About

The rel="prefetch" attribute on HTML <link> elements tells the browser to download resources that are likely to be needed for future navigation when the current page is idle.

It allows caching resources in advance with low priority and is commonly used for next-page documents, scripts, styles, or assets in multi-step flows.

The Speculation Rules API is a browser API that improves navigation performance by prefetching or prerendering pages that users are likely to visit next.

It uses JSON-based rules embedded in HTML or HTTP headers, and is designed as a successor to older techniques such as Prefetch and the deprecated Prerender attribute.
