In this guide, we’ll compare the best Shopify cart drawer apps for 2025, including Instant, AMP, Upcart, and Kaching, so you can choose the right tool to optimize your store’s checkout flow and maximize revenue.

Best Shopify cart customization apps for 2025

1. Instant Section & Page Builder

Best for building your store and custom cart experience.

Instant goes beyond just cart customization: it’s a full Shopify theme builder that lets you design your entire store and create a completely custom cart drawer. You can add upsells, cross-sells, discount fields, progress bars, gift wrap, shipping add-ons, and announcement banners, all while keeping your cart perfectly on-brand. Unlike standalone cart apps, Instant lets you control the look and feel of your cart alongside your product pages, homepage, and more—so your customer journey feels seamless from start to checkout.

2. AMP – Slide Cart Drawer

Best for advanced cart upsells and promotions.

AMP helps brands increase average order value by turning the cart into a promotional hub. You can add upsell and cross-sell modules, show progress bars that unlock free gifts, and layer in discount codes directly within the cart. Features like sticky cart drawers and shipping protection upsells keep customers engaged and reduce abandonment. AMP is a solid option for stores that want conversion-focused features with lots of flexibility in promotion design.

3. Upcart – Cart Drawer Cart Upsell

Best for a seamless, on-brand cart design.

Upcart makes it easy to create a fully branded slide cart that feels like a natural extension of your store. Merchants can boost AOV with upselling and cross-selling blocks, highlight free shipping or discount thresholds, and even add extra services like shipping insurance. With sticky cart buttons and announcement options, Upcart helps reduce abandonment while keeping customers engaged inside a smooth cart experience.

4. Kaching AI Slide Cart Drawer

Best for simple, conversion-focused cart features.

Kaching is built for speed and simplicity, giving merchants an easy way to add urgency timers, free shipping bars, upsell toggles (like gift wrapping), and payment icons inside the cart. Its slide cart is designed with UX in mind, ensuring shoppers get a clear, engaging checkout experience without friction. If you want straightforward cart customization to increase conversions without heavy setup, Kaching is a strong choice.

Comparing the top Shopify cart drawer apps: 2025

Do cart drawer apps actually work and increase conversions?

Yes. Cart drawers (sometimes called slide carts or mini carts) are proven to help reduce abandonment and increase average order value (AOV). Unlike a traditional cart page, a drawer keeps shoppers in the buying flow. Instead of redirecting them away from the product page, it lets them see their selections instantly, with strategic upsells, add-ons, or discounts nudging them to spend more.

Some benefits merchants typically see include:

• Higher AOV: Progress bars, free gift incentives, and in-cart upsells motivate customers to add more.

• Reduced friction: Customers don’t have to leave the page they’re on, keeping the buying journey smooth.

• Lower abandonment: Sticky cart buttons and easy access reduce the chance of shoppers forgetting their cart.

• Better brand experience: On-brand designs ensure the cart feels integrated, not like a generic pop-up.

If you’re running paid traffic or trying to maximize conversion rates, a custom cart drawer is one of the highest-ROI Shopify features to test in 2025.

Shopify cart drawer vs cart page: which wins in 2025?

Both cart drawers and cart pages serve a purpose, but the drawer is increasingly the go-to choice for modern Shopify stores.

Cart drawers are best when:

• You want to keep customers shopping without redirecting them.

• You’re focused on upselling, cross-selling, or showing rewards progress.

• Mobile optimization is a priority (drawers work great on small screens).

Cart pages are best when:

• You sell higher-ticket or customizable items where customers need more details.

• You want to provide a more in-depth review before checkout.

• Your brand strategy includes content or storytelling at the cart stage.

Many high-growth stores use a hybrid approach: a cart drawer for most shoppers, with the option to expand to a full cart page if needed. Instant gives you the flexibility to do both.

Why Instant is the best choice for Shopify cart customization

While standalone cart apps focus only on the cart, Instant lets you design your entire store experience, plus a fully custom cart drawer. That means your cart isn’t an afterthought, but a seamless part of your brand journey.

With Instant, you get:

• Unlimited design control to match your store’s look & feel.

• Built-in upsells, rewards bars, and countdown timers.

• Strategic add-ons like shipping protection or gift wrapping.

• Trust-building elements like payment icons and badges.

• Performance insights through advanced cart analytics.

Instead of stitching together multiple apps, Instant gives you everything in one, making it easier to manage and ensuring a consistent experience for your customers.
