Cloudflare has introduced Speed Brain, a new feature designed to reduce page load latency by predicting how visitors will interact with a given web page. The technology relies on the Speculation Rules API to prefetch content of likely next navigations and aims to download a web page to the browser cache before a user navigates to it, allowing pages to load almost instantly when actual navigation takes place. Speed Brain is currently available for all plan types at no cost and can be toggled on from the dashboard or API.
