Instant.Page

Instant.Page is a lightweight JavaScript library that dramatically improves perceived website performance by preloading pages before users click on links. The library uses just-in-time preloading, fetching pages when users hover over links or touch them on mobile devices. This approach reduces the delay between clicking and page display, creating an instant browsing experience. Instant.Page intelligently determines which links to preload based on user behavior and hover duration. It includes safeguards to prevent excessive preloading that could waste bandwidth or overload servers. The library is extremely small (under 1KB) and has no dependencies, making it trivial to add to any website. Instant.Page works automatically with no configuration required, though it offers options for customization. It's particularly effective for content-heavy websites where navigation speed significantly impacts user experience and engagement.
