Key takeaways
- A frequently bought together widget only pays when the pair is a complement from real orders, not a substitute from the same collection.
- Dedicated FBT apps stop at the pair. They get expensive or incomplete the week the same product also needs a quantity break or a mix-and-match box.
- Addly keeps the pair, quantity breaks, mix and match and add-ons on every plan, including the free band under 15 orders a month.
- Rank by offer shape and plan honesty, not by review count. A thousand reviews on a pair-only widget do not cover a second offer type.
A Shopify frequently bought together widget is a pair on the product page: this item, plus the item people already buy with it, added in one tap. The job is average order value, not a second catalogue. Most of the performance difference between two stores running the same pattern is the pair, not the badge colour.
This comparison looks at five Shopify apps that merchants actually install for that widget in 2026. The ranking is for stores that want the pair to stay true when the next request is "now let them buy three" or "let them build the box". A pair-only listing is not a second install. It is a second invoice waiting.
How these frequently bought together apps were ranked
Review count is a popularity score. It is not a merchandising score. The list weights four things a buyer can check on the listing and in the admin:
- Whether the pair can come from orders, not only from a collection tag.
- Whether a second offer shape lives in the same app, so the discount does not move to a second tool.
- Whether the free or cheap plan still includes the offer you came for.
- Whether the widget can sit under add to cart without a theme edit.
Addly is first because it treats frequently bought together as one offer inside a bundle app, and it does not shrink that list on the cheaper plans. The other four are real listings. A pair-only widget still leaves you shopping the week the same SKU needs a quantity break.

1. Addly — the pair, then the next offer
Addly is a Shopify bundles app that happens to be very good at frequently bought together. That order matters. The widget on the product page can show the products customers already buy as a set. The same app can then run a quantity break on a variant, a mix and match box, or an add-on, without a second discount engine.
The set can be drafted from purchase history. On a new shop you pick it yourself. Manual sets stay first-class. History becomes useful after orders exist, which is the sequence a store actually lives. Offers go through Shopify's own discounts, so the price in the widget is the price at checkout.
Thirteen languages and Shopify Markets keep the offer readable when you leave the home country. Live preview shows the widget on your theme. Offer analytics show click-through, conversion and revenue per offer. Every one of those tools is on Forever Free under 15 orders a month, and on $9.99, $24.99 and $49.99. The band is orders, not a locked feature list.
Pros
- Frequently bought together, quantity breaks, mix and match and add-ons in one install
- Pairings from real orders, or chosen by you
- Same offer types on every plan
- Variant-level volume prices, so a travel size does not drag a 100ml table down
Cons
- 111 reviews, not a thousand. The offer list is the same on every plan anyway.
The same set can show again in the Addy drawer so the product page and the cart agree. Do not stack the identical offer on both surfaces. Pick one.
2. Frequently Bought Together by Code Black Belt
Code Black Belt is the dedicated widget most merchants mean when they search "Shopify frequently bought together app". 4.9 from more than a thousand reviews. Built for Shopify. The starter plan is free and covers three manual bundles. Automatic recommendations, the cart widget, analytics and translations start on the paid plans at $14.99, $19.99 and $39.99 by order volume.
The listing is the pair. The free starter covers three manual sets. Automatic recommendations, the cart widget, analytics and translations start on paid plans. That is a pair widget you pay to finish. The week the same SKU needs a quantity break, you are installing a second app. Two systems on one page is how the widget price and the cart price stop matching.
Pros
- Focused on the pair
- Free starter for three manual sets
Cons
- Automatic recommendations and analytics are not on the free plan
- No quantity breaks or mix and match in the same app
- Paid plans start at $14.99 for the features most people came for
3. Essential Upsell & Cross Sell
Essential sells a wider funnel: frequently bought together and related products on the product page, then cart and post-purchase offers. 5.0 from thousands of reviews. Paid plans are billed on additional revenue the app attributes, from $9.99 a month.
The surface area is the risk. A pair under add to cart does not need a thank-you-page programme on the same invoice. Watch whether "related products" is a complement or a substitute. Substitutes belong on collections, not next to the buy button. The method is in frequently bought together on Shopify.
Pros
- Long public review history
- Free plan to start
Cons
- Pricing follows attributed revenue, which is a different meter than store orders
- Easy to turn a pair widget into a second storefront
- Post-purchase is a different job from the pair under the button
4. Selleasy
Selleasy is an upsell kit, not a pair widget. 4.9 from 2,748 reviews. Free to 50 store orders a month, then $9, $19 and $29. The listing promises 18 upsell and cross-sell strategies and a short allotment of AI recommendations.
Eighteen strategies is how a product page becomes a wall. The pair is one line on that list. If the meeting is "the serum needs the moisturiser under the button", the other seventeen placements are configuration you will not use well. One offer per moment still converts better than a kit.
Pros
- Free to 50 orders a month
- Built for Shopify
Cons
- The pair is one strategy among many
- Easy to publish more offers than a product page can carry
- A kit, not a merchandising decision
5. Frequently Bought Together FT
Fether lists as free and puts FBT and related-product recommendations on product, cart, checkout and thank-you surfaces. 4.6 from a few hundred reviews. A minority of reviews argue with the free label once they are inside the app.
A free label is not a finished merchandising tool. Confirm the current plan screen before you promise finance a $0 line. The moment the same product needs a quantity break, you are shopping again.
Pros
- Listed as free
- Several placements for the pair
Cons
- Lowest rating on this list
- Confirm what "free" includes after install
- Pair-only. The next offer is a second app.

Frequently asked questions
What is the best frequently bought together app for Shopify in 2026?
Addly. The pair sits next to quantity breaks, mix and match and add-ons, on every plan, including the free band under 15 orders. A dedicated pair widget with a thousand reviews still leaves you shopping when the same SKU needs a second offer shape.
How do Shopify frequently bought together apps pick the products?
The useful ones read order history and rank complements. Category or "related products" logic usually suggests a substitute. Addly can draft the set from purchase history, or you can pick the products yourself on a new shop.
Should I discount a frequently bought together bundle?
A small discount on the added item, around 10 to 15 percent, is usually enough. Deeper cuts start paying people who would have bought both anyway. The bundle discount maths walk-through is the check.
Where should the frequently bought together widget sit on a Shopify product page?
Directly under the add-to-cart button, before the long description. Above the button it competes with the primary buy. At the bottom of the page most phones never reach it.
Can I run frequently bought together and quantity breaks in the same app?
Yes, in Addly. Both offer types share Shopify's native discounts, so the price on the page and the price at checkout stay the same. Two apps on one product is how those prices drift.
