About the My User Agent

This page shows your user agent string and the browser, version, operating system and device type it reports. It is the fastest way to answer "which browser and version are you on?" in a bug report.

Your user agent is the identification string your browser sends with every request. It is how a server can tell a mobile Safari request from a desktop Chrome one, and it is the first thing anyone triaging a bug report asks for.

The strings themselves are a mess of historical accident. Almost every browser still claims to be Mozilla and includes tokens like AppleWebKit and KHTML that it has no real relationship with, because sites once sniffed for those names and browsers copied them to avoid being locked out.

Because of that, user agent sniffing is unreliable and browsers are actively reducing what they disclose. Feature detection is the right approach in code — check whether the capability exists rather than guessing from a name. To parse a string other than your own, use the user agent parser.

How to use the My User Agent

  1. Open the page. Your user agent string is read from your browser.
  2. Read the parsed details. See the browser, version, operating system and device type.
  3. Copy the raw string. Take it for a bug report or support ticket.
  4. Parse another string. Use the user agent parser for a string you have been given.

Frequently asked questions

How does user agent parsing work?

Our parser analyzes user agent strings using pattern matching and regular expressions. Extracts browser name and version, operating system and version, device type, rendering engine, and other identifiable characteristics from the UA string.

What browsers and devices are supported?

Comprehensive support for: Chrome, Firefox, Safari, Edge, Opera, Internet Explorer, Samsung Browser, Chromium, mobile browsers, desktop browsers, tablets, and various device types with version detection and OS identification.

What information can be extracted from user agents?

Detailed extraction includes: browser name and version, operating system and version, device type (desktop/mobile/tablet), rendering engine (WebKit, Gecko, Blink), and identifiable characteristics for analytics and compatibility analysis.

What are the applications of user agent analysis?

Essential for: browser compatibility testing, analytics and tracking, device-specific optimizations, feature detection, security analysis, content adaptation, and understanding user demographics for web development.

How can this help with web development?

Critical for development: responsive design testing, browser-specific CSS, feature compatibility checks, progressive enhancement, analytics integration, and ensuring consistent user experience across different browsers and devices.

What are the limitations of user agent parsing?

Considerations: user agents can be spoofed, new browsers may not be recognized, mobile detection can be complex, and some privacy-focused browsers limit identifiable information. Use as guidance rather than absolute detection.

Is this suitable for professional analytics and development?

Absolutely! Professional-grade parsing suitable for web developers, analytics specialists, and UX designers. Perfect for compatibility testing, user experience optimization, and data-driven development decisions.
