Features

Every capability, in detail

AI-built cart drawer

Addy reads your catalogue, theme and brand and assembles a complete cart drawer for you. You get a working, on-brand cart in minutes instead of an afternoon of configuration.

40+ drag-and-drop blocks

Upsells, bundles, progress bars, announcements, trust badges, order notes, discount fields, gift wrap, countdown timers and more — reorder any of them by dragging.

In-cart upsells and cross-sells

Show frequently bought together, related products or AI recommendations right where intent is highest, with one-click add and no page reload.

Volume discounts and free gifts

Buy-more-save-more tiers, BOGO, bulk pricing, automatic discounts and free gift thresholds, all resolved natively at checkout.

Reward progress bars

Stack goals for free shipping, order discounts and free gifts so shoppers always have a reason to add one more item.

Market and segment targeting

Build a different cart for every Market or customer tag, and add conditions to individual blocks so the right offer reaches the right shopper.

Estimated delivery dates

Show a real delivery window inside the cart to remove the biggest pre-checkout unknown and reduce abandonment.

Custom HTML and CSS

Drop in your own markup and styles when a design needs to go beyond the settings panel. No theme edits, no developer required.

FAQ

Questions merchants ask

Does Addy work with my Shopify theme?

Yes. Addy installs as a theme app extension and is compatible with every Online Store 2.0 theme, plus page builders such as PageFly, GemPages, Foxify and EComposer. There are no theme file edits, so uninstalling leaves nothing behind.

Will the cart drawer slow my store down?

Addy loads asynchronously and only renders when the cart is opened, so it stays out of the critical rendering path. It does not block your Largest Contentful Paint and adds no render-blocking scripts.

Can I show different carts in different countries?

Yes. Addy supports Shopify Markets targeting, so you can run a different cart layout, different offers and different free shipping thresholds per Market, and target individual blocks by customer tag as well.

How much does Addy cost?

Addy is free to install from the Shopify App Store.

Does Addy support multiple languages and currencies?

Yes. Every string is translatable and prices render in the shopper’s presentment currency, so international carts read correctly without extra configuration.
