As of Chrome 159, scheduled for general release on December 7, QWAC validation is turned on by default!
That means that in December, Chrome and Chromium users (AI agents included) will have a native way to validate QWACs, including 2-QWACs delivered in the HTTP header.
Google needed this to comply in advance with EU regulations requiring browsers to render QWACs by January 6, 2027. Our piece on the January 2027 EU rules has the background.
Exciting times!
