12 Best Frequently Bought Together Shopify Apps in 2026

Amazon makes about 35% of its revenue from “Frequently Bought Together” recommendations — that one little box at the bottom of every product page showing 2 to 3 items you might also want. Three items. One click. Done.

Your Shopify store can do the exact same thing.

The problem? There are 50+ Frequently Bought Together Shopify apps competing for your install. Most articles ranking for this keyword are written by app companies pushing their own product to #1. Pricing is outdated. Cons are hidden. Real merchant complaints get buried.

We tested 12 apps the way an actual store owner would. We pulled live ratings from the Shopify App Store, checked which apps still hold the Built for Shopify badge, and read the angry 1-star reviews — not just the happy ones.

Let’s get into it.

TL;DR — Quick Picks for Busy Founders

• Best overall (FBT + Conversion features in one app): Oxify Cart Drawer & Upsells
• Best pure-play FBT widget: Frequently Bought Together by Code Black Belt
• Best free plan: Selleasy by Logbase
• Best for post-purchase: ReConvert / Upsell.com
• Best AI personalization: Wiser (read the billing fine print first)
• Best all-in-one (40+ tools): Vitals
• Best fair-pricing model: Zoorix

What Is a Frequently Bought Together App?

A Frequently Bought Together app shows shoppers 2 or 3 products that complement the item they’re already viewing. Usually with a small bundle discount and a one-click “Add all to cart” button. Sometimes called “Customers Also Bought” or “Complete the Look.”

It’s the digital version of the cashier asking: “Want fries with that?”

The first store to do this at scale was Amazon, which is why most Shopify FBT apps explicitly call themselves “Amazon-style Frequently Bought Together.” The format works because it lines up with how shoppers actually think: when I buy a camera, I probably also need an SD card and a case.

Why FBT Apps Work (Psychology + Data)

• Existing intent. You’re not interrupting the shopper. They already want the main item. You’re just showing them what completes it.
• Decision shortcut. No more thinking “what else do I need?” The widget answers it instantly.
• Anchoring. Three items at “$45.99 (save $8)” feels like a deal. One item at $19.99 feels normal.
• Social proof. The phrase “frequently bought together” implies other shoppers have already validated this pairing.
• Inventory movement. Pair best-sellers with slow-moving high-margin SKUs to clear stock and lift margin at the same time.

The average cart abandonment rate sits around 70%. FBT widgets work before the cart page, which is exactly when you have the most attention and the least hesitation.

Does Shopify Have a Frequently Bought Together Feature Built In?

Kind of.

Shopify’s free Search & Discovery app lets you manually pin “complementary products” to product pages. It’s free. It works for basic complementary suggestions.

But it’s missing three things any serious FBT setup needs:

• No bundle discount. Shoppers see related products with no pricing incentive.
• No one-click “Add all to cart.” Each product has to be added separately.
• No analytics. You can’t see what’s converting and what’s dead weight.

For a hobby store doing under 30 orders a month, the native option is fine. Anyone trying to actually grow Average Order Value (AOV) will outgrow it within a week.

The Discount Rule

Here’s the most important thing in this entire guide:

A Frequently Bought Together widget without a bundle discount converts almost no one. The same widget with a 5–10% bundle discount can lift AOV by 8–35%.

The discount is the lever. The widget is just the delivery vehicle.

I’ve seen stores install the most expensive premium FBT app on the market, leave the discount field empty, and wonder why nothing happened. I’ve also seen stores install a free app, add a 10% bundle discount, and lift AOV by 22% in two weeks. The app you pick matters less than this single setting.

If you only remember one thing from this article, remember that.

The 12 Best Frequently Bought Together Shopify Apps in 2026

1. Oxify Cart Drawer Cart Upsell — Best Overall

View on Shopify App Store →

• Rating: 5.0 ★ (32 reviews — 97% five-star)
• Pricing: From $19.99/mo
• Free trial: 14 days
• Free plan: No
• Built for Shopify: ✅ Yes
• Launched: January 2024

Real 30-Day Performance Data (Live Merchant Store)

This is real performance data from one merchant running Oxify in April 2026. Not a marketing illustration. Not a hand-picked best case. Just the dashboard view from one active store:

• Total upsell revenue (30 days): $3,107.46
• Orders with FBT attached: 12
• Average upsell value per FBT order: $258.95
• FBT widget alone: $671.86 in 30 days
• Product page cross-sell offer: $1,132.60 in 30 days
• Active offers running: 8 simultaneous upsells across product page and cart

For context: this is one mid-size store. The math says even at the conservative end, Oxify’s FBT and product page offers generate enough revenue in a month to pay for the app for an entire year — about 12x return on the $19.99/mo subscription, in 30 days, from one merchant.

This is the kind of data competitor articles never show you. Most “Best FBT app” lists don’t include a single screenshot of an actual app dashboard. We’re showing you the numbers because the numbers are the entire reason FBT exists.

Why Oxify is #1 (Beyond It Being Our App)

Most apps on this list are single-feature. You install Code Black Belt for the FBT widget. Then a second app for the cart drawer. Then a third for free gifts. Then a fourth for post-purchase upsells. Four apps. Four monthly fees. Four sources of theme bloat. Four support teams to manage. Four uninstalls when something breaks.

