### What is Upcart—Cart Drawer Cart Upsell?

Upcart is a slide-cart app built around full design control, letting merchants build in-cart upsells, cross-sells, rewards and add-ons that match their storefront exactly, down to custom HTML, CSS and JSX. It carries the **Built for Shopify** badge and shows a 4.7/5 rating on 816 reviews, the lowest average rating among the cart-upsell apps in this batch. It's developed by Rokt (the same company behind Aftersell), based in Vancouver, and launched in July 2021.

### How does the app work on a Shopify store?

Merchants build a fully custom cart drawer with AI-powered in-cart upsells, a rewards progress bar toward free shipping, and add-ons like gift wrap, all editable through code-level HTML and CSS control rather than fixed templates. The cart stays visible via a sticky trigger across the store, aiming to reduce friction before checkout. It's currently English-only, and priced by monthly order volume tiers rather than by revenue share.

### Why choose Upcart over another cart upsell app?

Full HTML, CSS and JSX customization goes further than most competing cart-drawer apps in this list, which tend to offer a fixed set of style options rather than genuine code-level control, useful for a store with a very specific brand identity. Being part of the same company as Aftersell means a merchant could pair the two for a fuller upsell stack from one vendor across cart and post-purchase stages. The comparatively higher rate of 1-star reviews (5%) compared to Kaching CartDrawer or Kaching Bundles is worth digging into in hands-on testing, since a handful of reviews specifically mention frustration with AI-only support before reaching a human agent.

### What are the 3 main features of the app?

1. **Full code-level customization** of the cart drawer via HTML, CSS and JSX.
2. **AI-powered in-cart upsells and cross-sells**.
3. **Rewards progress bar** toward free shipping or gift thresholds.
