What Cartie does

Cartie turns the cart — the last screen before checkout, and the one your theme gives you the least control over — into something you design. You build a cart out of widgets in a drag-and-drop builder, preview it exactly as shoppers will see it, and publish it to your storefront. No theme code, no developer.

#Where your Cartie cart appears

Once the Cartie block is enabled in your theme, Cartie renders in two places, and the same cart design is used for both:

#What you can put in a cart

Cartie ships 21 widgets. Some are display pieces (the product list, banners, trust badges, express wallet buttons); the rest exist to grow order value — free-shipping progress bars, upsell carousels, rewards ladders, volume discounts, countdown timers, subscribe-and-save, shipping protection, and more. See the widget reference for all of them.

#How a change reaches shoppers

1. 1
   You edit a cart in the builder

   Every change is saved automatically to a draft. Drafts are private — nothing your shoppers see changes yet.

2. 2
   You click Publish

   Cartie writes your cart's configuration to a global CDN and marks it as the live cart.

3. 3
   Storefronts pick it up

   Shoppers' browsers fetch that configuration file when the page loads. Updates usually appear within a minute; a hard refresh shows them sooner.

#How Cartie affects your store's speed

• The Cartie script is deferred — it runs after your page has painted, so it does not delay your Largest Contentful Paint.
• Your cart's configuration is a small static JSON file served from a CDN edge near the shopper, not a call to your store.
• On the /cart page Cartie reserves space for the cart before it renders, so the page does not jump as it loads.
