What is My Browser
Detect your browser information
What Is My Browser? See Your Full Browser Details
What is my browser is an instant detection tool that reveals your browser name, version number, operating system, rendering engine, and user agent string the moment you open the page — no sign-up, no extensions, and no manual digging through settings menus required.
Benefits of the browser detection tool
- Instantly see your exact browser name and version without opening any settings panel.
- Learn which operating system and CPU architecture your browser is running on (Windows, macOS, Linux, Android, iOS).
- Identify the rendering engine (Blink, Gecko, or WebKit) — essential when debugging layout inconsistencies across browsers.
- Confirm whether your browser has JavaScript enabled, cookies active, and modern web APIs available.
- Quickly match your browser environment against the minimum requirements of any web application or SaaS tool.
Use cases for the browser info checker
- Web developers can ask users to visit this page and share a screenshot instead of walking through multiple settings steps to find browser info.
- Help-desk and support teams include this link in first-response emails to gather client environment details before investigating bugs.
- Everyday users can verify whether their browser is up to date and whether it meets security recommendations.
- QA testers confirm the exact browser environment on a real device before executing cross-browser test cases.
- Detect whether a link was opened inside a social media in-app browser (such as Facebook or Instagram) rather than the device's native browser.
- Diagnose display issues caused by an outdated or unsupported browser version before escalating to development.
How to use the browser detection tool
- Open the page — browser information is detected and displayed automatically, with no button to press.
- Review the results: browser name, version, OS, rendering engine, screen resolution, and the full user agent string.
- Use the Copy button or take a screenshot to share the details with a developer or support agent.
- Compare your browser version against the recommended or minimum version listed by the service you are trying to use.
Frequently asked questions
Does this tool collect or store any of my data? No. All information is read directly from your browser's built-in APIs and displayed only on your screen — nothing is transmitted to or stored on any server.
Why does the browser version matter? Outdated browsers may lack support for modern security protocols, CSS features, and JavaScript APIs, leading to broken layouts or security vulnerabilities on up-to-date websites.
Does it work on mobile devices? Yes. The tool works on any device — desktop, Android, iPhone, or tablet — and the result accurately reflects that specific device's browser environment.
What is a user agent string? It is a text string your browser sends to every web server identifying itself, including the browser name, version, OS, and engine. This tool displays the full raw string so you can copy it for debugging or support tickets.