Oxify gives you all of it in one app:

• AI-powered Frequently Bought Together on the product page with one-click bundle add
• In-cart cross-sells and upsells inside the slide cart drawer (this is the rare differentiator — most FBT apps stop at the product page)
• Free shipping bar with tiered and multi-progress rewards
• Free gifts — auto-applied or manual selection
• BOGO and volume discounts / quantity breaks
• Sticky cart, countdown timer, trust badges
• Product page upsell with custom add-on configurations
• Upselling with discount codes inside the cart
• Post-purchase upsell funnel with full attribution analytics
• Shipping protection revenue add-on
• In-cart subscription upgrades (turn one-time buyers into subscribers)

App Stack Replacement Math

Most competitors only replace 1 app. Oxify replaces 4–5. Here’s the math from a typical Shopify stack:

What you’d typically pay for	Monthly cost
FBT widget app (Code Black Belt)	$19.99
Cart drawer app (Slide Cart, UpCart)	$29.99–$49.99
Free gifts app	$19.99
Free shipping bar	$9.99
Post-purchase upsell app	$19.99–$29.99
Total stack	$99.95–$149.95/mo
Oxify replaces all of it	$19.99–$79.99/mo

For a store doing 500 orders/mo, that’s roughly $1,200/year in app subscription savings — before you even count the AOV lift.

Why I Built Oxify This Way

I started Oxify in early 2024 because I was tired of seeing merchants I knew run six apps to do what should be one job. Every additional app is another point of failure, another billing line, another speed penalty, another support email when something breaks during Black Friday.

The Frequently Bought Together widget shouldn’t live in a separate silo from the cart drawer. The cart upsell shouldn’t live separately from the free shipping bar. The post-purchase upsell shouldn’t be a completely different team’s product. They’re all part of one journey: the moment between “I’m interested” and “I’m done buying.”

Oxify is built around that journey instead of split across it. That’s the entire pitch.

Pros

• One BFS-certified app replaces 4–5 single-feature tools — your Shopify admin stays clean and your speed score stays high
• Flat tiered pricing — $19.99 → $29.99 → $49.99 → $79.99 → $99.99 → $149.99 based on order volume. No revenue share. No surprise charges. No percentage of total store revenue.
• FBT works on product page — most competitors only do one location
• In-cart subscription upgrade is genuinely rare in this category — flip one-time buyers into recurring revenue without a separate subscription app
• Native Shopify checkout integration — no theme conflicts, no speed penalties, no third-party scripts blocking your store
• 14-day free trial, no credit card required, easy uninstall — no risk

Cons

• No free plan — entry tier is $19.99/mo (Selleasy and Zoorix have real free plans for stores under 50 orders/mo)

Best Store Types for Oxify

Oxify works particularly well for:

• Beauty and skincare — natural FBT pairings (cleanser + serum + moisturizer); see our FBT for beauty products guide
• Fashion and apparel — outfit completion, color-matched accessories
• Supplements and wellness — bundle protocols (multivitamin + protein + creatine)
• Food and beverage — meal kits, sampler packs
• Home and lifestyle — coordinated sets (sheets + pillowcases + duvet)
• Subscription-friendly products — coffee, supplements, beauty (use the in-cart subscription upgrade)

If your store does 50–5,000 orders/mo and you want one app to handle FBT, cart drawer, free gifts, and post-purchase — Oxify is built for you.

Setup Time

Most merchants are live in under 10 minutes. Install → enable theme embed → pick FBT products (or let AI do it) → set 5–10% bundle discount → publish.

2. Frequently Bought Together by Code Black Belt — Most Established Pure-Play

• Rating: 4.9 ★ (1,082 reviews)
• Pricing: $19.99/mo flat (or $199.90/year — saves 17%)
• Free trial: 30 days
• Free plan: No
• Built for Shopify: ✅ Yes
• Launched: March 2017

This is the original. The closest thing on Shopify to Amazon’s actual FBT engine. If anyone has earned the “Amazon-style frequently bought together Shopify” headline, it’s Code Black Belt.

What They Do Better Than Anyone

The algorithm. Code Black Belt has been crunching Shopify order data since March 2017 — that’s nearly a decade of pattern recognition across millions of merchant transactions. When you install their app, the AI immediately leverages that historical training to recommend pairings that make statistical sense, even on a new store with limited order history of its own.

This is something newer apps (including Oxify) can’t fake. We can write better recommendation logic, but we can’t replicate 9 years of training data overnight.

Feature Set

• AI-driven Amazon-style FBT widget on product pages
• Manual override system to push specific bundles
• 4 bundle discount types — percentage off, fixed amount off, free item, free shipping
• Widget customization with CSS controls for colors, fonts, and layout
• Native review app integration — works flawlessly with Judge.me, Loox, Yotpo, Stamped (star ratings render directly inside the FBT widget)
• Unlimited products, orders, and traffic at the flat $19.99 price
• No-code installation — works on any Shopify theme

Pros

• Most mature FBT algorithm on Shopify — 9+ years of training data
• Flat $19.99/mo regardless of order volume — predictable, no scaling surprises
• Yearly plan option saves 17% ($199.90/year vs $239.88 monthly)
• 30-day free trial is genuinely generous
• Battle-tested support reputation — they answer tickets quickly and with depth
• 1,082 reviews at 4.9 stars is one of the strongest social proof signals in the entire Shopify App Store
• Built for Shopify badge since the program launched

Cons

• Only does FBT on the product page. No cart upsell. No checkout. No post-purchase. No free gifts. No free shipping bar. If you want any of those, you’ll need separate apps.
• $19.99 for a single feature feels expensive next to multi-feature apps at the same price. Oxify charges the same and gives you 17 features. Vitals charges $10 more and gives you 40+.
• Analytics are basic — no funnel-level tracking, no cohort analysis, no A/B testing
• Customization options are limited compared to newer competitors
• No free plan — minimum spend is $19.99/mo

Real Merchant Use Cases

Code Black Belt is the right pick for:

• Established stores doing 1,000+ orders/mo that already have separate cart drawer and post-purchase apps and just need a battle-tested PDP widget
• Stores selling complex products where the AI’s deep training matters (electronics, technical equipment, niche hobbies)
• Merchants who want to install one thing and never touch it again — set it, forget it, watch AOV climb

Best for

Established Shopify stores that want a pure-play, battle-tested product page upsell Shopify widget with the most mature AI in the category — and don’t need cart, checkout, or post-purchase coverage from the same app.

