User-Agent Client Hints
Client Hints are the structured replacement for the User-Agent string on Chromium browsers. The low-entropy set is sent on every request; the high-entropy values are revealed only when a site asks. Here is everything your browser will disclose.
Low-entropy hints · sent automatically
High-entropy hints · disclosed on request
Only Chromium sends these
Chrome, Edge, Opera, Samsung Internet, Brave and other Chromium browsers implement Client Hints. Firefox and Safari have declined to, so on those browsers this page shows nothing — which is itself a signal. A request that claims to be Chrome but carries no Sec-CH-UA headers is contradicting itself. For a full User-Agent breakdown, see our sister tool useragent.in ↗.
