User Agent Parser
Decode any user agent string into browser, OS, engine and device.
About the User Agent Parser
Every request your browser makes carries a user agent string. Paste one here — your own is filled in automatically — and see the browser and version, operating system, rendering engine, device type and whether it belongs to a bot.
Handy when reading server logs, debugging a device-specific bug, or checking what a crawler is reporting.
Frequently asked questions
Why do all user agents mention Mozilla?
A compatibility hangover from the 1990s browser wars. Nearly every browser still starts its string with Mozilla/5.0 so that old servers do not refuse it.
