Last updated: April 2026 · Pricing verified April 22, 2026 · Reviewed by the Libautech team, builders of Bundles & Upsell and 8 other Shopify apps used by 5,000+ merchants across 50+ countries.
Most FBT app lists rank 10 tools by review count and recommend Frequently Bought Together CBB for everyone. That framing misses how FBT actually works. A manually curated fashion pairing ("complete the look with these shoes"), an AI-generated electronics cross-sell ("customers who bought this laptop also bought this bag"), a consolidated FBT-plus-upsell widget that extends across the full funnel, and a volume-break hybrid that combines FBT mechanics with quantity discounts all solve completely different FBT jobs — and the right app depends on catalog size, merchant maturity, and whether FBT is a standalone need or part of a broader upsell strategy.
The first job is manual FBT curation. The merchant knows which products genuinely complete the set — which shoes go with which dress, which accessories match which phone, which ingredients pair with which coffee bean. For categories where editorial judgment beats algorithmic pattern-matching (fashion, apparel, beauty, food/beverage, niche specialty stores), manual curation outperforms AI because AI only knows what other customers bought, not what the merchant's brand vision recommends. Manual FBT pairs well with sections titled "Complete the Look," "Perfect Match," or "Wear It With."
The second job is AI-powered FBT recommendations. For stores with large catalogs (500+ products) and strong order history (500+ completed orders), AI recommendation engines generate product pairings that no human could curate manually at scale. The AI analyzes purchase patterns and surfaces statistically high-conversion pairings in real time. Frequently Bought Together CBB's AI has been trained on over one billion orders across 90 million products; Also Bought Cross Sell uses data mining algorithms on full store sales history. For electronics, general merchandise, and large-catalog merchants, AI-driven pairings consistently beat manual curation.
The third job is FBT + broader upsell coverage in one app. For merchants who want FBT widgets on product pages plus cart upsells, post-purchase one-click offers, and Shopify Plus checkout extensions, a consolidated app covering all placements beats installing four specialists. Libautech Bundles & Upsell covers all four upsell placements under one flat-rate subscription, which means the complementary product rejected on the product page can be re-offered in the cart, on the thank-you page, or inside the Plus checkout flow — each placement catches a different subset of buyers.
The fourth job is FBT + volume-break hybrids. Some merchants need FBT recommendations combined with quantity discount mechanics — "buy these three products together and get 15% off, or buy 5+ of any single item for 20% off." Apps like Kaching Bundles and Fly FBT combine FBT widgets with quantity break tiers in one app, which works for consumable categories (supplements, coffee, cosmetics) where both mechanics make sense simultaneously.
This post ranks 8 apps across all four jobs with verified April 2026 ratings and pricing, and explains which combinations make sense for different store profiles.

Best for: Shopify stores that want FBT widgets combined with full upsell funnel coverage — product-page upsells, cart upsells, post-purchase one-click offers, and Shopify Plus checkout extensions — in a single flat-rate subscription with no revenue cap.
Libautech Bundles & Upsell holds 5.0 stars across 36 reviews with Built for Shopify certification. The FBT widget mirrors Amazon's current standard — three-product horizontal layout with checkboxes and one-click add-all-to-cart — or a full-width legacy layout for wider themes. The app supports both AI-powered product pairing and manual curation, which is the rare combination most FBT apps force merchants to pick between. Manual selection works best for fashion, apparel, and editorial-judgment categories; AI works best for large catalogs where scale makes manual curation impractical.
The pricing model is the strategic differentiator. Most FBT apps in this category scale cost with revenue — Kaching charges by order volume, Fly FBT scales with sales, and many competitors cap orders on free tiers. Libautech Bundles & Upsell uses flat monthly pricing with no revenue cap across all tiers. A store generating $100K/month from FBT bundles pays the same $14.99-49.99/mo as a store generating $500. At 20% AOV lift on $500K monthly revenue, even a 0.75% revenue share (common in upsell apps) costs $750/mo; Libautech's Unlimited tier captures the same functionality for $49.99/mo flat.
Core FBT features: manual product pairing with full merchant control (curate specific pairings for specific products), AI-powered pairing for large catalogs where manual curation is impractical, three-product horizontal layout matching Amazon's current standard, full-width legacy layout for wider themes, bundle discount control (discount applies only when all items in cart, creating proper incentive structure without margin damage), custom section titles ("Complete the Look," "Perfect Match," "Frequently Bought Together"), full design customization for colors, fonts, layout, and typography, and Built for Shopify certification meaning async loading with no Core Web Vitals impact.
