User-Agent Parser

Parse a User-Agent string to identify the browser, operating system, device type, and rendering engine.

User-Agent String

Paste a User-Agent string above, or use your own browser's string, to see the parsed result.

User-Agent strings can be spoofed, so they should never be relied on for security decisions.

Most User-Agent strings still start with "Mozilla/5.0" for historical compatibility reasons.

All parsing runs locally in your browser; nothing is sent to external servers.