3. Selleasy by Logbase — Best Free Plan

• Rating: 4.9 ★ (2,176 reviews)
• Pricing: Free up to 50 orders/mo → $9 → $19 → $29
• Free trial: 30 days on paid tiers
• Free plan: ✅ Yes (≤50 orders/mo)
• Built for Shopify: ✅ Yes
• Launched: July 2021

If you’re a new store on a tight budget, start here. The free tier is real and genuinely usable, not a marketing trap.

What Makes Selleasy Stand Out

Selleasy is owned by Logbase, an established Shopify ecosystem company that runs multiple apps in the upsell and order management space. That parent company depth shows up in two places: the product is mature beyond its 2021 launch date because the Logbase team brought patterns from their other apps, and the support team is one of the most responsive in the entire FBT category.

The other thing Selleasy does well is touch-point coverage. While Code Black Belt gives you FBT on the product page only, Selleasy spreads upsells across the whole journey:

• Amazon-style FBT bundles on product pages
• Product add-ons in list, grid, or carousel layouts
• Cart upsell pop-up funnels when items are added
• Checkout upsell extensions for Shopify Plus stores
• Post-purchase upsell offers
• Thank-you page upsells
• AI ChatGPT-powered recommendation engine
• AI Stylist for fashion stores (curates outfit pairings)

Pros

• True free plan up to 50 orders/mo — actual merchants run their entire stores on the free tier
• Widest set of upsell touchpoints on this list — product, cart, checkout (Plus), post-purchase, thank-you
• 2,176 reviews at 4.9 means it’s been stress-tested across thousands of stores including Black Friday peaks
• Multi-language and multi-currency out of the box — strong for international stores
• Built for Shopify badge signals real quality
• AI ChatGPT engine brings modern recommendation logic
• AI Stylist for fashion is a unique vertical-specific tool
• Logbase ecosystem means strong roadmap and frequent updates

Cons

• Pricing tied to total store orders, not just orders Selleasy generated — so you pay more even on orders the app didn’t influence
• UI gets busy when you turn on multiple offer types simultaneously
• Some merchants need support help to get the styling consistent with their theme — the design controls aren’t quite as polished as Oxify’s
• AI is newer than Code Black Belt’s — less institutional training data
• Fashion-specific features (AI Stylist) are great if you sell fashion, neutral otherwise

Real Merchant Use Cases

Selleasy is the right pick for:

• Pre-launch and new stores doing 0–50 orders/mo that need a free option that won’t lock them into bad habits
• Growing stores in the $9–$19/mo budget range that want full-funnel coverage
• Multi-language stores selling internationally (the multi-language UI is genuinely useful)
• Fashion stores that benefit from the AI Stylist vertical feature

Best for

New and growing stores wanting Frequently Bought Together plus broader upsell touchpoints across the full journey — without putting a credit card on file. Also a strong pick for international stores running multiple languages.

4. Wiser AI

• Rating: 4.9 ★ (490 reviews)
• Pricing: Free up to 50 orders → $9 → $19 → $49
• Free trial: 14 days on paid tiers
• Free plan: ✅ Yes
• Launched: April 2017

Wiser leans hard on AI. The pitch is per-visitor personalization — instead of showing every shopper the same FBT bundle for a given product, Wiser tracks individual behavior and tailors the recommendation to that specific shopper’s browsing history.

What Makes Wiser Different

Most FBT apps recommend at the product level: “Customers who bought Product A also bought B and C.” Wiser layers in shopper-level signals — what categories you’ve browsed, what you’ve added to cart before, how you’ve moved through the store. The result is FBT recommendations that vary visitor to visitor for the same product page.

For high-traffic stores with rich behavioral data, this can move the needle meaningfully. For low-traffic stores, it falls back to category-level patterns and bestseller logic.

Feature Set

• Per-visitor AI personalization for FBT and cross-sell
• Smart fallback logic — if AI doesn’t have enough behavioral data, it shows bestsellers instead of nothing
• A/B testing built in — test different widget designs and product mixes
• Multi-page deployment — works on home, product, cart, checkout, post-purchase, AND email
• Deep analytics dashboard with conversion tracking and revenue attribution
• Shopify Markets, multi-currency, multi-language
• Dedicated success manager for Shopify Plus tier

Pros

• Per-visitor personalization is genuinely more advanced than most competitors
• Smart fallback logic prevents empty FBT slots on new products
• A/B testing is rare in this price tier
• Full-journey coverage including email recommendations
• 490 reviews at 4.9 is a solid social proof base

Cons (Read Carefully)

This is the section where Wiser gets honest treatment most articles skip:

