Selling the same product in multiple colors or sizes as separate listings splits your catalog and makes shoppers work harder to find what they want. VariantX links related products into one combined listing, so customers switch colors, sizes, and materials from a single product page. Merchants build groups, add color, image, or text swatches, and apply ready-made templates that match their theme. An automation scanner detects groups from product titles, tags, and metafields in seconds.
