Best In Cart Upsell alternatives for Shopify in 2026

Last updated: October 15, 2026. Pricing and ratings are taken from each app's Shopify App Store listing on that date.

Quick answer: the best In Cart Upsell alternative depends on what you need beyond the cart. UpsellPlus adds Shopify Plus checkout upsells, post-purchase funnels and subscription upgrades to cart offers. Upcart is a strong slide cart, and Candy Rack and Selleasy focus on add-ons.

Disclosure: UpsellPlus is our app. Competitor facts are taken from each app's Shopify App Store listing, and we say where each one is the better fit.

Why Shopify stores look for a In Cart Upsell alternative

In Cart Upsell (4.8 from 586 reviews) started with in-cart offers and now adds product page, checkout-click pop-up and post-purchase upsells. The most common reasons stores look elsewhere:

• Limited free plan. The free plan allows one offer and shows a watermark.
• No in-checkout offers listed. Shopify Plus stores that want offers inside checkout need another app.
• Subscription and testing depth. Stores that want subscription upgrades or holdout tests on top of cart offers.

For simple cart offers at a flat price, ICU remains a sensible option.

The 6 best In Cart Upsell alternatives

1. UpsellPlus

Choose it over In Cart Upsell if: You want cart and cart drawer offers plus Shopify Plus checkout upsells, post-purchase funnels and subscription upgrades in one app.

Rating: 5.0 (146) on the Shopify App Store.

• Offers chosen by hand, from collections or tags, or automatically by ShopBrain (similar, complementary, subscription upgrade, size upgrade, complete the set, clearance and more)
• Upsells to subscriptions with Shopify Subscriptions, Recharge, Appstle, Seal, Skio, Stay AI and other selling-plan apps
• 25 targeting rules, including Klaviyo segments, Shopify Markets, B2B and cart contents
• Multivariate A/B tests and holdout experiments that measure incremental revenue (on the $119 plans and up)
• Checkout customizations on Shopify Plus: styling, trust content, payment and delivery method visibility

Pricing: You can build and preview offers for free; going live needs a paid plan. Launch is $49/month (up to $500 in upsell revenue), Shopify Plus $119/month (up to $2,000, adds checkout upsells and A/B testing) and Scale $199/month (up to $5,000). No commission on sales; 14-day free trial on paid plans.

Watch out for: Checkout placements need Shopify Plus, as with every app that offers checkout upsells (a Shopify restriction).

2. Upcart

Choose it over In Cart Upsell if: You want a fully customizable slide cart with upsells, add-ons and a free-shipping bar.

Rating: 4.7 (959) on the Shopify App Store.

• Upsells and add-ons modules

• Announcements module
• Custom HTML and CSS

Pricing: $29.99/month up to 200 monthly store orders, then $34.99, $54.99 and higher as orders grow. 14-day free trial.

Watch out for: Priced by total store orders, and it covers the cart only, so checkout and post-purchase need another app (such as Aftersell).

3. Candy Rack

Choose it over In Cart Upsell if: You mainly want add-on pop-ups when a product is added to the cart, with a built-in slide cart.

Rating: 4.9 (262) on the Shopify App Store.

• Pop-up add-ons at add-to-cart
• Built-in slide cart
• Unlimited upsell orders and revenue
• 60-day money-back guarantee

Pricing: $29.99 (up to 50 orders), $39.99 (51–200), $59.99/month (201–500) and higher. 8-day free trial.

Watch out for: No checkout or post-purchase offers, so you'd pair it with another app for after the add-to-cart.

4. Selleasy

Choose it over In Cart Upsell if: You mostly need frequently bought together bundles and add-ons at a simple flat price.

Rating: 4.9 (2,747) on the Shopify App Store.

• Frequently bought together bundles and product add-ons
• Cart pop-up funnels and in-cart upsells
• Post-purchase and thank-you page offers

Pricing: Free under 50 orders/month, then $15, $49 or $99/month. Checkout upsells for Shopify Plus are on the Pro plan and up.

Watch out for: AI recommendations are capped per month by plan.

5. Zipify OCU

Choose it over In Cart Upsell if: You want pre- and post-purchase funnels with pricing tied to upsell revenue and a hard monthly cap.

Rating: 4.6 (567) on the Shopify App Store.

• Pre- and post-purchase one-click upsells
• Cart drawer and product page offers
• In-checkout upsells on Shopify Plus
• AI upsells and A/B testing

Pricing: $9.95/month up to $200 in upsell revenue, $25–$99 between $200 and $2,500, then from $149/month, capped at $999. 30-day free trial.

Watch out for: The monthly price moves with upsell revenue, so it is less predictable than a flat plan.

6. ReConvert

Choose it over In Cart Upsell if: You want post-purchase and thank-you page offers on a free or low-cost plan to start.

Rating: 4.8 (3,107) on the Shopify App Store.

• Post-purchase funnels and thank-you page builder
• Quantity breaks and upsell pop-ups

Watch out for: Pricing is based on all store orders, so the bill grows with your store even when upsells don't.

How to switch from In Cart Upsell

1. List your live In Cart Upsell offers and how much revenue each brings in.
2. Rebuild the top earners first in the new app, on the same placements.
3. Turn off In Cart Upsell's offers when the new ones go live, so shoppers don't see duplicates.