• Multiple recent reviews flag billing tied to total store revenue, not just sales the app actually attributed. Several merchants report charges that didn’t match their app-attributed revenue. Read the billing terms in detail before installing — this is the most-flagged complaint in their recent review feed.
• Aggressive post-uninstall outreach — multiple merchants report receiving emails and phone calls after uninstalling, which is unusual for a Shopify app
• Pricing tied to monthly orders rather than app-generated revenue — so you pay more even on orders Wiser didn’t influence
• Built for Shopify badge is not currently visible on the listing in some markets — verify before you commit to the AI claims
• Setup is more technical than simpler apps — the personalization controls require more configuration

Real Merchant Use Cases

Wiser is the right pick for:

• Stores doing 1,000+ orders/mo with enough behavioral data for per-visitor AI to actually matter
• Merchants comfortable reading billing fine print and willing to monitor charges monthly
• High-AOV stores where personalization lift can justify the higher tiers ($49+/mo)
• Stores using email + on-site personalization together — Wiser is one of the few that does both well

Best for

Mid-to-large stores comfortable reading billing terms carefully who want a dedicated AI-personalized recommendations engine across the full funnel including email. Skip if budget predictability is a hard requirement.

5. ReConvert / Upsell.com

• Rating: 4.8 ★ (~2,851 reviews)
• Pricing: Free plan available; paid from ~$4.99/mo
• Free trial: 30 days
• Free plan: ✅ Yes
• Built for Shopify: ✅ Yes

ReConvert dominates the post-purchase niche. The thank-you page is their playground. If you specifically want to focus on post-purchase upsell apps for Shopify, they’re hard to beat — though FBT is a secondary feature for them, not the core.

What ReConvert Does Best

Most upsell apps focus on the product page or cart. ReConvert focuses on the moment after purchase — when shoppers have already committed, their card is in hand, and friction is at its lowest. Their drag-and-drop funnel builder for the thank-you page is the most advanced in the category, and their one-click post-purchase upsells merge into the original order so customers don’t get double-charged or have multiple tracking numbers.

For FBT specifically, ReConvert uses Shopify’s recommendations API on the product page and cart, which is solid but not as sophisticated as Code Black Belt or Wiser. Where they shine is bundling FBT-style cross-sells with their post-purchase funnel logic.

Feature Set

• Frequently Bought Together via Shopify recommendations API on PDP and cart
• Cart upsell offers triggered on add-to-cart
• One-click post-purchase upsell with order merge (no double charge)
• Thank-you page funnel builder — drag-and-drop with conditional logic
• Checkout blocks for Shopify Plus stores
• AI-driven offer logic for post-purchase
• Customer birthday collection for email re-marketing
• Survey widgets for post-purchase data capture

Pros

• 2,851 reviews — one of the largest install bases in the upsell category
• Strongest drag-and-drop post-purchase funnel builder on Shopify
• Order merge means post-purchase upsells don’t create separate orders
• Generous free plan to test before committing
• AI offer logic combines well with FBT for compounding lift

Cons

• Pricing scales aggressively at high order volumes — what starts at $4.99 can balloon at scale
• Public controversy in 2025 about ad placements appearing on merchant checkout pages — the team has officially addressed this, but it’s worth knowing if you’re enterprise-grade or compliance-sensitive
• FBT is a side feature here, not the core — if FBT is your primary need, dedicated apps will outperform
• Setup complexity for the funnel builder is higher than simpler FBT-only apps
• Recent rebrand to Upsell.com has caused some merchant confusion about what’s the same app vs. a new product

Real Merchant Use Cases

ReConvert is the right pick for:

• Stores where post-purchase is the priority — DTC brands maximizing LTV
• Subscription-adjacent businesses that want to upgrade one-time buyers post-checkout
• Established stores with stable AOV that want to extract more from existing orders
• High-volume stores comfortable with revenue-share pricing

Best for

Stores where the post-purchase moment is the priority and Frequently Bought Together on PDP is a secondary need. If FBT is your main goal, pair this with Oxify or Code Black Belt instead.

6. Bold AI Upsell & Cross-Sell

• Rating: ~4.7 ★
• Pricing: From ~$9.99/mo, scales on offer views
• Free trial: 14 days
• Free plan: No
• Built for Shopify: ✅ Yes

Bold is one of the original Shopify upsell apps — they’ve been in the ecosystem since the early days and have one of the largest customer success teams in the category. If you want enterprise-style support and integrations, Bold is the safest pick on this list.

What Bold Does Differently

The biggest differentiator: in-checkout upsells for Shopify Plus stores. Most FBT apps stop at the cart page because Shopify restricts checkout customization to Plus merchants and Bold is one of the few apps with the partnership and infrastructure to deploy upsells inside the checkout flow itself.

For Plus stores, this is a meaningful competitive advantage — checkout is where conversion intent peaks, and Bold lets you slip a one-click upsell into that exact moment.

