Introducing Speed Brain: helping web pages load 45% faster

Speed Brain, a new feature from Cloudflare, aims to significantly reduce web page load times by prefetching content before users click. It uses the Speculation Rules API to download pages into browser cache in advance, potentially reducing Largest Contentful Paint (LCP) by up to 75%. Speed Brain is available for free to all Cloudflare customers and has already shown a 45% reduction in LCP on free domains. The feature works by predicting user behavior and prefetching static, cacheable content, with built-in safeguards to prevent incorrect prefetching and stale configurations.