Beyond FBT, the app extends into full upsell funnel coverage: cart upsells triggered by cart contents, post-purchase one-click upsells on the thank-you page (no re-entry of payment details required), Shopify Plus checkout extensions for in-checkout order bumps, support for both percentage and flat-dollar discounts, rule-based targeting for specific customer segments, and detailed analytics on accept/decline rates by placement.
Where it falls short: smaller review base (36) than category specialists like Frequently Bought Together CBB (thousands of reviews) or Kaching Bundles (1,800+) — merchants comparing review volume will see the gap, though the Built for Shopify badge and 9-app Libautech portfolio with 5,000+ merchants provide external validation. AI recommendation accuracy is weaker than Code Black Belt's AI for stores with 5,000+ orders of history because CBB has trained on over one billion orders across 90 million products — for catalogs of that scale with strong order history, CBB's specialization delivers better automated pairings. No genuinely free plan — $14.99/mo Starter is the entry tier, higher than Essential Upsell's free plan for stores validating FBT before committing budget. For stores needing only FBT without cart, post-purchase, or checkout upsell placements, simpler single-placement apps may be cheaper.
Pricing: Starter $14.99/mo. Pro $29.99/mo. Unlimited $49.99/mo. Flat-rate, no revenue cap. 7-day free trial on all tiers.
Best for: Shopify stores with large catalogs (500+ products) and strong order history (500+ completed orders) that want the category's most mature AI recommendation engine — trained on over one billion orders across 90 million products.
Frequently Bought Together by Code Black Belt (CBB) holds a 4.9+ rating across thousands of reviews and is the most established AI-powered FBT app on Shopify. The positioning: unlike newer AI apps that train on each store's individual purchase history, CBB's AI has been trained on aggregate data across its entire merchant base — over one billion orders across 90 million products — which means even new stores with limited data benefit from the collective pattern intelligence. The app has generated over $1 billion in revenue across its merchant base since launching in 2016.
The AI specialization matters for specific store profiles. Electronics, general merchandise, home goods, and large-catalog categories where statistical purchase patterns drive the best recommendations see the strongest results with CBB. Fashion, apparel, and editorial-judgment categories where the merchant's taste drives better pairings than historical data see weaker results — manual curation apps like Libautech or Essential Upsell outperform for those profiles.
Core features: AI-powered product pairing trained on aggregate merchant data, Amazon-style horizontal FBT widget on product pages, bundle discount application (percentage or flat-dollar), high-performance code optimized for peak traffic (handles flash sales without crashing), automatic theme style tuning for popular Shopify themes, manual recommendation override for specific products, post-purchase upsell support (upsell funnel after checkout), and random item fallback when AI lacks sufficient data for a specific product.
Where it falls short: pricing is tiered by order volume — high-revenue stores running significant bundle sales move to higher pricing tiers as they scale. At scale, this creates compounding cost that flat-rate apps like Libautech Bundles & Upsell avoid. Manual bundle configuration has been flagged by some merchants as less intuitive than newer competitors — the UI reflects 2016 design patterns that feel dated. AI accuracy depends on having sufficient purchase history; new stores under 500 orders see weaker recommendations than stores with 5,000+ orders. Design customization is less granular than Libautech or Fast Bundle. Not a good fit for fashion, apparel, or editorial-curation categories where manual pairing outperforms AI.
Pricing: Starter free plan. Professional $9.99/mo. Higher tiers scale with order volume. 30-day free trial on paid tiers.
Best for: Shopify stores with large catalogs and significant sales history that want AI recommendations updating in real time as new orders come in — the data-mining alternative to CBB for established stores.
Also Bought Cross Sell uses data mining algorithms to build a memory graph of purchase patterns across each store's full sales history. Unlike CBB's aggregate-training model, Also Bought trains exclusively on the installing merchant's own purchase data — which produces more specific recommendations for that specific store but requires meaningful sales history for accuracy. The app analyzes new orders and product updates in real time with no limits on product count or order volume, meaning established stores with deep catalogs benefit most.
Core features: data mining algorithm analyzing full sales history, real-time updates as new orders come in, multiple recommendation types (automatic, manual, featured by collection or vendor), no limits on product count or orders processed, 30-day free trial for comprehensive testing period, integration with standard Shopify themes, and widget display on product pages.
Where it falls short: no free plan after trial — paid subscription required from day 31. AI accuracy depends on existing sales data; stores with under 500 completed orders see weaker recommendations than established stores with 5,000+ orders of history. Less customization depth than Libautech or Fast Bundle for design matching. No bundle discount application — the widget is recommendation-only, not offer-based, which reduces conversion lift compared to FBT apps that include bundle discount mechanics. Better positioned as a CBB alternative for stores that want store-specific AI rather than aggregate-trained AI.
