. If the high-entropy version differs from the initial detection, the tool updates the display automatically. This dual-layer approach gives you an accurate what is my browser version result even when the initial brands array only provides a major version number.
What Is My Web Browser Version
The details table shows your browser version in a dedicated row alongside the detection method that was used to find it. If the Client Hints brands API was available and contained matching entries, the detection method column shows Client Hints. If the brands API was not available or did not contain a matching entry, the method falls back to User-Agent parsing. The primary proxy for extraction is the brands array which lists browser-software pairs recognized by the browser itself. This is more reliable than UA parsing because the browser provides structured data rather than a string that needs regex extraction. Understanding what is my web browser version through structured API data gives you confidence that the version number is accurate.
What Is My Chrome Browser Version
For Google Chrome specifically, the tool uses a dedicated detection branch that checks for the Google Chrome brand in the brands array using hasBrand('Google Chrome'). If the brands API is available and contains Google Chrome, the version comes from the brands entry. If the brands API is not available, the tool falls back to the User-Agent regex /Chrome\/([\d.]+)/ with an additional check that the UA does not contain Chromium to avoid false positives. Chrome version numbers use a four-part format like 124.0.6367.119, and the tool displays the full version string in both the hero section and the details table. This dedicated handling ensures what is my chrome browser version displays correctly even when other Chromium-based browsers are present on the same system.
What Is My Internet Browser Version
Internet Explorer and legacy browser detection uses the Trident engine marker and MSIE token in the User-Agent string. When the tool detects /Trident\/|MSIE/i in the UA, it runs a dedicated branch that extracts the version from (?:MSIE |rv:)([\d.]+). This regex handles both the MSIE format used in older IE versions and the rv: format used in IE 11. The tool displays Internet Explorer with a blue heart emoji and marks the engine as Trident. While modern browsers use the Client Hints API, IE relies entirely on User-Agent parsing since it predates the brands standard. This fallback ensures what is my internet browser version still provides accurate data for users on legacy Microsoft browsers.
What Is My Web Browser
The Re-Detect Browser button next to the hero section calls location.reload() which refreshes the page and triggers a fresh detection cycle. This is useful after browser updates or when switching between browser profiles. The Copy User-Agent button copies the full User-Agent string to your clipboard using navigator.clipboard.writeText(ua). The Copy button inside the User-Agent card section also calls the same function and provides a secondary access point. The mini Copy button inside the hero section uses a light-colored style with white text against the gradient hero background. These utility buttons make it easy to share your browser information with support teams or developers when troubleshooting issues related to what is my web browser.
What Is My Browser on This Computer
The operating system detection runs alongside browser identification using a dual-source approach similar to the browser detection system. The platform property from navigator.userAgentData provides structured OS names like Windows, macOS, iOS, Android, or Linux. If the Client Hints API is unavailable, fallback regex patterns extract the OS from the User-Agent string. Windows detection matches /Windows NT 10/i for Windows 10 and 11, /Windows NT 6.3/i for Windows 8.1, and /Windows NT 6.1/i for Windows 7. macOS detection extracts the version number from /Mac OS X ([\d_]+)/ and replaces underscores with dots. Android detection pulls the version from /Android ([\d.]+)/. This comprehensive OS detection tells you what is my browser on this computer including the exact OS version running underneath.
What Is My Default Browser
The device type detection distinguishes between Desktop, Mobile, and Tablet using both the mobile property from navigator.userAgentData and User-Agent regex patterns. If uad.mobile is true or the UA matches /Mobi|Android(?!.*Tablet)|iPhone/i, the device is classified as Mobile. Tablets are detected through /iPad|Tablet/i patterns. Desktop is the fallback for everything else. The device type appears in the hero section next to the OS name and is also listed as a dedicated row in the details table. Three stat cards below the hero show your screen resolution, viewport size, language, and timezone at a glance. This combined view helps you understand your full browser environment and identify what is my default browser on your current device.
What Is the Web Browser on My Computer
The details table contains over twenty rows of browser information organized in a structured table format. The Browser row shows the detected name, followed by the Version row, Detection Method row, and a raw UA Brands row that displays the full brands API data as a JSON string. Below these, the Operating System row shows the detected OS with version, the Device Type row shows Mobile, Tablet, or Desktop, and the Rendering Engine row identifies the browser engine. The Platform row shows the raw platform string, and screen-related rows cover Screen Resolution, Viewport Size, Device Pixel Ratio, and Color Depth. Hardware rows include CPU Cores and Device Memory. Locale rows include Language, Languages, and Timezone. Network and privacy rows cover Network Type, Touch Points, Cookies, and Do Not Track status. This table is the definitive answer to what is the web browser on my computer with every detail in one place.
