The Product Comparison module adds a complete, professional side-by-side comparator to your PrestaShop store. "Compare" buttons appear automatically on the product page and in listings, and a dedicated page lines up the selected products in columns for an informed purchase decision.

The comparison page freezes the header and first column, highlights the best price with a dedicated badge and offers a "show differences only" toggle that hides identical rows. A floating bar follows the shopper across the whole store, and every comparison generates a shareable URL. 100% self-contained, vanilla JavaScript, with no dependency whatsoever.
