What a frequently bought together widget actually does
A frequently bought together block shows 2 or 3 products purchased together, with 1 combined add to cart button and usually a small bundle discount. It works because it moves the pairing decision from the shopper to the store: instead of hoping the customer browses for the matching item, the widget presents the pairing as the default. Amazon popularized the pattern, and it remains one of the highest-converting product page placements because the recommendation is grounded in real order history rather than generic bestsellers.

1. Libautech: Bundles & Upsell
Libautech: Bundles & Upsell shows frequently bought together recommendations with a 1-click combined purchase, and it holds a 5.0 rating with the Built for Shopify badge. The FBT block is 1 of 6 offer types in the app alongside fixed bundles, volume discounts, BOGO, free gifts, and cart drawer or popup upsells, so the pairs you set up can also power discounted bundles and cart offers.
Why consider it: FBT rarely stays your only offer type. Stores that start with FBT usually add quantity breaks or a cart upsell within months, and having them in the same app means shared targeting rules and 1 revenue report instead of a second subscription.
Best for: stores that want FBT as part of a complete AOV strategy.
Pricing: free plan available, see the App Store listing for current plan pricing.

2. Essential Upsell & Cross Sell
Essential holds a 5.0 rating from 2,171 reviews with a free plan, and its core product is exactly this widget: frequently bought together bundles with automatic discounts on product and cart pages.
Why consider it: a 5.0 rating at 2,000+ reviews is the strongest social proof among the dedicated FBT widgets.
Best for: stores that want a polished FBT widget and little else.
3. Selleasy (Logbase)
Selleasy (4.9, 2,446 reviews) leads on review volume. Its FBT bundles support both automatic recommendations and manual pairing, and the app adds cart page offers and post-purchase upsells. It is free to install with usage-based pricing.
Why consider it: zero fixed cost at low volume plus the option to expand into post-purchase later.
Best for: small stores that want to start free and scale.
4. Frequently Bought Together by Code Black Belt
Running since 2017, this is the app that brought Amazon-style FBT to Shopify. Its AI trains on your store's actual order history to surface pairings you would not have set manually, and it improves as order volume grows.
Why consider it: for large catalogs where manual pairing does not scale, trained AI pairing is the honest advantage of the specialist.
Best for: stores with 1,000+ SKUs and meaningful order history.
Pricing: see the App Store listing for current plans.
5. Wiser
Wiser goes beyond the FBT block into full-page personalized recommendations: recently viewed, top sellers, and AI picks across home, product, cart, and thank you pages.
Why consider it: if you want a recommendation layer across the whole site rather than a single widget, Wiser covers more surface area.
Best for: larger catalogs investing in site-wide personalization.
Pricing: see the App Store listing for current plans.
Setup advice: pairs beat algorithms at first
If your store has under roughly 500 orders of history, algorithmic pairing has too little data and will show weak matches. Start with manual pairs you know make sense, such as a device with its refill, consumable, or accessory, and attach a 5 to 10 percent bundle discount. Once order volume grows, let automatic recommendations take over the long tail while you keep manual control of your 10 best sellers.
FAQ
Does Shopify have a built-in frequently bought together feature?
Shopify themes can show generic related products, but true FBT with combined add to cart and a bundle discount requires an app.
Should FBT recommendations be automatic or manual?
Manual for your top sellers and low-history stores, automatic for long-tail products once you have order data. Most apps above support both.
Where should the FBT widget appear?
Below the add to cart button on the product page is the standard placement. Some apps, including Selleasy and Libautech: Bundles & Upsell, can also surface pairings in the cart.
Do FBT discounts stack with discount codes?
It depends on how the app applies the discount. Test a checkout with both before running a sale, since double discounting is the most common FBT configuration mistake.