What Is My Default Web Browser
The User-Agent card section displays the complete raw User-Agent string in a monospace font with a dark header that includes a clipboard icon and Copy button. The User-Agent string is the original browser identification mechanism that websites have used since the early days of the web. Modern browsers send a User-Agent string that typically includes the browser name, version, rendering engine, and operating system all in a single line of text. The tool displays this string exactly as the browser sends it, giving developers and support teams access to the raw data for troubleshooting. The card has a subtle pink-tinted background for easy readability. Viewing the raw UA helps verify what is my default web browser by showing the exact identification string your browser broadcasts to every website you visit.
What Is My Browser User Agent
The feature support sidebar sits on the right side of the layout and checks 14 browser capabilities in real time. Each feature is displayed as a row with the feature name on the left and a Yes/No badge on the right. JavaScript is always marked as Yes since the tool itself runs on JavaScript. Cookies detection checks navigator.cookieEnabled. Touch Screen detection checks if maxTouchPoints is greater than zero. WebGL detection checks for window.WebGLRenderingContext and WebGL 2 checks for window.WebGL2RenderingContext. Service Workers checks for serviceWorker in navigator, Local Storage checks for the localStorage object, and IndexedDB checks for window.indexedDB. Web Workers, Geolocation, Notifications, and Bluetooth all use similar existence checks. The Do Not Track row checks navigator.doNotTrack and the Online row checks navigator.onLine. These feature checks complement what is my browser user agent data by showing what your browser can actually do.
What Is My Browser Language
Language detection reads from navigator.language for the primary language and navigator.languages for the full language preferences array. The primary language appears as a stat card with the label Language showing a value like en-US or hi-IN. The full languages array is displayed as a comma-separated list in the details table under the Languages row. The language detection is purely client-side and reads the browser locale settings that the user configured in their operating system or browser preferences. This information helps websites serve content in the appropriate language. The stat card uses the same grid layout as the other three cards, making it easy to scan your what is my browser language setting alongside your other browser statistics.
What Is My Browser Timezone
Timezone detection uses the Intl API through Intl.DateTimeFormat().resolvedOptions().timeZone to get the IANA timezone identifier such as America/New_York or Asia/Kolkata. The tool extracts the city portion after the forward slash and replaces underscores with spaces for a cleaner display. The timezone stat card shows just the city name like New York or Kolkata while the details table shows the full IANA timezone string. This timezone information is purely client-side and reflects the user's system timezone configuration. The timezone stat card is the fourth card in the stats grid alongside resolution, viewport, and language. Checking what is my browser timezone helps you verify that your system timezone settings are correctly configured for your location.
What Is My Browser Resolution
Screen resolution and viewport size are detected using the Screen and Window APIs. The screen resolution stat card displays the full hardware resolution using screen.width and screen.height separated by a multiplication sign. The viewport stat card shows the browser window inner dimensions using innerWidth and innerHeight. These two values differ because the screen resolution represents your monitor's physical pixel count while the viewport represents the available area inside your browser window minus toolbars and panels. The details table also includes a Device Pixel Ratio row using devicePixelRatio and a Color Depth row using screen.colorDepth. The DPR value tells you how many physical pixels each CSS pixel occupies, which is essential for understanding what is my browser resolution on high-density Retina or HiDPI displays.
What Is My Browser Info
The full details table provides over twenty data rows that cover every aspect of your browser environment. Each row has an uppercase label on the left and a value on the right rendered in a monospace font. The table header displays a computer emoji with the label Full Browser Details. Rows cover Browser Name, Version, Detection Method, raw UA Brands data, Operating System, Device Type, Rendering Engine, Platform, Screen Resolution, Viewport Size, Device Pixel Ratio, Color Depth, CPU Cores, Device Memory, Language, Languages, Timezone, Network Type, Touch Points, Cookies Status, and Do Not Track Status. Hovering over any row highlights it with a rose-tinted background for easy scanning. After the initial render, the tool asynchronously adds Architecture and Device Model rows when high-entropy client hints data becomes available. This table gives you complete what is my browser info in a single scannable view.
