<p>¿What is <a href="https://developers.google.com/chrome/whitepapers/prerender" rel="nofollow ugc">Prerender</a> and <a href="http://en.wikipedia.org/wiki/Link_prefetching" rel="nofollow ugc">Prefetch</a>? Nice question. It’s a new-navigators technique (ok i’m a liar, Mozilla do it from 2003!) that loads in background the next page you believe the visitor is going to visit.</p>
<p>This plugin puts the required metatag in your WordPress pages, based on settings you can change, allowing those compatible navigators to do a pre-load of the next page. When the visitor try to visit that page Boom! it just appears without need to wait for it!</p>
<h4>Testing Prerender and Prefetch Support in your navigator</h4>
<p>You can <a href="http://prerender-test.appspot.com/" rel="nofollow ugc">test here Chrome’s prerender</a> with any page.</p>
<h4>Install and after install</h4>
<p>*When installing, remember to set the server’s load limit on settings.<br />
*This is a plugin in development, feel free to ask questions in “Support” section and colaborate with it.</p>


Prerender and Prefetch

Puts Prerender and Prefetch tag in the page. Allowing compatible navigators to do a pre-load of the page you figure the visitor is going to go.

WordPress.org

<p>This plugin adds support for the <a href="https://developer.mozilla.org/en-US/docs/Web/API/Speculation_Rules_API" rel="nofollow ugc">Speculation Rules API</a>, which allows defining rules by which certain URLs are dynamically prefetched or prerendered. This core Speculative Loading functionality was <a href="https://make.wordpress.org/core/2025/03/06/speculative-loading-in-6-8/" rel="nofollow ugc">merged into WordPress 6.8</a>, but it only prefetches with conservative eagerness by default. In contrast, this plugin defaults to prerendering with moderate eagerness (i.e. when interacting with a link), and it provides a user interface to customize the mode and eagerness via the “Speculative Loading” section on the <em>Settings > Reading</em> admin screen.</p>
<p>By default, speculative loading is only enabled for logged-out users, since unauthenticated pages are typically only eligible for caching and so more efficient to prefetch/prerender. This means that sites with frequent logged-in users on the frontend—such as e-commerce, forums, or membership sites—will not benefit from the feature. If your server can handle the additional load (for example, with persistent object caching), you can opt in to enable speculative loading for all logged-in users or for administrators only. This setting exclusively affects frontend pages; admin screens are always excluded.</p>
<p>A filter can be used to exclude certain URL paths from being eligible for prefetching and prerendering (see FAQ section). Alternatively, you can add the <code>no-prerender</code> CSS class to any link (<code><a></code> tag) that should not be prerendered. See FAQ for more information.</p>
<h4>Browser support</h4>
<p>The Speculation Rules API is a new web API, and the functionality used by the plugin is supported in Chromium-based browsers such as Chrome, Edge, or Opera using version 121 or above. Other browsers such as Safari and Firefox will ignore the functionality with no ill effects; they will simply not benefit from the speculative loading. Note that certain browser extensions may disable preloading by default.</p>

Speculative Loading

Nice


Amazing results on install. Will continue to check this one out. 


Interesting and Impressive

Does what it needs to do.

Enables browsers to speculatively prerender or prefetch pages to achieve near-instant loads based on user interaction.
