The quickest way for developers to find the user agent string in Chrome is through the built-in DevTools Console. This method works on all desktop platforms.
Press F12 or Ctrl+Shift+I (Mac: Cmd+Option+I )
If you're not comfortable with DevTools, Chrome has a built-in page that shows your full user agent string along with other version information.
Find the "User Agent" row — this is your full UA string
This method also works on Chrome for Android — simply type chrome://version in the mobile address bar.
Chrome's Network Conditions panel lets you view your current user agent and override it temporarily — useful for testing how websites respond to different browsers.
Click the ⋮ menu → More tools → Network conditions
Uncheck "Use browser default" to enter a custom string
For a quick popup display without navigating to DevTools, paste this in the Console or address bar:
Note: Chrome strips the javascript: prefix when pasting in the address bar. You'll need to type it manually, then paste the rest.
The easiest method for non-technical users — works on both desktop and mobile Chrome without any special steps.
A Chrome user agent string contains several key components. Here's how to read each part:
Google is moving Chrome away from the traditional UA string toward User-Agent Client Hints , a more structured and privacy-friendly API. To access it in Chrome DevTools:
Client Hints provide platform , mobile flag , and brand list by default, with high-entropy values available on request. This is Chrome's recommended approach for 2026 and beyond.
Open Chrome, press F12 or Ctrl+Shift+I (Cmd+Option+I on Mac) to open DevTools. Go to the Console tab and type navigator.userAgent, then press Enter. Your user agent string will be displayed immediately.
Yes. Open DevTools (F12), click the three-dot menu → More tools → Network conditions. Uncheck 'Use browser default' under User agent and select a preset or enter a custom string. This only affects the current tab and resets when DevTools closes.
A typical Chrome UA string looks like: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/131.0.0.0 Safari/537.36. It includes OS info, rendering engine, and Chrome version number.
Chrome includes 'Safari/537.36' in its user agent for historical compatibility reasons. Early websites checked for 'Safari' to serve WebKit-compatible content. Chrome, also WebKit-based (later Blink), kept this token to avoid being blocked by poorly written browser detection scripts.
In the user agent string, look for 'Chrome/' followed by the version number. For example, in 'Chrome/131.0.6778.86', the major version is 131. You can also type chrome://version in the address bar for detailed version info.
Yes. Google is gradually reducing information in Chrome's user agent string through the User-Agent Reduction plan. Minor version, build, and patch numbers are being replaced with '0.0.0'. The modern replacement is User-Agent Client Hints (navigator.userAgentData), which provides structured, privacy-preserving data.
On Chrome mobile (Android/iOS), type chrome://version in the address bar to see your full user agent. Alternatively, visit a tool like SnapWhatIsMy.com which displays your user agent instantly without requiring DevTools.
