The slide cart your
storefront deserves
AI cross-sells, free-shipping bar, bundles, BOGO, gift wrap and shipping protection — all in one drawer that loads in <100ms.
10 blocks. One
branded checkout.
Banners, rewards bar, free gift, shipping protection, smart recs, order notes, terms, payment icons, branding & social proof — drop in what you need.
One platform. Every conversion surface.
Most apps optimize one moment. Cartylabs gives you a unified stack from the cart drawer all the way through checkout — with shared analytics and a single bill.
One AI engine
The same recommendation model powers cart upsells and checkout cross-sells — so offers stay coherent across the funnel.
Unified analytics
Track AOV lift, attach rate and ROI for every offer — across cart, checkout and post-purchase — from one dashboard.
Built for Shopify
Native Shopify checkout extensibility, theme app blocks, and Plus-ready features — no custom dev required.

"Branding our checkout was the missing piece. The rewards bar at checkout reduced abandonment dramatically."
"Replaced three separate apps with Cartylabs. One bill, one dashboard, no more conflicts."
Common questions
More in our help center — or talk to us if you have a specific use case in mind.
What is the difference between the Cart and Checkout apps?
The Cart Drawer app lives on the storefront and lifts AOV before checkout — slide-out cart, upsells, free shipping bar, bundles. The Checkout Customizer runs inside Shopify checkout itself: branding, upsells, rewards bar, banners, trust badges. Use them together for an end-to-end conversion stack.
Do I need both apps?
No. Each app is designed to stand alone — install only what you need. Many merchants start with the Cart Drawer (free), then layer in the Checkout Customizer once they want to optimize the checkout step itself.
Does the Checkout Customizer work without Shopify Plus?
Yes. Core branding, upsells, banners and the rewards bar work on every Shopify plan. A few advanced extensions (unlimited branding profiles, custom checkout extensions) are reserved for Shopify Plus.
How fast can I get set up?
Most merchants are live in under 10 minutes. Both apps install from the Shopify App Store, autodetect your theme, and ship with sensible defaults you can tweak in a no-code editor.
