User Agent Info

Explore detailed information about your browser’s user agent with our User Agent Info tool. Understand what browser and operating system you’re using, along with additional details such as JavaScript and cookies status, screen size, and more.

What is a User Agent?

A user agent is a string of text that your web browser sends to every website you visit. This string identifies your browser, operating system, device type, and various capabilities. Websites use this information to deliver content optimized for your specific setup, ensuring compatibility and the best possible user experience. Our User Agent Info tool displays all the information your browser reveals when you visit websites.

Why User Agent Information Matters

User agent information serves several important purposes in modern web browsing:

Website Compatibility

• Browser detection: Websites check your user agent to determine which browser you’re using and serve compatible code (HTML, CSS, JavaScript) accordingly.
• Feature detection: Sites identify which modern web features your browser supports (like WebGL, WebSockets, or HTML5 video) and adjust content delivery.
• Mobile optimization: Websites detect mobile devices through user agents and deliver mobile-optimized layouts and touch-friendly interfaces.
• Legacy support: Older browsers get alternative versions of websites that work with their limited capabilities.

Analytics and Statistics

• Traffic analysis: Website owners track which browsers, devices, and operating systems their visitors use to guide development priorities.
• Usage trends: Organizations monitor user agent data to understand technology adoption rates and plan feature support.
• Regional patterns: Combined with location data, user agents help identify regional browser preferences and device usage patterns.
• Performance optimization: Developers use user agent statistics to optimize performance for the most common configurations.

Security and Bot Detection

• Bot identification: Websites distinguish between human visitors and automated bots, search engine crawlers, or scrapers based on user agent patterns.
• Security monitoring: Unusual user agent strings can indicate malicious activity or automated attacks.
• Access control: Some services restrict or grant access based on user agents, blocking outdated browsers or suspicious patterns.

Common Uses for User Agent Information

For Developers and Testers

• Browser testing: Verify that websites display correctly across different browsers and versions.
• Bug reporting: Include user agent details when reporting browser-specific issues to help developers reproduce problems.
• Feature detection: Check whether specific web technologies are supported before implementing them.
• Responsive design testing: Test how websites adapt to different screen sizes and device types.

For Technical Support

• Troubleshooting: Provide technical support teams with detailed browser information when seeking help.
• Compatibility verification: Confirm that your browser meets minimum requirements for web applications or services.
• Update checks: Identify outdated browser versions that may need updating for security or compatibility.

For Privacy-Conscious Users

• Fingerprinting awareness: Understand what information websites can collect about your browsing environment.
• Privacy assessment: See what makes your browser unique and potentially trackable across websites.
• Tracking protection: Verify that privacy extensions or settings are working as intended.

Understanding User Agent Privacy

While user agent information helps websites function properly, it also raises privacy considerations:

• Browser fingerprinting: The combination of user agent details, screen size, installed plugins, and other factors creates a unique "fingerprint" that can track you across websites even without cookies.
• User Agent Reduction: Modern browsers are gradually reducing the information shared in user agent strings to enhance privacy while maintaining compatibility.
• Privacy extensions: Some browser extensions modify or randomize user agent information to prevent tracking.
• Incognito limitations: Even in private browsing mode, your user agent information is still transmitted to websites.