What Is Wave Browser on My Computer
Less common browsers like Wave Browser, which is a Chromium-based browser built around productivity features, are handled through the generic Chromium detection branch. When the tool encounters a browser that does not match any of the specific detection patterns for Edge, Chrome, Firefox, Safari, Opera, Brave, Yandex, Samsung Internet, UC Browser, or Internet Explorer, it falls through to the Chromium detection. The Chromium branch checks for hasBrand('Chromium') in the brands array or /Chromium\//i in the User-Agent. If neither matches, the tool returns Unknown Browser with a globe emoji. The brands array typically shows Chromium-based browsers in the raw UA Brands row even when the specific browser name is not recognized. This catch-all logic ensures that even less common browsers like Wave are properly identified when someone wants to check what is wave browser on my computer.
Async Detection and High-Entropy Data
After the initial detection finishes, the tool runs two asynchronous operations to enhance the results. The Brave detection calls navigator.brave.isBrave() which returns a promise. If the promise resolves to true, the tool updates the browser object to Brave Browser and re-renders the display. The high-entropy client hints call uses navigator.userAgentData.getHighEntropyValues(['fullVersionList','architecture','bitness','model']) to fetch detailed hardware information. The fullVersionList provides the complete browser version number which may be more precise than the initial brands version. The architecture and bitness values are added as a new Architecture row in the details table. The device model, if available, is added as a Device Model row. These async updates improve the accuracy of what is my browser info without requiring a page reload.
Practical Applications and Use Cases
Web developers use this tool to quickly verify their browser environment before testing new features. Support teams ask users to check their browser information when troubleshooting issues. Privacy-conscious users check the Do Not Track and Feature Support sections to see what data their browser exposes. Designers use the screen resolution and viewport data to test responsive layouts. SEO specialists check the browser language and timezone settings to verify localization configurations. Anyone troubleshooting a website issue can use the Copy User-Agent button to share their complete browser identification with support teams. The stat cards provide instant answers while the details table offers depth when needed. These practical applications make the tool useful for beginners who just want to know what is my default browser and professionals who need detailed technical data.

For users behind corporate proxies or VPNs, the tool still works correctly because it never makes external network requests. The entire detection runs in under 100 milliseconds with additional async refinements arriving within a few hundred milliseconds. This instant, private, comprehensive browser detection makes the tool the fastest way to get complete what is my web browser version and environment details.
Frequently Asked Questions
navigator.userAgent property returns the User-Agent string as a local string value. The navigator.userAgentData API provides a structured brands array and platform information. The Intl.DateTimeFormat API returns your timezone from local system settings. The Screen and Window APIs read your display dimensions from your operating system. None of these APIs make network requests. The tool simply reads these local properties and displays them on the page using DOM manipulation. All processing, parsing, and rendering happens inside your browser tab with zero data transmitted to any server. You can verify this by checking your browser developer tools network tab while the tool runs.navigator.userAgentData.brands, provides browser information as a structured JavaScript array. Each entry in the array contains a brand property with the browser name and a version property with the version string. This structured data is easier to parse and more reliable than string matching. The User-Agent string is a single text string that browsers have sent since the early web. It contains the same information but requires regular expression parsing to extract individual values. The User-Agent string can also be modified by browser extensions or enterprise policies, which makes it less reliable. The tool tries the Client Hints API first and falls back to User-Agent parsing when the API is unavailable. The details table shows which method was used so you know the source of your detection data.navigator.brave API that no other browser offers. Opera, Yandex, Samsung Internet, and UC Browser are checked after Brave because they use specific UA tokens. Firefox and Safari use distinct engine markers that are unlikely to conflict with Chrome-based browsers. Chrome and Chromium are checked near the end as a catch-all for Blink-based browsers. Internet Explorer is checked last using Trident markers. This ordering ensures every browser receives its correct identification.navigator.brave.isBrave() which is an async method that returns a promise. If the user is running Brave Browser, this method resolves to true and the tool updates the hero section and details table to show Brave instead of Chrome. The high-entropy API call requests additional details through navigator.userAgentData.getHighEntropyValues() with parameters for fullVersionList, architecture, bitness, and model. This data provides the complete browser version number which may be more precise than the initial detection. It also reveals the CPU architecture like x86 or ARM, the bitness like 64-bit or 32-bit, and the device model on mobile devices. These refinements appear automatically within about 200 milliseconds of the page loading.
