Spectrum Customizer embeds product customization directly into Shopify storefronts. Customers personalize products (colors, materials, prints) in an overlay modal without leaving the store, then add to cart with a live preview image. The setup is zero-code, addons/upcharges resolve automatically, designs save & resume, and it works beautifully on mobile. One app connects their Spectrum account to all their Shopify stores.
