User-Agent Parser

Pre-filled with your own browser's User-Agent — paste a different one to inspect it. Runs entirely in your browser.

ℹ️ About this parser

Uses pattern matching against known User-Agent formats — this is a best guess, not an authoritative parser. User-Agent strings have decades of quirks, and any client can send whatever string it wants (spoofing is trivial), so treat results as informative rather than a guarantee.
Windows report the same "NT 10.0" version string for both Windows 10 and 11 — the OS itself doesn't distinguish them in the User-Agent, hence "10/11".
Runs entirely client-side — nothing here is ever sent anywhere. The JSON API below is a separate, opt-in endpoint for scripts.