Pricing: 30-day free trial. Paid plans from $9.99/mo scaling with catalog size.
Best for: new Shopify stores testing FBT before committing to paid plans — the highest-rated free-entry FBT app with 5.0 stars across 2,060+ reviews and Built for Shopify certification.
Essential Upsell & Cross Sell holds 5.0 stars across 2,060+ reviews with Built for Shopify certification — one of the highest rated free-entry apps in the entire upsell category. The positioning: a genuinely functional free tier that lets new merchants deploy FBT widgets without any upfront cost, with paid tiers unlocking bundle discounts, A/B testing, and advanced analytics for stores that grow beyond free-plan limits.
Core features: Free plan with FBT widget on product pages, manual product pairing controls, custom widget styling to match store theme, Built for Shopify certification for Core Web Vitals performance, quick setup (widget live within minutes of install), A/B testing on paid tiers, advanced analytics on paid tiers, and bundle discount application on paid tiers.
The strategic value: for new stores under $5K/month running simple FBT strategies, Essential Upsell's free plan genuinely covers the need at zero cost. The paid upgrade path ($6.99/mo) is meaningfully cheaper than most alternatives, which makes it a natural entry point for merchants growing beyond free tier feature limits.
Where it falls short: bundle discount feature is locked to paid tiers — and since merchant data consistently shows FBT widgets without bundle discounts produce near-zero incremental conversions, the free tier functionally requires upgrade to deliver AOV lift. Design customization on free tier is more limited than paid-tier alternatives. Not a good fit for stores that need AI-powered pairing, multi-placement upsell coverage, or advanced rule engines.
Pricing: Free plan available. Paid plans from $6.99/mo. 7-day free trial on paid tiers.
Best for: Shopify stores wanting FBT widgets on product pages combined with cart upsells and post-purchase offers in one app with a genuinely functional free tier for validation before paid commitment.
Selleasy holds 4.9 stars across 2,283 reviews with Built for Shopify certification. The positioning is multi-placement consolidation: rather than installing separate apps for FBT, cart upsells, and post-purchase offers, Selleasy handles all three from a single dashboard. For merchants who want upsell logic across multiple touchpoints without managing three separate apps, Selleasy is one of the cleanest consolidation options.
The free tier stands out. Selleasy's free plan covers up to 50 orders per month with all features included and zero revenue share — genuinely enough to validate whether multi-placement upsells generate incremental revenue before committing budget. Most competing apps either cap free tiers at useless limits or charge revenue share on free tiers (disqualifying them as actually free). Selleasy's free plan is the closest to a genuine no-risk trial in the multi-placement upsell category.
Core features: FBT widgets on product pages with manual product selection, cart upsells with complementary product offers triggered by cart contents, post-purchase one-click upsells on the thank-you page, Shopify Plus checkout extensions on higher tiers, Amazon-style FBT recommendations, multi-language support for international stores, custom CSS for theme matching, and clean Built for Shopify performance (async loading, no Core Web Vitals impact).
Where it falls short: design customization depth is intentionally basic — stores wanting heavily branded upsell widgets with custom animations will find styling controls restrictive compared to Libautech or Fast Bundle. Free tier caps at 50 orders/mo; growing stores quickly outgrow the free tier and need to upgrade to paid plans. For post-purchase thank-you page specialization specifically, ReConvert's dedicated drag-and-drop editor is more powerful. Multi-placement focus creates more settings to manage than pure FBT specialists.
Pricing: Free plan (50 orders/mo, all features). Paid plans from $8.99/mo scaling with order volume.
Best for: Shopify stores in consumable categories (supplements, coffee, cosmetics, pet food) that want FBT recommendations combined with quantity break discount tiers — the hybrid specialist for "buy these together OR buy more for discount" mechanics.
Kaching Bundles holds 5.0 stars across 1,800+ reviews with Built for Shopify certification — one of the highest-rated and most-reviewed bundle apps on Shopify. The positioning combines FBT widgets with the app's primary specialty (quantity breaks): for consumable categories where customers routinely buy 2-3+ of the same item, Kaching lets merchants run both FBT (cross-category pairings) and quantity breaks (same-SKU tiered pricing) from one app with unified admin UI.
