Browser Detection
Find out what web browser you're using and its version number.
Your web browser is the application you use to access websites. Common browsers include Chrome, Firefox, Safari, and Edge. Knowing your browser and version helps with troubleshooting, compatibility testing, and security updates.
Your browser version determines what websites and web applications work correctly on your device. Modern features like WebGL, WebRTC, and advanced CSS require up-to-date browsers.
Security is another crucial factor — older browser versions may have known vulnerabilities that hackers can exploit. Most browsers update automatically, but it's good to verify you're current.
Detection works by analyzing the user agent string — a text identifier sent to every website you visit. This string reveals application type, version, platform, and rendering engine. Sites use it to serve compatible content and optimize layout for your specific configuration. No files or system settings are accessed during detection.
We parse that string in your browser and match the major version against a reference table of the latest stable releases. Nothing is uploaded. Some browsers — mobile Safari and embedded WebViews in particular — report frozen or stripped versions, which is why a version can occasionally read as unknown.
Extensions and private-browsing modes do not change what this reports. Your browser identity is attached to every request you make, whether or not a window is private.
Need to identify the web application you're using to access the internet? This free detection tool instantly reveals browser name, version, and rendering engine — essential information for technical support, software compatibility, and security verification.
Keeping software current is critical for protection against known vulnerabilities. Updates deliver security patches, performance optimizations, and support for modern web technologies like WebGL, WebRTC, and advanced CSS features. An outdated version may expose you to exploits and break functionality on contemporary websites.
Each major application offers distinct strengths: Chrome leads in extension ecosystem and developer tools; Firefox prioritizes privacy with Enhanced Tracking Protection; Safari optimizes battery life on Apple hardware; Edge integrates deeply with Windows features. Knowing which you're running helps locate browser-specific settings and troubleshoot compatibility issues.
Common use cases include verifying updates installed correctly, providing accurate details to support teams, testing cross-browser compatibility during web development, and diagnosing rendering inconsistencies. IT professionals rely on accurate identification when debugging layout or functionality problems.
Works instantly on desktop, laptop, tablet, and mobile devices across all major platforms. No registration or downloads required — bookmark it for quick reference whenever you need version verification.
Browser updates include security patches, performance improvements, and new features. Outdated browsers are vulnerable to security exploits and may not display modern websites correctly.
A user agent is a string of text your browser sends to websites identifying itself. It includes your browser name, version, operating system, and sometimes device information.
Google Chrome is currently the most popular browser worldwide, followed by Safari (popular on Apple devices), Microsoft Edge, and Firefox. Browser popularity varies by region and device type.
