The best Shopify product recommendation apps use purchase history, browsing behavior, and AI to suggest products customers actually want — not just items from the same collection. Stores using personalized recommendations typically see AOV increases between 10-30%, depending on catalog size and how well the suggestions match buying patterns.
Shopify's built-in recommendations cover the basics. But if most of your customers buy exactly one item and leave, a dedicated app can show targeted suggestions across your product pages, cart, checkout, and post-purchase — turning single-item orders into multi-product ones.
Here are the 7 best product recommendation apps for Shopify in 2026, ranked by what they do well and where they fall short.
1. Frequently Bought Together CBB
Best for: Amazon-style "bought together" bundles on product pages
Frequently Bought Together by Code Black Belt is one of the oldest and most focused recommendation apps on Shopify. It does one thing — suggest complementary products as a bundle on the product page — and does it well. The AI analyzes your store's sales history to automatically pair products customers tend to buy together.
You can also create manual bundles, set up percentage or fixed-amount discounts on bundle purchases, and customize the widget to match your theme. It works on product pages and cart pages, supports multiple languages, and has no limits on products, orders, or traffic.
- Rating: 4.9/5 (1,088 reviews)
- Pricing: $19.99/month flat — no usage tiers, no hidden fees
- Best feature: AI-generated bundles that improve over time as your sales data grows
- Limitation: Only covers product and cart pages. No checkout or post-purchase recommendations.
If your goal is simple, high-converting "frequently bought together" widgets without the complexity of a full personalization platform, this is the app to start with.
2. Rebuy Personalization Engine
Best for: Enterprise-level personalization across the entire customer journey
Rebuy is the most comprehensive recommendation engine on Shopify. It covers every touchpoint — product pages, cart, checkout, post-purchase, and even re-order landing pages. The AI engine learns from customer behavior and purchase history to serve personalized suggestions at each step.
The standout feature is Smart Cart, a fully customizable, AI-powered cart drawer that turns your cart page into a recommendation surface. Rebuy also supports A/B testing, so you can measure which recommendation strategies actually lift revenue.
- Rating: 4.7/5 (810 reviews)
- Pricing: Starts at $25/month (Build Your Plan), up to $538/month (Platform One with everything included). 14-30 day free trials.
- Best feature: Smart Cart with AI recommendations built directly into the cart drawer
- Limitation: Pricing scales quickly. The full platform costs $538/month, which only makes sense for stores doing significant volume.
Rebuy is built for stores that want end-to-end personalization and have the revenue to justify the investment. If you're specifically interested in post-purchase upsell strategies, that's where Rebuy's full-funnel approach pays off most. If you're under $50K/month in sales, the lower-tier plan works, but you won't access every feature.
3. LimeSpot: Upsell & Cross Sell
Best for: AI-powered recommendations with audience segmentation
LimeSpot takes a different approach than most recommendation apps. Instead of just analyzing purchase history, it segments your audience and serves different recommendations to different customer groups. A first-time visitor sees different suggestions than a returning customer who bought from a specific collection last month.
The app supports recommendations on product pages, cart, checkout, and post-purchase. The higher-tier Max plan adds audience segmentation and A/B testing. LimeSpot integrates with over 70 apps including Klaviyo and Yotpo.
- Rating: 4.6/5 (502 reviews)
- Pricing: Free up to 10 orders/month, then $9.99/month (Turbo). Max plan starts at $50/month and scales with revenue.
- Best feature: Audience segmentation that personalizes recommendations by customer type
- Limitation: The free tier's 10-order cap is very restrictive. Most stores will need the paid plan immediately.
4. Zoorix: Bundles & Cross Sell
Best for: Bundle-based recommendations with flexible discount structures
Zoorix combines product recommendations with bundle creation. You get AI-driven cross-sell suggestions alongside mix-and-match bundles, BOGO offers, and volume discount tiers. It's particularly useful if your recommendation strategy relies on bundling products together rather than showing standalone suggestions.
The app supports multi-currency and multi-language, works in the cart drawer, and integrates with Shopify's native checkout. The free plan includes core features, making it one of the more accessible options for smaller stores.
- Rating: 5.0/5 (389 reviews)
- Pricing: Free plan available. Paid plans: $7.99, $14.99, or $29.99/month with 30-day free trials.
- Best feature: Mix-and-match and build-your-own-bundle options alongside standard recommendations
- Limitation: The recommendation engine is secondary to the bundling features. If you want pure AI-driven product suggestions without bundling, other apps are more focused. (See our best Shopify product bundle apps roundup for more bundling options.)