Core features: FBT widgets on product pages, tiered quantity breaks with up to 5 discount levels per product, BOGO deals with configurable trigger conditions, Buy X Get Y offers, volume discounts across product collections, customizable widget styling, fast loading with minimal page-speed impact, support for percentage or flat-dollar discounts at each tier, widget display on product pages and cart, and analytics tracking which tier thresholds convert best.
The 5.0 rating across 1,800+ reviews reflects consistent merchant satisfaction with support quality and setup speed — two areas where many bundle apps struggle. The setup is genuinely fast (most merchants report full configuration in 20-30 minutes).
Where it falls short: FBT is secondary to quantity breaks in Kaching's positioning — for stores where pure FBT widget control is the primary need, dedicated FBT specialists (CBB, Libautech) offer more granular FBT-specific controls. Order-based pricing scales monthly cost as sales volume grows, which creates compounding cost that flat-rate apps avoid at scale. Less customization depth than Fast Bundle's frontend controls. Not a good fit for merchants needing pure FBT without volume break mechanics.
Pricing: Free plan available. Paid plans from approximately $9.99/mo scaling with Shopify plan level.
Best for: Shopify stores that want FBT plus the broadest bundle-type variety in one app — 7 distinct bundle types including Fixed Bundles, Volume Discounts, Mix & Match, Cross-sell, BXGY, Add-ons, and AI-powered FBT with strong frontend widget customization.
Fast Bundle is the general-purpose bundle specialist that handles FBT plus six other bundle types in one app. The positioning: rather than picking FBT specifically and going deep, Fast Bundle handles every major bundle pattern (including FBT) with unified admin UI and consistent widget styling across all bundle types. For merchants who want FBT plus the ability to experiment with fixed bundles, mix-and-match, and quantity breaks without installing four different apps, Fast Bundle covers the breadth.
Core features: 7 bundle types including AI-powered Frequently Bought Together, Fixed Bundles, Volume Discounts, Mix & Match bundles, Cross-sell offers, Buy X Get Y deals, and Add-ons, Shopify POS integration, AI image generation for bundle landing pages, customizable bundle widgets that blend with any Shopify theme, bundle display on product pages, collections, cart, or as add-ons, and A/B testing for bundle offers.
Where it falls short: FBT depth is narrower than dedicated FBT specialists like CBB because Fast Bundle spreads development across 7 bundle types rather than going deep on one. Some merchant reviews flag UI glitches and restrictions on complex discount structures. AI features (image generation, bundle suggestions) depend on catalog size and purchase history — new stores see weaker AI recommendations. Free tier is a trial rather than permanent, unlike Shopify native Bundles or Essential Upsell. Pricing scales with order volume past entry tier.
Pricing: Free trial available. Paid plans from approximately $19/mo scaling with order volume.
Best for: Budget-conscious Shopify merchants who want an all-in-one bundling solution combining FBT, quantity breaks, and bundle discounts with free-to-install entry and order-volume-based pricing.
Fly FBT combines bundle offers, quantity breaks, and FBT widgets in a single app with a free-to-install entry point. The positioning: for merchants with tight budgets who want bundling functionality without upfront subscription commitment, Fly lets stores start free and scale up as order volume grows.
Core features: Built for Shopify badge, FBT widget on product pages, quantity breaks combined with FBT in one app, bundle discounts, customizable widget styling, free-to-install entry without trial limit, and integration with standard Shopify themes.
Where it falls short: order-based pricing means monthly cost rises with sales volume — at scale, this compounds faster than flat-rate alternatives like Libautech. Feature depth is narrower than Libautech, CBB, or Fast Bundle on advanced design customization. AI recommendation quality is weaker than CBB or Also Bought. Less granular discount logic than Libautech or Kaching. Better positioned as a budget entry point rather than a long-term home for growing stores.
Pricing: Free to install. Paid plans scale with order volume.
For FBT plus full upsell funnel coverage in one flat-rate subscription with no revenue cap: Libautech Bundles & Upsell. 5.0/36, Built for Shopify, $14.99/mo Starter, manual + AI selection, full design control, covers product-page FBT + cart + post-purchase + Plus checkout.
For the most mature AI recommendation engine on large catalogs with strong order history: Frequently Bought Together by Code Black Belt. 4.9+/thousands, trained on 1B+ orders, $9.99/mo entry, order-based pricing scales with volume.
For data-heavy stores wanting store-specific AI with real-time updates: Also Bought Cross Sell. 4.9+, data mining on full sales history, $9.99/mo entry.
For new stores testing FBT before paid commitment: Essential Upsell & Cross Sell. 5.0/2,060+, Built for Shopify, free plan available, $6.99/mo paid entry.
