Amp Slide Cart vs Cartylabs: Feature-by-Feature Breakdown

Amp (useamp.com) and Cartylabs both show up early in any 2026 Shopify cart drawer search. Amp is a four-app suite — Slide Cart, Bundles, Back in Stock, Post Purchase — built around the idea of consolidating a four-vendor stack under one bill. Cartylabs is an all-in-one cart embed: drawer, AI upsells, rewards, sticky cart, countdowns, and analytics in a single install.

They’re solving the same merchant pain (too many apps doing too little each) from two different angles. This breakdown covers the feature-level differences, where each one wins, and which type of store should pick which.

Quick answer#

• You want one cart embed that does everything pre-checkout (drawer + upsells + rewards + countdowns): Cartylabs.
• You also need bundles, back-in-stock, and post-purchase from a single vendor: Amp’s four-app suite.
• You only need a cart drawer and nothing else: Amp Slide Cart standalone is solid (91k+ installs, 5.0 rating).
• You need deep AI recommendations and stacked rewards tiers: Cartylabs.

If you’re comparing single apps, Cartylabs and Amp Slide Cart are close on the basics and diverge on AI logic, rewards depth, and analytics. If you’re comparing whole stacks, Amp wins on breadth and Cartylabs wins on depth-per-feature.

What each product is#

Amp Slide Cart is the cart drawer in Amp’s four-app suite. It’s a solid, well-rated drawer with the standard feature set: line items, qty controls, free-shipping bar, basic upsell carousel, and theme matching. The strategic context is that Amp also sells Bundles, Back in Stock, and Post Purchase as separate apps that integrate with the slide cart.

Cartylabs is a single Shopify App Embed that bundles cart drawer + sticky cart + AI product recommendations + free-gift progress bar + countdown + shipping protection + analytics. Setup runs about 2-5 minutes; there’s no theme code or JavaScript snippet. The strategic context is that Cartylabs collapses a four-app pre-checkout stack into one install.

Pricing comparison#

Both publish entry tiers around the same price; the math diverges as you add more apps or scale order volume.

Product	Entry price	Apps included	Suite total at scale
Cartylabs	Free plan, then flat tiers	All pre-checkout features in one	Single bill
Amp Slide Cart	$19.99/mo	Slide cart only	Add Bundles ($), Back in Stock ($), Post Purchase ($)

If you only need a cart drawer, Amp Slide Cart and Cartylabs are roughly the same monthly cost. If you need three or four pre-checkout features, Cartylabs is meaningfully cheaper because the features ship together. If you also need bundles, back-in-stock, and post-purchase, Amp’s suite math becomes competitive again.

The headline: Cartylabs goes deeper on each pre-checkout feature; Amp covers more surfaces but as separate apps you have to install and configure individually.

Where Cartylabs wins#

Three areas where the difference is real, not marketing.

1. AI recommendations. Cartylabs trains a per-store recommendation model on real shopper sessions. Amp’s slide cart uses simpler logic (“frequently bought together,” manual rules). For catalogs above ~50 SKUs, the per-store ML measurably outperforms global rules. See AI product recommendations on Shopify for why this matters.

2. Stacked rewards tiers. Cartylabs supports multi-tier reward bars: “$50 free shipping → $100 free gift → $150 10% off.” Amp’s slide cart does single-tier. For stores that lean on rewards as a primary AOV lever, this is significant. See free-gift progress bar guide.

3. One-embed setup. Cartylabs ships drawer, sticky cart, rewards, AI upsells, countdowns, and shipping protection in a single App Embed toggle. Amp requires installing each app separately and configuring inter-app integrations. For a non-technical merchant, the time difference is meaningful.

Where Amp wins#

Equally honest:

1. Suite consolidation. If you genuinely need bundles + back-in-stock + post-purchase + cart drawer, Amp under one vendor is operationally cleaner than Cartylabs + Klaviyo Back-in-Stock + AfterSell. One bill, one support team, one set of analytics conventions.

2. Bundles depth. Amp Bundles (the separate app) has more sophisticated bundle pricing UI than Cartylabs’ rewards-bar approach to bundle mechanics. If your merchandising story is heavily bundle-driven (kits, stacks, routines), Amp Bundles is purpose-built for that.