Feature Set

• Smart AI offers with manual override
• Manual upsell funnels for specific products or collections
• Frequently Bought Together bundles on product pages
• Order bumps at checkout (Plus only)
• “True” upsell — swap a customer’s selection to a higher-value SKU
• Cross-sell add-ons on product pages and cart
• Subscription upgrade offers
• Post-purchase upsells with order merge
• In-checkout upsells (Plus only)

Pros

• Long-running brand — one of the most established upsell apps on Shopify
• In-checkout upsells for Plus is a rare capability
• Full-funnel coverage including subscription upgrades
• Strong customer success team for enterprise clients
• Built for Shopify badge
• Smart AI combined with manual control gives flexibility

Cons

• The 2025 platform rebuild has had bugs. Multiple January 2026 reviews specifically flag checkout conversion drops after their update — some merchants reported drops as steep as 70% during the rebuild rollout. Verify current stability before installing.
• Pricing scales on offer views, which can balloon fast on high-traffic stores
• UI feels older than newer competitors like Oxify or Selleasy
• No free plan — you have to commit to a paid tier
• Setup complexity is higher than simpler FBT-focused apps

Real Merchant Use Cases

Bold is the right pick for:

• Shopify Plus stores that need in-checkout upsells (genuinely rare capability)
• Mid-to-large enterprise stores that want big-company support and SLAs
• Stores already invested in the Bold ecosystem (Bold has multiple apps that integrate)
• Subscription-adjacent businesses that need post-purchase subscription upgrades

Best for

Mid-to-large Shopify Plus stores that need in-checkout upsells and are willing to test current stability. For non-Plus merchants, Oxify, Selleasy, or Code Black Belt give you better value.

7. Honeycomb Upsell

• Rating: ~4.7 ★
• Pricing: Free → $49.99 → $99.99 → $149.99
• Free trial: 7 days

Honeycomb is built for performance marketers who actually run experiments. If you’re the kind of merchant who treats every FBT widget like a test variant and tracks conversion lift across cohorts, this is your tool.

What Honeycomb Does Best

Real A/B split testing. Most FBT apps that claim to have A/B testing only let you A/B different copy or designs — Honeycomb lets you test entirely different funnel structures against each other. Different products, different discount levels, different placements, different layouts. This is more rigorous experimentation than the rest of this list combined.

The drag-and-drop funnel builder is also one of the cleanest in the category, and their post-purchase order merge logic is mature (it predates ReConvert’s by years).

Feature Set

• Pre-purchase upsell funnels on product page and cart
• Post-purchase upsell funnels with order merge
• Thank-you page upsells
• AI auto-pilot for offer matching when you don’t have time to configure
• A/B split testing across funnels (not just copy)
• Drag-and-drop funnel builder
• Conditional logic — show different upsells based on cart contents, order value, customer segment
• One-click post-purchase upsell with order merge

Pros

• Real A/B funnel testing is genuinely rare in this category
• Clean drag-and-drop funnel builder rivals dedicated funnel platforms
• Mature post-purchase logic with order merge predates most competitors
• Conditional logic gives advanced control over offer triggers
• AI auto-pilot for merchants who don’t want to configure manually

Cons

• Free plan capped at 100 monthly funnel views — barely a tasting menu, not a real free tier
• Big jump from free to $49.99 with no middle tier (compare to Selleasy’s $9 entry)
• Some recent reviews report support response delays during peak hours
• No Built for Shopify badge currently visible
• Pricing tiers cap at $149.99 — high for a single-purpose app

Real Merchant Use Cases

Honeycomb is the right pick for:

• Performance-marketing-driven stores that test everything
• DTC brands with conversion specialists on staff who can run rigorous experiments
• Stores with $50k+ monthly revenue where A/B testing lift compounds enough to justify the price tier
• Merchants who want real funnel experimentation, not just copy variants

Best for

Performance-marketing-led stores ready to spend $50+/mo to A/B test offers and funnels seriously. If you’re not actually going to run experiments, save your money — Oxify or Selleasy gives you the same FBT capability at a lower tier without the experimentation overhead.

8. LimeSpot Bundle & Upsell AI

• Rating: 4.6 ★ (505 reviews)
• Pricing: Free → from ~$19.99/mo, scales with revenue
• Free trial: ✅ Yes
• Free plan: ✅ Yes
• Built for Shopify: ✅ Yes

LimeSpot has been doing personalization since before “personalization” became a marketing buzzword. They’re one of the longest-running AI recommendation engines on Shopify, with deep integrations across the platform.

What LimeSpot Does Best

The personalization layer goes deeper than competitors. Where Wiser personalizes per visitor based on session behavior, LimeSpot personalizes across visits, email, SMS, and on-site simultaneously — so a shopper who browsed certain products on email click-through gets matching FBT recommendations when they land on your store, then sees consistent product recommendations in follow-up email.

For multi-channel merchants running personalization as a strategy (not just a feature), this cross-channel consistency is genuinely valuable.

Feature Set

• AI recommendations across home, product, cart, checkout, post-purchase, and email
• Frequently Bought Together with bundle discounts
• Related items and complementary products
• Upsell + cross-sell on every page
• One-click checkout upsells for Shopify Plus
• A/B/n and multivariate testing (more rigorous than basic A/B)
• Multi-channel personalization — web, email, SMS
• Shopify Theme Editor integration for OS 2.0 themes
• Customer segmentation for targeted recommendations

Pros

• Long-established personalization engine with mature AI training
• Multi-channel consistency is genuinely rare on Shopify
• A/B/n and multivariate testing for serious merchandisers
• Deep Theme Editor integration for OS 2.0
• Built for Shopify badge
• Free plan available to test before scaling
• 505 reviews at 4.6 is solid social proof

Cons

• Revenue-based pricing has triggered surprise-charge complaints in recent 1-star reviews — some merchants report bills much higher than expected during high-revenue months
• Some merchants reported reliability issues during Black Friday 2025 peak hours — uptime during your biggest day of the year is non-negotiable; verify their current SLA
• Setup is more complex than the simpler apps on this list
• Lower rating (4.6) than top competitors at 4.8–5.0
• Multi-channel features require integrations (email/SMS) you may not already have

Real Merchant Use Cases

LimeSpot is the right pick for:

• Larger stores with multi-channel marketing — web, email, SMS personalization
• DTC brands where personalization is a strategy, not just a feature
• Stores with merchandising teams that run rigorous A/B/n tests
• Merchants ready to commit to a personalization platform, not just an FBT widget

Best for

Larger stores ready to commit to a full personalization platform across multiple channels. For merchants who just want FBT on the product page or cart, LimeSpot is overkill — Oxify, Selleasy, or Code Black Belt will be simpler and cheaper.

