Detect your browser name, version, rendering engine, user agent string and supported features — all detected locally in your browser, nothing sent to our servers.
A user agent is a string of text that your browser sends with every web request, identifying the browser, its version, the operating system, and the rendering engine. Web servers use this information to serve optimised content for your specific browser and device.
The user agent string typically includes the browser name and version, the operating system name and version, and the rendering engine (Blink, Gecko, or WebKit). For example, a Chrome user agent might look like: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/126.0.0.0 Safari/537.36
Keeping your browser updated is one of the most important steps you can take for online security. Browser updates fix security vulnerabilities that could be exploited by malicious websites, add support for new web standards, improve performance and stability, and often include enhanced privacy features.
Major browsers release security updates frequently — Chrome and Edge update approximately every 4 weeks, Firefox every 4 weeks, and Safari updates are tied to macOS and iOS releases.
