Quicklink for WordPress attempts to make navigation to subsequent pages load faster. Embedded with the plugin is a javascript library, which detects links in the viewport, waits until the browser is idle and prefetches the URLs for these links. The library also tries to detect, if the user is on a slow connection or on a data plan.
This plugin builds heavily on the amazing work done by <a href="https://github.com/GoogleChromeLabs/quicklink" rel="nofollow ugc">Google Chrome Labs</a>.

<h4>How it works</h4>
<ul>
<li>Detects links within the viewport (using <a href="https://developer.mozilla.org/en-US/docs/Web/API/Intersection_Observer_API" rel="nofollow ugc">Intersection Observer</a>)</li>
<li>Waits until the browser is idle (using <a href="https://developer.mozilla.org/en-US/docs/Web/API/Window/requestIdleCallback" rel="nofollow ugc">requestIdleCallback</a>)</li>
<li>Checks if the user isn’t on a slow connection (using <code>navigator.connection.effectiveType</code>) or has data-saver enabled (using <code>navigator.connection.saveData</code>)</li>
<li>Prefetches URLs to the links (using <a href="https://www.w3.org/TR/resource-hints/#prefetch" rel="nofollow ugc"><code><link rel=prefetch></code></a> or XHR). Provides some control over the request priority (can switch to <code>fetch()</code> if supported).</li>
</ul>

Quicklink for WordPress

Thanks for publishing this. Works really well. Would be nice to see option to loading Quicklink from a CDN.

Great plugin

⚡️ Faster subsequent page-loads by prefetching in-viewport links during idle time.

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 Settings > Reading admin screen.
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.
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.
<h4>Browser support</h4>
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.

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.