9. Zoorix

• Rating: 5.0 ★ (389 reviews)
• Pricing: Free → $7.99 → $14.99 → $29.99
• Free trial: 30 days
• Launched: December 2019

The pricing model alone makes Zoorix worth a look. Most apps in this category charge based on store revenue, total orders, or offer views — meaning you pay more even on orders the app didn’t influence. Zoorix charges only on revenue Zoorix actually generated.

What Zoorix Does Best

The pricing fairness is the headline feature. Zoorix tiers ($7.99, $14.99, $29.99) are tied to app-attributed revenue, not total store revenue. If Zoorix generates $5,000/mo in upsells, you pay the corresponding tier. If it generates $500/mo, you stay on a lower tier. This is how all upsell pricing should work, and almost no other app on this list does it.

The native cart drawer integration is also a real advantage — most FBT apps require a separate cart drawer app, but Zoorix’s cross-sell engine works inside their built-in cart drawer (similar to Oxify’s approach, just smaller scope).

Feature Set

• AI cross-sell on product page — Frequently Bought Together logic
• Native cart drawer with built-in cross-sell
• Fixed bundles with manual configuration
• Mix & match bundles for build-your-own
• Build-a-box — guided product selection bundles
• Volume discounts / quantity breaks / tiered pricing
• BOGO offers
• Free shipping thresholds
• Shop App Mix & Match integration — unique to Zoorix
• Real-time analytics dashboard

Pros

• Pricing tied only to Zoorix-generated revenue — fairest pricing model on this list
• 5.0 rating with 389 reviews is one of the strongest signals on this list
• Native cart drawer integration — FBT works inside the cart, not just on PDP
• Multiple bundle types in one app — fixed, mix & match, build-a-box, BOGO
• 30-day free trial before any paid tier
• Free plan available for new stores

Cons

• Smaller install base than top-tier competitors — 389 reviews vs 1,000+ for CBB or 2,000+ for Selleasy
• English-first UI (multi-currency works fine, but the merchant-facing interface is English-only)
• Fewer third-party integrations than Selleasy or Bold
• No Built for Shopify badge currently displayed — verify before assuming the speed/quality bar
• Less mature AI than 9-year-old engines like Code Black Belt

Real Merchant Use Cases

Zoorix is the right pick for:

• Bundle-heavy stores that sell kits, sets, or build-your-own configurations
• Cost-conscious merchants who want pay-only-on-results pricing
• Stores using Shop App (the Mix & Match integration is unique)
• Smaller catalogs under 500 SKUs where AI maturity matters less

Best for

Bundle-heavy stores that want fair, performance-based pricing and don’t mind a smaller install base. If you sell mostly bundle-style products and want native cart drawer integration without paying Oxify’s broader feature premium, Zoorix is a strong, honest pick.

10. Vitals: Reviews, Bundles & 40+

• Rating: 4.9 ★ (~2,622 reviews)
• Pricing: From ~$29.99/mo
• Free trial: ✅ Yes
• Built for Shopify: ✅ Yes

40+ features in one app. Reviews, bundles, BOGO, sticky cart, currency converter, visitor recordings, FBT, upsells, popups, social proof — Vitals tries to be the all-in-one Shopify toolkit, and for a lot of stores, it works.

What Vitals Does Best

Breadth. While Oxify focuses on the cart and conversion suite (FBT + cart drawer + free gifts + post-purchase), Vitals goes wider — they include reviews, currency conversion, visitor session recordings, and dozens of other tools alongside the FBT engine. For merchants who want one app to replace eight, Vitals is a serious option.

The trade-off is depth. The Vitals FBT engine is more basic than dedicated FBT apps, but for many stores, “good enough FBT in an app that also handles reviews, popups, and social proof” beats “best-in-class FBT plus seven other apps to manage.”

Feature Set

40+ tools across these categories:

• Reviews & UGC — product reviews, photo reviews, review request emails
• Bundles & Discounts — FBT, volume discounts, BOGO
• Cart & Checkout — sticky cart, currency converter, free shipping bar
• Conversion — visitor session recordings, abandoned cart, social proof
• Popups — exit intent, email capture, announcement bars
• AI Tools — product description generator, FAQ generator
• Trust Signals — trust badges, countdown timers, recently viewed

Pros

• Replaces 5–10 single-feature apps in your stack
• Fast load times despite the feature count — they’ve optimized for speed
• Constant feature updates — they ship new tools monthly
• One unified dashboard for all features
• 2,622 reviews at 4.9 is one of the strongest signals on Shopify
• Built for Shopify badge
• Generous free trial lets you test multiple features before committing

Cons

• The Frequently Bought Together engine is more basic than dedicated competitors like Code Black Belt or Wiser
• You’re paying for 40 features when most stores only use 5–8
• Some recent reviews call out customer service quality during setup issues
• Higher entry price ($29.99) than Oxify even though Oxify has more conversion-specific depth
• No cart drawer in the same way Oxify has — Vitals has add-on cart features but not a full cart drawer replacement
• Feature creep — having 40 tools available can lead to over-installation that bloats your store

Real Merchant Use Cases

Vitals is the right pick for:

• New stores that want one app to handle everything from launch
• Cost-conscious merchants who’d otherwise need 5–8 apps
• Stores that value breadth over depth — “good enough FBT + good enough reviews + good enough popups” beats juggling 8 separate apps
• Merchants who want a single dashboard instead of multiple admin tabs

Best for

New or scaling stores that want one app instead of a stack of ten — see our broader best Shopify apps roundup for context. If your priority is depth on FBT specifically, Code Black Belt or Oxify will outperform; if your priority is breadth across reviews, popups, and conversion, Vitals wins.

