User Agent Parser
See and decode any browser user-agent string.
See your own browser's user-agent string and decode any user agent into its parts — browser and version, operating system, rendering engine, and device type. Paste any UA string to parse it. Everything runs in your browser.
Parsed entirely in your browser — nothing is sent to a server. User-agent strings can be spoofed, so treat this as a best-effort guess.
Runs entirely in your browser — nothing is uploaded.

Frequently asked questions
What is a user agent?
A user-agent string is text your browser sends with every request, identifying the browser, version, operating system, and device.
What is my user agent?
It's shown at the top of this tool — your browser's exact user-agent string, parsed into browser, OS, engine, and device.
Can user agents be faked?
Yes — user-agent strings can be spoofed or changed, so treat parsed results as a best-effort guess.
Is my data sent anywhere?
No — parsing happens entirely in your browser; nothing is uploaded.
