Every time a customer clicks "Add to Cart" and gets redirected to a separate cart page, you lose momentum. They see the total, reconsider, and leave. The best Shopify slide cart apps fix this by opening a cart drawer on the side of the page without navigating away — keeping shoppers in buying mode. Stores using optimized cart drawers see 5–12% higher conversion rates compared to traditional cart pages, and free shipping progress bars alone add 8–12% to average order value.
If you're still sending customers to /cart, you're creating a decision point where none needs to exist. A slide cart keeps the shopping flow unbroken and gives you space to show upsells, reward thresholds, and trust signals right where the buying intent is highest.
What Should a Slide Cart App Include?
A good slide cart app needs five things: in-cart upsells, progress bars, strong mobile performance, visual customization, and fast load times. Here's what each means in practice:
- In-cart upsells and cross-sells — product recommendations inside the drawer, not just a list of what's already in the cart
- Progress bars — free shipping thresholds, discount tiers, or free gift milestones that nudge customers to add one more item
- Mobile performance — most Shopify traffic is mobile, and a slow or cramped cart drawer does more harm than a basic cart page
- Customization without code — colors, layout, and modules you can adjust from the app dashboard
- No speed penalty — the app should load asynchronously and not bloat your Core Web Vitals
Every app below has a free plan or free trial, so you can test before committing.
1. Kaching CartDrawer Cart Upsell
Rating: 5.0 stars (838 reviews) · Built for Shopify · From $9.99/month
Kaching has the highest review count of any 5.0-rated slide cart app on the Shopify App Store. The feature set is focused: a customizable slide cart with upsell toggles (think shipping protection or gift wrap), a free shipping bar, urgency timers, and payment icons. It supports 7 languages out of the box.
Where Kaching stands out is simplicity. No bloated dashboard, no 40-tab setup wizard. You install it, pick your modules, style the cart, and you're live. For stores that want a clean cart drawer without spending an afternoon configuring it, this is the pick.
Best for: Merchants who want a fast, no-fuss slide cart that just works.
2. Amp Slide Cart Upsell Drawer
Rating: 5.0 stars (653 reviews) · Built for Shopify · From $24.99/month (free for 0–50 orders)
Amp goes deeper on the upsell side. You get cross-sell recommendations, BOGO offers, frequently bought together bundles, and free gift promotions — all inside the cart drawer. It also supports discount code entry directly in the cart, which removes a friction point that causes some shoppers to leave and search for coupons.
The multi-currency and multi-language support makes it a strong choice for international stores. Custom HTML/CSS is available if you need precise branding control beyond the drag-and-drop editor.
Best for: Stores running promotions and bundles that need advanced upsell logic inside the cart.
3. iCart Cart Drawer Cart Upsell
Rating: 4.7 stars (433 reviews) · Built for Shopify · From $9/month (free for 0–100 lifetime orders)
iCart is one of the most established cart drawer apps on Shopify. Its editor lets you build both a slide cart and a full cart page, so you're not locked into one format. Features include multi-tier progress bars (stack free shipping + free gift thresholds), AI-powered product recommendations, volume discounts, and countdown timers.
The free tier covers your first 100 lifetime orders — generous enough to test the app's impact on real conversions before you pay anything. 90% of iCart's reviews are 5-star, with merchants consistently praising the support team's responsiveness.
Best for: Growing stores that want both a cart drawer and cart page in one app, with AI recommendations.
4. Upcart — Cart Drawer Cart Upsell
Rating: 4.6 stars (745 reviews) · Built for Shopify · From $29.99/month
Upcart's differentiator is customization depth. You can build fully branded cart templates using HTML, CSS, and JSX — which is unusual for a Shopify app. The reward bar is well-designed: set multiple tiers (spend $50 for free shipping, $75 for a free gift) and the progress bar updates in real time as customers add items.
The downside: no free plan for live stores (only development stores), and pricing starts at $29.99/month, which is higher than Kaching or iCart. But if brand consistency is a priority and you have the budget, Upcart gives you more design control than most competitors.
Best for: Brand-conscious stores that want pixel-perfect cart design and are comfortable editing code.
5. Oxify Cart Drawer Cart Upsell
Rating: 5.0 stars (34 reviews) · Built for Shopify · From $19.99/month
Oxify is newer to the market but packs the widest feature set in this list. Beyond standard cart drawer features, it includes post-purchase upsell funnels, product page upsells, subscription management inside the cart, and BOGO mechanics. It also claims a 30-day ROI guarantee — if you don't see a return, you don't pay.
The low review count (34) is the main concern. The app hasn't been battle-tested at the scale of Kaching or Amp. But the feature density and 5.0 rating suggest it's worth watching, especially if you want upsells that extend beyond just the cart drawer.
Best for: Stores looking for an all-in-one upsell system (cart + product page + post-purchase) rather than just a cart drawer.
6. Sticky Cart by Kaktus
Rating: 4.6 stars (148 reviews) · Built for Shopify · Free plan available
Kaktus offers the only truly free slide cart app in this list. The free tier has no order limits — you get a functional cart drawer with custom styling, cart notes, and basic features at zero cost. Paid plans ($29.99/month) add upsell recommendations, frequently bought together, free shipping bars, and countdown timers.
The free plan is solid for stores just getting started or testing whether a slide cart improves their metrics before investing in a premium option. Some merchants in reviews mention occasional checkout conflicts, so test it with your theme before going live.
Best for: New or budget-conscious stores that want a free slide cart to start.

How to Pick the Right Slide Cart App
Skip the feature comparison paralysis. Answer these three questions:
- What's your budget? If zero, start with Kaktus. If under $15/month, Kaching or iCart. If you need the full upsell toolkit, Amp or Oxify.
- How important is brand consistency? If your slide cart needs to match your design system exactly, Upcart's code-level customization is hard to beat. If "close enough" works, any of the other five will do.
- Do you need upsells beyond the cart? Most of these apps focus on the cart drawer. Oxify extends to product pages and post-purchase. If you want one app handling upsells everywhere, that matters.
Install your top pick, run it for two weeks, and compare your AOV before and after. Every app on this list has a trial period — use it. The numbers will tell you more than any feature comparison.
If your store runs on COD order forms rather than the standard Shopify cart, a slide cart app won't help — you need upsells built into the order form itself. EasySell handles that with quantity discounts, add-ons, and cross-sells directly inside the COD order form.
