Versus – Product Compare for WooCommerce

Versus adds a “Compare” button to your WooCommerce shop, archive and single product pages. Shoppers compare products side by side in a WooCommerce comparison table, with product data kept inside your store.

Versus is developed in the open. The code, and a place to report bugs or request features, live at github.com/wppoland/plogins-versus.

The table shows the product image, name, price, SKU, availability and short description, plus a row for every product attribute (colour, size, material and more). Rows whose values differ between products are highlighted, and a single toggle hides everything that is identical so the real differences stand out.

Built for speed and accessibility

• No jQuery in the plugin’s own front-end code, the script is vanilla JS, deferred and loaded in the footer.
• No layout shift (CLS). The comparison table scrolls horizontally inside its own wrapper, so adding columns never reflows the page.
• Keyboard friendly. The compare buttons are real buttons with aria-pressed state that updates over AJAX.
• Guests and customers. Logged-out visitors build and open a comparison stored per browser; logged-in customers get a “Compare” tab in My Account, and a guest list is merged into the account on login.

Settings

A WooCommerce-capability settings page (Versus menu) lets you:

• Enable or disable comparison and set how many products can be compared at once (2-6).
• Choose where the compare button appears (loops, single product), whether guests can use it, and an optional comparison page for guests.
• Choose which standard fields appear as rows (price, SKU, availability, short description) and whether to include product attributes.
• Toggle difference highlighting, the “differences only” default, and the image / add-to-cart / remove controls in each column header.
• Customise the front-end strings, the compare button, remove button, compare link, differences toggle, clear-all button and empty-list message, or leave them on their translated defaults.

Translation ready

All strings are translatable through the plogins-versus text domain, and a plogins-versus.pot template ships in /languages. Deleting the plugin removes its options and the comparison table.

How it works

Adding or removing a product is a single nonce-verified AJAX request; no full page reload. Guest selections are kept in a per-browser cookie for six months and merged into the account on login. The CSS and JavaScript are enqueued only on pages that actually show the compare button or the table.

Works with other Plogins plugins

• Shortlist – Wishlist for WooCommerce – with two or more products on the wishlist, a “Compare these” button opens them in the comparison table, up to your maximum products setting.

External Services

Versus does not connect to, or send any data to, any external service or third-party server. It bundles no SDK, API client, web font, map tile, CDN asset or analytics call, everything runs on your own site.

Comparison data stays inside your WordPress database: a custom {prefix}versus_compare_items table holds the compared product IDs, the plugin settings live in the versus_settings option (with versus_db_version tracking the schema), and a guest’s selection is kept in a first-party cookie in their own browser. Adding or removing a product is a same-origin AJAX request to your site’s own admin-ajax.php; no outbound HTTP request is ever made. Deleting the plugin removes those options and drops the table.

Translations

Versus is fully translatable and ships the plogins-versus.pot template. Translations are delivered by WordPress.org language packs from translate.wordpress.org, which is where Polish, German and Spanish are being contributed; the package itself carries no compiled translation files.
