VarHide automatically hides sold out variants so shoppers only see options they can actually buy. When inventory changes, out-of-stock variants are unpublished from your online store, B2B catalogs, Shopify Markets, and any sales channel you choose — then republished the moment stock returns. Because variants are hidden at the sales-channel level, they disappear from product pages, search, and collection filters with no theme code and no flicker. Set your own rules with the query builder.
