Side-by-side comparison

The lowest-priced column is highlighted with a dedicated badge to guide the buying decision at a glance.

03

Differences in one click

A "show differences only" toggle hides identical rows to surface only what truly sets the products apart.

Floating bar and shareable link

A selection bar with thumbnails follows the shopper across the whole store, and every comparison generates a shareable URL.

The long version

Everything you'd want to know before you install.

A detailed look at how Product Comparison Module for PrestaShop 8/9 works, why we built it the way we did, and the thinking behind the features above.

§ 01

The comparison that truly helps decide

The customer adds the products they are interested in to their comparison from the product page or directly in listings, then opens a dedicated page that lines them up in columns. The header and first column stay frozen while scrolling so the context is never lost, even with a long feature table.

§ 02

Best price and differences brought forward

The lowest-priced column is automatically highlighted with a dedicated badge. A "show differences only" toggle hides rows whose values are identical across all products, leaving only what truly distinguishes the items and speeding up the decision.

§ 03

Present everywhere, without disrupting the journey

The "Compare" buttons are added automatically on the product page and in listings, and re-injected after every Ajax filtering. A floating bar with thumbnails accompanies the shopper across the whole store, and each comparison produces a shareable URL to send or find again.

§ 04

Built for PrestaShop 8 and 9

No-Composer, no-framework architecture, manual PSR-4 autoloader and a classic front controller for seamless PrestaShop 8 and 9 compatibility, single store or multistore, across the catalogue's five languages.

§ 05

Fast, self-contained and theme-friendly

The comparator is written in vanilla JavaScript, with no jQuery or external dependency. The selection is kept by browser token with a localStorage mirror for instant rendering, and merged across devices for logged-in customers. The design is self-contained, independent from your theme and responsive.