11. Essential Upsell & Cross Sell

• Rating: 5.0 ★ (~2,103 reviews)
• Pricing: Free plan available, paid tiers vary
• Free trial: ✅ Yes
• Built for Shopify: ✅ Yes

Don’t sleep on this one. Essential is one of the highest-rated upsell apps on Shopify (5.0 stars across 2,103 reviews) and has earned its Built for Shopify badge. If you’re looking for a free alternative to the paid tiers above, this is the strongest option after Selleasy.

What Essential Does Best

Simplicity and reliability. Essential doesn’t try to be everything — it focuses on FBT widget on product pages plus cart drawer cross-sells, executed cleanly, with a generous free plan and a Built for Shopify badge that signals real quality.

The 5.0 rating across 2,000+ reviews is one of the strongest social proof signals on Shopify in any category. Most apps with that volume of reviews drop to 4.7 or 4.8 — Essential has held 5.0, which means consistent quality, fast support, and few bugs.

Feature Set

• Frequently Bought Together widget on product pages
• Cart drawer cross-sell offers
• Post-purchase upsell funnels
• Manual and AI bundle configuration
• Bundle discount controls (% off, fixed amount, free shipping)
• Mobile-optimized widgets
• Multi-language support

Pros

• 5.0 rating with 2,103 reviews — exceptional social proof
• Built for Shopify badge
• Strong free plan for new stores
• Clean, fast UI — no bloat
• Reliable support reputation

Cons

• Less feature breadth than Oxify (no free gifts, no free shipping bar, no countdown timer)
• AI engine is less mature than Code Black Belt or LimeSpot
• Pricing transparency — paid tiers aren’t as clearly published as flat-fee competitors

Best for

New stores wanting a free, reliable, BFS-certified Frequently Bought Together app without the feature breadth of Oxify or Vitals. If your only need is FBT + cart cross-sell, Essential is one of the safest free picks on Shopify.

12. UFE Cross Sell & Upsell Bundle

• Rating: 4.8 ★ (~1,071 reviews)
• Pricing: Free plan available, paid tiers vary
• Free trial: ✅ Yes
• Free plan: ✅ Yes

UFE rounds out the list as a solid mid-tier option. Not the best at any single thing, but priced fairly and competent across the board.

What UFE Does Best

Flexibility on a budget. UFE bundles Frequently Bought Together, BOGO, volume discounts, and quantity breaks into a single app at low cost — making it a reasonable pick for merchants who want bundle variety without paying premium prices.

Feature Set

• Frequently Bought Together widget on PDP
• BOGO offers with flexible rules
• Volume discounts / quantity breaks
• Bundle deals with custom configuration
• Cart upsell offers
• Post-purchase upsell
• A/B testing capability

Pros

• 1,071 reviews at 4.8 — solid social proof base
• Free plan available
• Multiple offer types in one app
• A/B testing included even on lower tiers
• Fair pricing

Cons

• No Built for Shopify badge currently displayed — verify before installing
• Mid-tier in everything — not the best at any specific use case
• Smaller install base than top competitors
• Documentation is thinner than Selleasy or Oxify

Best for

Budget-conscious stores wanting flexibility across multiple offer types (FBT + BOGO + volume discounts) without committing to a premium app. If you want one specific thing done well, dedicated apps will outperform.

How to Choose the Right Frequently Bought Together App (3-Question Decision Framework)

Question 1: How many orders do you do per month?

• Under 50 orders: Selleasy free plan, Zoorix free plan, Essential free plan, or stick with Shopify’s free Search & Discovery
• 50 to 500 orders: Oxify Cart Drawer & Upsells ($19.99), Code Black Belt ($19.99), or Selleasy ($9–$19)
• 500 to 2,000 orders: Oxify Cart Drawer & Upsells (still flat-priced at $29.99–$49.99), Selleasy ($29), or Vitals ($29.99)
• 2,000+ orders / Shopify Plus: Oxify Cart Drawer & Upsells ($149.99), Bold (in-checkout for Plus), or LimeSpot

Question 2: Where do you want the FBT widget to appear?

• Product page only: Code Black Belt is purpose-built for this
• Product page + cart drawer: Oxify Cart Drawer & Upsells or Zoorix
• Full funnel (PDP → cart → checkout → post-purchase): Oxify Cart Drawer & Upsells, Selleasy, or Bold
• Email + on-site: LimeSpot or Wiser

Question 3: What pricing model fits your store?

• Flat fee no surprises: Oxify Cart Drawer & Upsells, Code Black Belt, Vitals
• Pay only on app-generated revenue: Zoorix
• Free start, scale later: Selleasy or ReConvert
• Avoid: Apps that take a percentage of total store revenue (read every billing page carefully)

AI Frequently Bought Together vs Manual Recommendations: Which Wins?

This is the question I get most often from merchants choosing between these apps.

