# Cart Rocket > Cart Rocket is a Shopify app that creates pre-loaded cart links (rocket links): one shareable URL that adds specific products and variants to a customer's cart, applies discounts automatically, and sends them to the cart page, checkout, or Shop Pay. Built for merchants running paid ads, email, SMS, and creator campaigns. Cart Rocket requires no theme code and works with all Shopify themes, including Dawn. Presets can include line-item, cart-wide, and shipping discounts plus auto-applied Shopify discount codes; bundles; customer eligibility rules; purchase limits; UTC scheduling; UTM and custom tracking; Tag order (add campaign-style tags to Shopify orders from a link — existing order tags preserved; not customer tags); optional conversion notes; QR codes; Shopify Flow automation guides; and Shopify Sidekick tools. Every cart modification is signed server-side.
