Amazon built 35% of its revenue on one mechanic: showing customers what other people bought alongside the product they were already viewing. Shopify does not include this natively at the level Amazon runs it. You need an app.
The average order value lift from a properly configured FBT widget runs between 8% and 35% depending on category, bundle structure, and whether a discount is applied. The discount is the key variable — without it, conversion rates drop to near zero.
This post ranks the 7 best Frequently Bought Together apps available on the Shopify App Store in 2026, based on features, pricing structure, review volume, and real merchant results.
Rating: 5.0★ | Price: From $14.99/mo | Free Trial: 14 days | Built for Shopify: Yes
Libautech Bundles & Upsell is the top-rated FBT app on this list for one reason: it gives merchants complete control over every element of the bundle experience without charging a percentage of revenue or capping orders. You pay a flat monthly fee and keep every dollar the widget generates.
The app offers both AI-powered and manual product selection. Manual selection is the better choice for fashion, apparel, and stores where the merchant knows their customers — the AI is more useful for large catalogs where curation at scale is impractical. The FBT widget renders in a standard horizontal three-product layout that mirrors Amazon's current format, or a full-width legacy layout for wider themes. Bundle discounts apply only when all selected items are in the cart, which creates the right incentive structure without undermining margin.
Used by over 2,000 merchants across 50+ countries. Holds the Built for Shopify badge, which means it meets Shopify’s highest standards for performance, design, and integration.
Best For: Merchants who want full control over their FBT widget, a flat pricing structure with no revenue caps, and a 5.0-star-rated app with the Built for Shopify badge.
Worst For: Merchants on a zero budget who cannot commit to a paid plan.

Rating: 4.9★ | Price: From $9.99/mo | Free Trial: 30 days | Developer: Code Black Belt
Frequently Bought Together by Code Black Belt is the most established app in this category. Its AI has been trained on over one billion orders across 90 million products, which gives it strong recommendation accuracy for stores with meaningful sales history. The app has generated over $1 billion in revenue across its merchant base and holds 4.9 stars across thousands of reviews.
The main limitation is pricing structure. Plans are tiered by order volume, which means a high-revenue store running significant bundle sales will move to higher pricing tiers. The manual bundle configuration has also been flagged by some merchants as less intuitive than newer competitors.
Best For: Stores with large catalogs and strong order history who want AI-driven recommendations without manual curation.
Worst For: High-volume stores who want predictable flat-rate pricing.
Rating: 5.0★ | Price: Free plan available, paid from $6.99/mo | Built for Shopify: Yes
Essential Upsell & Cross Sell holds a 5.0-star rating with over 2,000 reviews, making it the highest-rated free-entry app in this category. The free plan supports FBT widgets with basic customization. Paid plans add features like bundle discounts, A/B testing, and advanced analytics.
Best For: New Shopify merchants testing FBT before committing to a paid plan.
Worst For: Merchants who need granular bundle discount control and advanced analytics.
Rating: 5.0★ | Price: Free to install, scales by order volume | Built for Shopify: Yes
Kaching Bundles is primarily a volume discount and quantity break app, but it includes FBT functionality. With 3,800+ reviews and a 5.0-star rating, it has one of the strongest social proof profiles in the category.
Best For: Stores running volume discount strategies alongside FBT offers.
Worst For: Merchants who need dedicated FBT widget design control.
Rating: 4.9★ | Price: From $8.99/mo | Free Trial: 30 days
Selleasy supports FBT widgets, cart page upsells, and post-purchase offers from a single dashboard. If you want to run upsell logic across multiple touchpoints — product page, cart page, and thank-you page — without managing three separate apps, Selleasy handles all three. Pricing is flat-rate with no revenue cap.
Best For: Merchants who want to consolidate FBT, cart upsell, and post-purchase offers into one app.
Worst For: Merchants who only need an FBT widget and want the simplest possible setup.
Rating: 4.9★ | Price: From $9.99/mo | Free Trial: 30 days
Also Bought uses data mining algorithms to build a memory graph of purchase patterns across your store’s full sales history. It analyzes new orders and product updates in real time and has no limits on product count or order volume.
Best For: Established stores with large catalogs and significant sales history who want automated recommendations without manual curation.
Worst For: New stores with limited order history — the AI has little to learn from.
Rating: 4.9★ | Price: Free to install, scales by order volume | Built for Shopify: Yes
Fly FBT combines bundle offers, quantity breaks, and FBT widgets in a single app. The free-to-install entry point makes it accessible to merchants with tight budgets.
Best For: Budget-conscious merchants who want an all-in-one bundling solution to start.
Worst For: High-volume merchants who need predictable flat-rate pricing.
The right app depends on three variables: pricing structure, level of manual control, and store maturity.
If you want flat-rate pricing with no revenue caps and full design control, Libautech Bundles & Upsell is the strongest option. If you have a large catalog with strong order history and want pure AI automation, Frequently Bought Together CBB or Also Bought are worth testing. If you are just starting out and need a free entry point, Essential Upsell & Cross Sell removes the financial barrier while still delivering a functional FBT widget.
One universal rule: always add a bundle discount. A 10% discount applied when all FBT items are selected is the difference between a recommendation widget and an offer. Merchants who skip the discount see conversion rates near zero. Merchants who include it consistently report 8–15% AOV lift within 30 days.
A Frequently Bought Together widget displays complementary products on a product page alongside the item the customer is already viewing. When a bundle discount is applied, customers can add all items to the cart in one click at a reduced total price. The mechanic mirrors what Amazon has used for years to drive cross-sell revenue.
Shopify does not include a native FBT widget at the level needed for meaningful AOV impact. Shopify Search & Discovery offers basic product recommendations but does not support bundle discounts or one-click multi-add-to-cart. A dedicated app is required.
Prices range from free-to-install with order-based scaling to flat monthly fees between $8.99 and $19.99/month. Apps like Libautech Bundles & Upsell charge a flat monthly rate with no revenue cap. Apps like Kaching and Fly charge based on order volume, which means costs increase as your bundle sales grow.
Merchant data consistently shows that FBT widgets without a bundle discount produce near-zero add-on conversions. The discount is what transforms a product recommendation into an offer. A 10% discount applied when all items are selected is the most common configuration and delivers reliable AOV lift without significant margin impact.
Two to three products is the optimal range. Four or more creates decision fatigue on desktop and a cluttered layout on mobile, where over 70% of Shopify traffic originates. Stick to two or three complementary items that a customer would naturally consider buying on the same shopping trip.
Merchants running a properly configured FBT offer — with a bundle discount, two to three relevant products, and mobile-optimized styling — typically see AOV lift of 8–15% within the first 30 days. Stores in verticals with natural product pairings tend toward the higher end of that range.
For fashion stores, manual product selection outperforms AI recommendations because the merchant knows which items complete an outfit. Libautech Bundles & Upsell is the strongest choice — it supports full manual curation, custom section titles like Complete the Look or Wear It With, and granular design control to match any theme aesthetic.
Yes, but it is not always necessary. Apps like Selleasy handle FBT, cart upsells, and post-purchase offers from a single dashboard, reducing app overlap and potential theme conflicts. If you already have a dedicated post-purchase or cart upsell app, a standalone FBT app on the product page is a clean addition without duplication.
Frequently Bought Together widgets appear on individual product pages and allow customers to select complementary items from the recommendation set. Product bundles are typically pre-packaged sets with a fixed price or discount applied to the combination as a whole. Most top apps on this list — including Libautech and Kaching — support both mechanics under a single subscription.
