rel=prerender

Deprecated: This feature is no longer recommended. Though some browsers might still support it, it may have already been removed from the relevant web standards, may be in the process of being dropped, or may only be kept for compatibility purposes. Avoid using it, and update existing code if possible; see the compatibility table at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.

Non-standard: This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

The prerender keyword for the rel attribute of the <link> element is a hint to browsers that the user might need the target resource for the next navigation, and therefore the browser can likely improve the user experience by preemptively fetching and processing the resource — for example, by fetching its subresources or performing some rendering in the background offscreen.

This feature is superceded by the Speculation Rules API.