AI works best when:

• You have 100+ products in your catalog
• You do at least 200 orders/mo (the algorithm needs data to learn from)
• Your product mix is diverse enough that pairings aren’t obvious
• You don’t have time for manual curation

Manual works best when:

• You have under 50 SKUs
• You do under 50 orders/mo (algorithm won’t have enough signal)
• You sell curated bundles where pairings are obvious (skincare routines, complete outfits, kit-style products)
• You want to push specific high-margin SKUs

The truth most articles won’t tell you: the highest-converting stores use both. AI handles the long tail of products you don’t have time to optimize. Manual pinning protects your bestsellers and high-margin SKUs from getting buried by algorithmic randomness.

Oxify Cart Drawer & Upsells, Selleasy, Wiser, and Code Black Belt all support hybrid (AI + manual) configurations. If you go with a manual-only app and your catalog grows, you’ll regret it.

How to Add Frequently Bought Together to Shopify (Step-by-Step)

If this is your first FBT install, here’s the 5-minute setup:

Step 1: Pick your app. Use the decision framework above. For most stores, Oxify or Selleasy is the right answer.

Step 2: Install from the Shopify App Store. Click “Add app,” approve permissions, done.

Step 3: Enable the app embed. Go to Online Store → Themes → Customize → App embeds. Toggle the FBT widget on. This makes it visible on your product pages.

Step 4: Configure your bundle products.

• For AI apps: Let the algorithm run for 7–14 days, then review and pin manual overrides on bestsellers.
• For manual apps: Pick your top 10 bestsellers and assign 2–3 complementary products to each.

Step 5: Set the bundle discount. This is the step that matters most. Set 5–10% off when all items are added. Without this, conversion will be near zero.

Step 6: Test on mobile first. 70%+ of Shopify traffic is mobile. If the widget is broken or hard to tap on mobile, fix that before optimizing desktop.

Step 7: Track results for 14 days. Look at AOV before vs after. Don’t make changes inside the first two weeks — the data needs to settle.

7 Tips to Maximize FBT Conversion Rate

1. Always include a bundle discount. 5% is the floor. 10% is the sweet spot. 15% is for high-margin categories. Without this, the widget is decoration.
2. Show 2 to 3 products. Not more. Decision fatigue kills FBT. Three is the magic number — the third item is where AOV lift compounds.
3. Pair logically, not randomly. Shampoo + conditioner + serum works. T-shirt + mug + phone case doesn’t. If the pairing doesn’t make sense in 1 second, it won’t convert. Read our deep-dive on FBT for beauty products for category-specific examples.
4. Pre-select all items by default. If shoppers have to manually check boxes, most won’t bother. Default-checked = default-bought.
5. Use savings language, not percentages. “Save $8” beats “10% off.” The brain processes dollar savings faster than math.
6. Test mobile separately from desktop. Most stores live or die on mobile. Make sure the widget is thumb-friendly.
7. Review your top FBT pairings monthly. Bestsellers shift. Seasonal products come and go. A pairing that worked in October may not work in February.

Common Mistakes That Kill FBT Performance

I’ve audited hundreds of Shopify stores. The same mistakes show up over and over:

• No bundle discount. Already covered. This is the #1 mistake. Fixing it alone can lift AOV 15%+.
• Too many products in the widget. Five products = decision fatigue. Stick to three.
• Random pairings from poorly trained AI. If you have under 200 orders/mo, manually pin your top 10 bestsellers.
• Hidden behind tabs or below the fold. FBT must be above or near the Add to Cart button. Below the fold = invisible.
• Mobile bugs. Widget renders fine on desktop, breaks on mobile. Test both.
• Ignoring the data. Most apps tell you which pairings convert. Most merchants never look. Check your cart upsell strategy guide every 30 days.

Realistic ROI: What AOV Lift to Expect

Let’s run the math.

If your store does $50,000/mo in revenue with an AOV of $60, that’s about 833 orders/month.

With a properly configured FBT widget plus a 10% bundle discount, expect:

• Conservative case (10% AOV lift): AOV moves from $60 → $66. Same order count. Monthly revenue moves from $50,000 → $54,978. +$4,978/mo ($59,736/year) in incremental revenue.
• Moderate case (20% AOV lift): AOV moves to $72. Monthly revenue → $59,976. +$9,976/mo ($119,712/year).
• Strong case (30% AOV lift): AOV moves to $78. Monthly revenue → $64,974. +$14,974/mo ($179,688/year).

At a $19.99/mo app cost, even the conservative case has a 249x ROI in the first month. This is the closest thing to free money in Shopify.

The Oxify dashboard data we showed at the top of this article (one merchant generating $3,107.46 in 30 days from FBT and product page offers) lines up directly with this math — it’s real evidence the AOV lift numbers above aren’t theoretical.

Frequently Asked Questions

Final Take

Frequently Bought Together isn’t a feature. It’s a system.

The app you pick matters less than:

• Picking complementary products (not random ones)
• Adding a 5–10% bundle discount (non-negotiable)
• Showing the widget where shoppers will actually see it
• Pre-selecting items so adding to cart is one click
• Reviewing performance every 30 days and pinning what works

Get those right and even a basic setup will outperform 80% of Shopify stores.

Get them wrong and even the most expensive app on this list won’t move your numbers.

The real Oxify dashboard data we shared at the top — $3,107.46 in 30-day upsell revenue, 12 FBT-attached orders, $258.95 average upsell per order — isn’t a marketing illustration. It’s what FBT looks like when you set it up correctly with the right app and a real bundle discount. The pattern repeats across every store that does this well.