For FBT + cart + post-purchase upsells in one app with genuine free tier: Selleasy. 4.9/2,283, Built for Shopify, free plan covers 50 orders/mo, $8.99/mo paid entry.
For FBT combined with quantity breaks in consumable categories: Kaching Bundles. 5.0/1,800+, Built for Shopify, quantity break specialist with FBT included, $9.99/mo entry.
For FBT plus 6 other bundle types in one app with strongest frontend customization: Fast Bundle. 4.9+, 7 bundle types, AI FBT, $19/mo entry.
For budget merchants wanting all-in-one bundling at free-to-install entry: Fly Frequently Bought Together. 4.9+, Built for Shopify, order-based pricing.
For most Shopify stores doing $10K-100K/month, the honest recommendation depends on two variables. If you have a large catalog (500+ products) with strong order history (5,000+ completed orders) and want pure AI-driven pairing depth: Frequently Bought Together by Code Black Belt at $9.99/mo entry — but budget for tier upgrades as sales volume grows. If you want FBT plus broader upsell funnel coverage in one flat-rate subscription: Libautech Bundles & Upsell at $14.99-49.99/mo captures FBT plus cart, post-purchase, and Shopify Plus checkout placements for a flat fee that does not scale with revenue. For new stores validating FBT before committing budget: Essential Upsell free plan or Selleasy free tier (50 orders/mo) are the zero-cost starting points.
One universal rule across all FBT apps: 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. Merchant data consistently shows FBT widgets without bundle discounts produce near-zero incremental conversions; merchants who include the discount reliably report 8-15% AOV lift within 30 days.
This ranking is based on four criteria applied to every Shopify FBT app tested in 2026. First, Shopify App Store rating and verified review volume as of April 22, 2026 — the signal of long-term merchant satisfaction at scale. Second, which of the four FBT jobs each app solves best (manual curation, AI-powered recommendations, FBT + broader upsell coverage, FBT + volume-break hybrids) rather than a generic feature checklist — the strongest FBT strategies match app specialization to catalog size, merchant maturity, and category type. Third, pricing structure and total cost at realistic merchant volumes — flat-rate pricing (Libautech Bundles & Upsell) scales differently than order-volume-based pricing (CBB, Kaching, Fly), and the math differs meaningfully past $5K/month in FBT-driven revenue. Fourth, page-speed impact and Built for Shopify certification — FBT widgets load on every product page, so synchronous-script apps can add 200-500ms of page load time per app, and the compounding damage across multiple widgets can drop Lighthouse scores by 20-30 points.

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 35% of its revenue through cross-sell recommendations.
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, one-click multi-add-to-cart, or the visual layout that matches Amazon's FBT standard. A dedicated app is required for the specific mechanic that drives measurable AOV lift.
Prices range from free-to-install with order-based scaling (Fly FBT, Kaching) to flat monthly fees between $6.99 and $49.99/month. Libautech Bundles & Upsell ($14.99-49.99/mo) uses flat pricing with no revenue cap. Frequently Bought Together by Code Black Belt ($9.99/mo entry) scales with order volume. Essential Upsell offers a genuinely free plan for stores testing FBT before committing budget.
Yes. Merchant data consistently shows 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 reliably delivers 8-15% AOV lift within 30 days 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 60%+ of Shopify traffic originates. Stick to two or three complementary items that a customer would naturally consider buying on the same shopping trip.
Properly configured FBT widgets typically lift AOV 8-15% within the first 30 days, with best-performing configurations in categories with natural product pairings (electronics, beauty, supplements) hitting 20-35% AOV lift. The discount is the key variable — widgets without bundle discounts produce near-zero lift regardless of app quality.
For fashion stores, manual product selection outperforms AI recommendations because merchants know which items complete an outfit better than an algorithm does. 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.
AI-powered FBT wins for stores with large catalogs (500+ products) and strong order history (5,000+ completed orders) where manual curation at scale is impractical. Electronics, general merchandise, and home goods categories see the strongest AI-driven results because statistical purchase patterns generate better pairings than human editorial judgment at scale. Fashion, apparel, and beauty categories lean toward manual curation because brand taste beats aggregate statistics.
Yes, but consolidation often wins. Apps like Libautech Bundles & Upsell or 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 app like ReConvert, adding a standalone FBT app on the product page is a clean addition without duplication.
Frequently Bought Together widgets appear on individual product pages and let customers select complementary items from a 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 Bundles & Upsell, Kaching, and Fast Bundle — support both mechanics under a single subscription.
