Browser Info
Instantly detect browser name, version, rendering engine, OS, screen resolution, language, and all capabilities online.
What browser information can this tool detect?
This tool detects comprehensive browser details including name and version, rendering engine (Blink, Gecko, WebKit), operating system, screen resolution and color depth, language settings, JavaScript engine, supported web APIs (WebGL, WebAssembly, Service Workers), cookie status, touch support, and many other capabilities.
How does browser detection work?
Browser detection uses multiple methods: parsing the navigator.userAgent string for basic identification, feature detection (checking if specific APIs exist), and analyzing navigator.platform and screen properties. Modern browsers also support Client Hints API for more accurate information.
Is my data sent to any server?
No. All detection happens 100% locally in your browser using JavaScript. No data is transmitted to any server, no cookies are set, and no tracking occurs. Your privacy is fully protected.
Why might browser detection be inaccurate?
Some browsers spoof their user agent string for compatibility (e.g., Edge appears as Chrome). Privacy-focused browsers may randomize certain properties. Feature detection is more reliable than user agent parsing alone, which is why this tool uses both methods.
What is a user agent string?
A user agent string is a text identifier sent by your browser to websites. It contains information about browser name, version, rendering engine, and operating system. Websites use it to deliver compatible content and optimize the browsing experience.
What is the difference between browser engine and rendering engine?
The rendering engine (Blink, Gecko, WebKit) handles displaying web pages by parsing HTML/CSS and painting pixels. The JavaScript engine (V8, SpiderMonkey, JavaScriptCore) executes JavaScript code. Together they form the browser's core technology stack.
How can I check my screen resolution?
This tool displays your screen resolution (e.g., 1920x1080), available screen area (excluding taskbar), color depth (bits per pixel), and device pixel ratio. This information helps developers optimize layouts for different displays.
What are browser capabilities and why do they matter?
Browser capabilities refer to supported web technologies and APIs like WebGL for 3D graphics, WebAssembly for high-performance code, Service Workers for offline functionality, and various HTML5 features. Knowing your browser's capabilities helps developers build compatible websites.
Can websites use this information to track me?
Browser fingerprinting uses combinations of browser properties (user agent, screen resolution, installed fonts, timezone) to create unique identifiers. This tool only displays your information locally without storing or transmitting data. Consider privacy-focused browsers or extensions that randomize fingerprints.
What is WebGL and how do I know if my browser supports it?
WebGL (Web Graphics Library) is a JavaScript API for rendering 2D and 3D graphics in the browser without plugins. This tool detects WebGL support and version (WebGL 1.0, 2.0). Most modern browsers support WebGL 2.0, which is based on OpenGL ES 3.0.
How to Use Browser Info
See what your browser reveals about itself: name, version, rendering engine, operating system, screen resolution, language, and supported capabilities. The report is generated locally and nothing is uploaded.
- Open the page and read the detected browser name and version at the top of the report.
- Check the rendering engine line to confirm whether you are running Blink, Gecko, or WebKit.
- Note the operating system and screen resolution entries; they are handy details for bug reports.
- Scroll through the capability list to verify which modern web APIs your browser supports.
- Compare the reported language with your system settings when debugging locale issues.
Attach a screenshot of this page to bug reports — it answers the version questions support teams usually ask first.
