Labelix replaces the default Add to Cart button with a custom label, color, emoji icon, and border radius. Create reusable button styles – called Configs – and apply them with Rules to specific products, collections, or your entire store. Rules activate based on stock level – show Pre-Order when out of stock, or a scarcity message when inventory runs low. Every config supports per-language translations, so each visitor sees the button in their own language automatically.
