Speculative Loading

Speculative Loading is a WordPress plugin that implements resource hints and prefetching strategies to improve perceived page load performance. It uses browser APIs like prefetch, preconnect, dns-prefetch, and prerender to load resources before they are explicitly requested by users. The plugin automatically analyzes internal links and prefetches pages that users are likely to navigate to next, making subsequent page loads appear instantaneous. It implements intelligent strategies to prefetch resources during idle time without interfering with current page performance. Speculative Loading supports customization of which pages and resources should be prefetched based on likelihood and priority. The plugin leverages the Speculation Rules API in modern browsers for more sophisticated prefetching capabilities. It is particularly effective for content-heavy sites, blogs, and documentation sites where users frequently navigate between related pages.
