Versus adds a Compare button to your WooCommerce shop loops and single product pages. Shoppers collect products into a list and Versus shows them in a side-by-side table with a row per field, highlighting the rows whose values differ. Logged-in customers reach their comparison under My Account > Compare; guests open it at a dedicated versus-compare endpoint.

Why stores pick Versus

The comparison table scrolls horizontally inside its own wrapper, so adding columns never reflows the page (no Cumulative Layout Shift). Adding or removing a product is a single nonce-verified AJAX request, no page reload, no jQuery. The free edition is the full GPL product: all comparison data stays in your own database, and Versus contacts no external service.

Free edition highlights

Compare button added automatically on shop and archive loops and on the single product page, each placement toggled independently.
Side-by-side table with a column per product (image, name, add-to-cart and remove controls in the header) and a row per enabled field.
Choosable rows, price, SKU, availability and short description, plus an optional row for each product attribute (colour, size, material).
Difference highlighting with a “show only differences” toggle that can default to on.
Guest and customer lists, guests get a per-browser list kept for six months; logged-in customers get a Compare tab in My Account, and a guest list merges into the account on login.
Per-list cap of 2-6 products, when a shopper exceeds it, the oldest item drops off automatically so the table never grows unreadably wide.
Editable front-end labels, compare button, remove button, compare link, differences toggle, clear-all button and empty-list message, with translated fallbacks.
Accessible, no-jQuery front end, aria-pressed buttons, a polite live region for screen-reader announcements, a live count badge on the compare link, and graceful handling of network failures and double clicks.

How comparison works

The compare button toggles a product on the shopper’s list over AJAX, updating its aria-pressed state and the count badge in place. Guests build a list stored in a versus_compare_session cookie; logged-in customers store it in the database against their user id, and a guest list is transferred to the account on login. The comparison table renders each product as a column and marks every row whose values differ, so shoppers focus on what actually separates the products.
