This plugin adds support for the <a href="https://developer.mozilla.org/en-US/docs/Web/API/Speculation_Rules_API">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/">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.
