Speculation Rules for PrestaShop

Make your PrestaShop store feel faster — before the customer even clicks.

Septsite Speculation Rules is a lightweight performance and UX module for PrestaShop that uses the browser’s native Speculation Rules API to prepare selected pages in advance.

Thanks to prefetch and prerender mechanisms, the browser can start loading likely next pages before the user clicks a link. The result is smoother navigation, shorter waiting time and a more modern shopping experience — without rebuilding your store or changing the server infrastructure.

What does the module do?

The module adds a configurable script[type="speculationrules"] to the storefront and allows you to define safe prefetch and prerender rules for selected links, such as categories, products or promotional pages.

It helps the browser predict where the customer may go next and prepare those pages in the background.

Key benefits

Faster navigation

Customers can move between pages more smoothly, especially when browsing categories and product pages.

Better user experience

The store feels more responsive and modern, similar to an application-like experience, while still working as a classic PrestaShop shop.

Less waiting

Likely next pages can be prepared in the background, reducing the perceived loading time after a click.

No server-side rebuild required

The module works on the frontend level using native browser capabilities. It does not require a full store redesign or backend architecture changes.

Safe exclusions

Sensitive pages such as checkout, customer account, cart or other dynamic areas can be excluded from speculation rules.

Ready-to-use rules

The module can be configured with conservative rules, making it easier to start safely and adjust settings later.

Who is it for?

Septsite Speculation Rules is designed for PrestaShop store owners who want to improve the browsing experience without complex development work.

It is especially useful for stores where customers browse many categories, products and promotional pages before making a purchase.

Why use Speculation Rules?

In e-commerce, speed is not only about technical scores. It is also about how fast the store feels to the customer.

A smoother browsing experience may help users stay longer, view more products and move through the store with less friction.