3. Track record on Slide Cart specifically. 91k+ installs and a 5.0 rating reflect real merchant satisfaction with the drawer itself. Cartylabs is newer; the install base is smaller, even if the feature set is broader.

4. Back-in-stock notifications. Amp ships a back-in-stock app; Cartylabs doesn’t have that on the roadmap as of 2026.

Setup experience#

Cartylabs setup: Install from Shopify App Store → enable App Embed → pick a theme preset → set rewards thresholds → save. Realistic time: 2-5 minutes. Live with all features on by default.

Amp Slide Cart setup: Install → configure drawer styling → set up free-shipping bar → connect upsell rules → optionally install Amp Bundles, Back in Stock, Post Purchase. Realistic time for slide cart alone: 10-20 minutes. For the full suite: 1-2 hours.

The Amp setup time isn’t bad, but the Cartylabs flow is dramatically shorter for merchants who don’t have a developer on call.

Analytics#

Cartylabs: Cart-to-checkout rate, AOV, items-per-cart, upsell impression / click / accept rate, rewards-bar unlock rate, per-product upsell attribution, mobile-vs-desktop split. Updates daily. Built into the app dashboard.

Amp: Per-app analytics — slide cart shows drawer engagement and upsell accept; Bundles shows bundle revenue; Post Purchase shows accept rate. Each app has its own dashboard, so cross-app attribution requires manual stitching or pulling from Shopify reports.

If you’re a numbers-driven merchant who wants one dashboard for the entire pre-checkout funnel, Cartylabs is the cleaner experience.

Mobile experience#

70% of Shopify traffic is mobile, and mobile drawer performance drives more conversion than any feature comparison suggests. See our Shopify mobile conversion optimization guide for the full playbook.

Both apps render full-width drawers on mobile with sticky checkout buttons. Both support swipe-to-close. Differences:

• Cartylabs pre-renders the drawer on page load for instant open. Amp Slide Cart lazy-loads, which can introduce a 100-300ms delay on slower devices.
• Cartylabs keyboard avoidance (when shoppers tap the promo code field on iOS Safari) is handled in CSS; Amp Slide Cart relies on default behavior, which occasionally hides the checkout button.

These are small details, but they compound. Mobile cart-to-checkout is the metric to watch when comparing.

Internationalization#

Cartylabs ships 16-language support and RTL out of the box. Amp Slide Cart supports a smaller language set and RTL is partial. For stores selling into Europe, MENA, or APAC, Cartylabs is the lower-friction pick.

When Amp is still the right call#

In fairness to a strong product family, pick Amp if any of these are true.

• You need cart drawer + bundles + back-in-stock + post-purchase from one vendor and you don’t want to think about app sprawl.
• Your bundle strategy is sophisticated enough that you want a dedicated bundles app, not rewards-bar mechanics.
• You’re in the US/CA market and don’t need RTL or extensive language support.
• You want the most-installed slide cart with a 5.0 rating and don’t need the deepest AI recommendations.

For everyone else — especially merchants who want one embed instead of four apps — Cartylabs is the simpler stack.

Decision tree#

• You only need a cart drawer → flip a coin between Amp Slide Cart and Cartylabs; both are excellent on the core. Pick Cartylabs if you want the option to grow into rewards, AI, and countdowns without adding apps.
• You need cart + bundles + back-in-stock + post-purchase → Amp suite.
• You need cart + AI upsells + stacked rewards + countdowns → Cartylabs.
• You’re international → Cartylabs.
• You’re US-only and bundle-heavy → Amp.

A short summary#

Amp and Cartylabs solve “I have too many apps” from opposite ends. Amp is wider — four apps under one vendor. Cartylabs is deeper — one embed that replaces four pre-checkout tools. Neither is universally better; the right pick depends on whether you also need post-purchase, back-in-stock, and dedicated bundles UI.

If your bottleneck is the pre-checkout funnel and you want a single embed handling drawer, AI upsells, stacked rewards, and analytics, Cartylabs is the cleaner answer.
