@cookieyes/nextjs@0.6.0
Self-hosted npm
This page shows CookieYes Next.js under the throttled-mobile profile, which applies a 4× CPU slowdown, 1,638 kbps down, 750 kbps up and 150 ms of added latency to simulate slower conditions; it does not emulate a phone screen. Every load is cold, and each figure is the p75 of 20 loads in the run of 24 Sep 2026. CookieYes Next.js scored 94/100 (Good) and ranked 1st of the 12 tested installations. The banner appeared in 264 ms (time to banner) and the page transferred 19.0 KB more than the no-SDK control (bytes over the wire). It delayed first paint by 43 ms (FCP) and added no Total Blocking Time (TBT), and the banner covered 11.7 % of the first viewport (viewport coverage).