5. Also Bought CBB
Best for: Stores that want "customers also bought" without the bundle discount mechanics
Also Bought is the sibling app to Frequently Bought Together, built by the same developer (Code Black Belt). Where Frequently Bought Together focuses on bundle discounts, Also Bought shows product suggestions without requiring a discount incentive. It's closer to Amazon's "customers who bought this also bought" widget.
The app offers multiple recommendation types: automatic (AI-driven), manual, recently viewed, and collection-based. It works on both product and cart pages with a fully customizable UI.
- Rating: 4.8/5 (356 reviews)
- Pricing: $19.99/month (or $199.90/year, saving 17%). 14-day free trial.
- Best feature: Multiple recommendation types in one app — automatic, manual, last-seen, and collection-based
- Limitation: No checkout or post-purchase placement. Similar pricing to Frequently Bought Together without the bundle discount feature.
6. ReConvert Upsell
Best for: Post-purchase and checkout upsells with built-in recommendations
ReConvert started as a post-purchase upsell app and expanded into a full-funnel recommendation tool. It now covers product pages, cart, checkout, and thank-you pages. The drag-and-drop editor makes it easy to build recommendation flows without code, and it includes A/B testing to optimize which offers convert best.
With 2,855 reviews, it's one of the most widely used upsell apps on Shopify. The pricing scales with order volume, which keeps costs low for smaller stores but means your bill grows as you grow.
- Rating: 4.8/5 (2,855 reviews)
- Pricing: Free for dev stores. $4.99/month (up to 50 orders), $9.99 (up to 100), $19.99 (up to 200). 14-day trial.
- Best feature: Post-purchase upsell pages that show AI recommendations after checkout — a touchpoint most other apps miss
- Limitation: Usage-based pricing means costs increase as your store grows. A store processing 500 orders/month will pay more than the listed tiers.
7. Shopify Search & Discovery
Best for: Free, native recommendations without installing a third-party app
Shopify's own Search & Discovery app is free and built into the platform. It lets you customize search filters, add synonym groups for better search results, boost specific products, and set up product recommendations on detail pages.
The recommendations are basic compared to dedicated apps — you can assign complementary products manually or let Shopify's algorithm suggest them. There's no checkout or post-purchase placement, no A/B testing, and no audience segmentation.
- Rating: 3.3/5 (465 reviews)
- Pricing: Free
- Best feature: Zero cost, native integration, no impact on store speed
- Limitation: The 3.3 rating reflects real issues. Merchants report bugs, slow loading, and difficulty managing recommendations when products are archived. The recommendation algorithm is less sophisticated than dedicated apps.
Start here if you've never used product recommendations. It costs nothing and gives you a baseline to compare against paid alternatives.
Which Product Recommendation App Is Right for Your Store?
The right app depends on three things: where you want recommendations to appear, how sophisticated the AI needs to be, and what you can spend.
If you want simple "bought together" widgets on product pages: Frequently Bought Together CBB ($19.99/month flat) or Also Bought CBB ($19.99/month) are focused, reliable, and well-reviewed. They don't try to do everything — they do one thing well.
If you want recommendations everywhere — cart, checkout, post-purchase: Rebuy ($25-$538/month) or ReConvert ($4.99-$19.99/month) cover the full funnel. Rebuy is more powerful but significantly more expensive. ReConvert offers better value for stores under 200 orders/month.
If bundling is your strategy: Zoorix (free to $29.99/month) combines recommendations with mix-and-match bundles, BOGO deals, and volume discounts. It's the best option if you want to push multi-product bundles rather than standalone cross-sells.
If you want audience-level personalization: LimeSpot ($9.99-$50+/month) segments customers and serves different recommendations to different groups. Most useful for stores with repeat customers and diverse product catalogs.
If you're already using an order form app: Some order form tools include built-in recommendation features. EasySell, for example, includes an AI-powered product recommender in its Unlimited plan that suggests relevant products directly inside the order form — useful for COD stores that already use EasySell for checkout and don't want to add another app.
If budget is zero: Shopify Search & Discovery is free and native. It won't match the AI sophistication of paid apps, but it's a legitimate starting point.
How to Test a Recommendation App Before You Commit
Most recommendation apps offer free trials. Before committing, run a 2-week test with one specific metric in mind: does your average order value increase? Don't track installs, impressions, or widget clicks. Track dollars per order. If AOV doesn't move after two weeks of recommendations being live on your product pages, the app either needs reconfiguring or isn't the right fit for your catalog.
Install one app, set it up on your highest-traffic product pages, and compare AOV for the trial period against the two weeks before. That single number tells you more than any feature comparison ever will.
