Understanding Browser Detection
Browser detection identifies your browser, version, and supported features using the navigator object and feature detection APIs. Unlike server-side user agent parsing, client-side detection is more accurate and respects user privacy.
Detection methods:
- User Agent parsing - Analyzes the UA string for browser name and version
- Feature detection - Checks for API availability (e.g.,
'serviceWorker' in navigator) - Capability tests - Tests actual functionality (e.g., WebGL context creation)
Why use browser detection? Modern web apps need to know if cutting-edge features like WebGPU, SharedArrayBuffer, or Web Bluetooth are available. Feature detection is better than version checking because browsers evolve differently.
This tool shows both metadata (browser, language, timezone) and capability flags to help you make informed decisions about what APIs your app can safely use.

Browser version is the marketing version (e.g., Chrome 120). Engine version refers to the rendering engine like Blink, WebKit, or Gecko. This tool shows the browser version, which is usually more useful for compatibility checks.
Do Not Track (DNT) is a deprecated privacy signal. Most modern browsers don't set it because it was never widely respected by websites. Browsers now use other privacy mechanisms like tracking protection.
While this tool shows browser capabilities, using it for fingerprinting is discouraged. Modern browsers actively fight fingerprinting by standardizing or hiding unique identifiers. Use feature detection for legitimate compatibility checks only.
If cookies are disabled, your browser blocks all website cookies. This breaks most session-based authentication. Third-party cookie blocking (common in privacy-focused browsers) shows as "Enabled" here.
Timezone detection via Intl.DateTimeFormat is very accurate and respects your system settings. It shows the IANA timezone name (e.g., "America/New_York"), which is more precise than UTC offsets.
💡 Tips
- Feature detection is better than browser version checking—test for the specific API you need (e.g., WebGL, WebRTC)
- SharedArrayBuffer requires cross-origin isolation headers; "No" here may indicate server config, not browser support
- Service Workers require HTTPS (except localhost); test on a secure connection for accurate results
- Language/timezone can reveal user location; be mindful of privacy when logging or fingerprinting this data
