Key takeaways
- A frequently bought together (FBT) widget pairs a product with its natural companions and lets the shopper add them in one click, the single highest-leverage way to lift average order value on the product page.
- We make Libautech Bundles & Upsell and rank it first, because it runs FBT alongside quantity breaks, cart and post-purchase offers in one app. Weigh that we have a commercial interest.
- For a pure, single-purpose FBT widget with the deepest track record, Frequently Bought Together by Code Black Belt is the specialist, and we say so.
- This is our 2025 edition, kept for reference. The current 2026 ranking has refreshed picks and an interactive calculator.

What a frequently bought together app does
A frequently bought together widget shows, on the product page, the items customers commonly buy alongside the one they are viewing, with a combined add to cart. Amazon built an estimated third of its revenue on this mechanic, and Shopify does not include it natively at that level. The value is friction: a relevant companion the shopper can accept in one click gets accepted, while a recommendation that opens a new page and restarts the decision mostly does not.
In 2025 the category split into a few jobs: single-purpose FBT widgets, AI-powered recommendation engines, free-entry all-rounders, and apps that fold FBT into a broader bundle or upsell funnel. The right pick depends on which of those you need.
Who needs an FBT app
An FBT app earns its keep when you have complements to pair. If your catalog is single hero products with nothing that goes with them, it is premature. Match yourself to a row before installing.
| Your store | Best pick | Why |
|---|---|---|
| Want FBT plus the whole funnel | An all-in-one upsell app | One app for FBT, cart and post-purchase beats stacking three. |
| Only want the FBT block | A single-purpose widget | Simple setup and predictable behavior if cart and post-purchase are handled elsewhere. |
| Tight budget, want proof first | A free plan or free-to-install app | Prove FBT earns before paying a monthly fee. |
| Large catalog, learned pairings | An AI recommendation engine | Order-history pairing scales where manual curation cannot. |
How we ranked these, and a word on bias
The disclosure first. We make Libautech Bundles & Upsell, and we rank it first, so read this with that in mind. We rank it first because it runs FBT alongside quantity breaks, cart and post-purchase offers in one app, which suits a store that wants more than the widget. On the FBT widget itself the specialists are strong, and where our app is behind is public proof: it is the newest here at 35 reviews, while Frequently Bought Together by Code Black Belt has more than 1,000. We name the better fit for each job in the which to choose section. Ratings are read from the live App Store; this 2025 edition is kept for reference, and the 2026 edition carries the current numbers.

The apps, ranked
1. Libautech Bundles & Upsell
Bundles & Upsell (our app, 4.9 across 35 reviews, Built for Shopify) builds frequently bought together sets with a combined one-click add, and runs them alongside quantity breaks, product add-ons, cart offers and post-purchase, all from one dashboard with per-offer revenue tracking. Setup is AI-assisted: you describe the offer and Claude drafts it.
Strengths: FBT is one part of a complete upsell app, so you get bundling plus the rest of the funnel on one bill rather than stacking apps that each inject their own scripts.
Watch-outs: we will be straight, it has the smallest review base here at 35, because it is the newest app on this list. For a pure FBT widget with more public proof, the specialists below have longer track records.
Best for: stores that want FBT plus the whole upsell funnel in one app. From $9.99/mo.
2. Frequently Bought Together by Code Black Belt
Running since 2017 (4.9 across more than 1,000 reviews, Built for Shopify), this app does exactly one thing: an Amazon-style frequently bought together block powered by AI analysis of your order history.
Strengths: extreme focus means simple setup, predictable behavior and a long, well-reviewed track record, with automatic pairings learned from real orders.
Watch-outs: it is the FBT block and nothing more, so you will need other tools for cart and post-purchase.
Best for: stores that already handle cart and post-purchase elsewhere and want the most-proven FBT widget. From $14.99/mo, free plan available.
3. Also Bought by Code Black Belt
Also Bought (4.7 across 312 reviews, Built for Shopify), from the same developer as Frequently Bought Together, renders an Amazon-style "customers who bought this also bought" carousel using unlimited order history for its recommendations.
Strengths: fast, lightweight recommendation carousel with a proven AI engine behind it, a good complement to a combined-add FBT block.
Watch-outs: it is a recommendation carousel rather than a combined one-click bundle, so it drives discovery more than a single-click AOV lift, and it overlaps with the FBT widget if you run both.
Best for: stores wanting an also-bought discovery carousel alongside or instead of a combined FBT block. From $9.99/mo.
4. Essential Upsell & Cross Sell
Essential (5.0 across more than 2,200 reviews, Built for Shopify) pairs a genuine free plan with the highest rating on this list, covering FBT on the product page plus cart and post-purchase upsells.
Strengths: the best free starting point here, a near-perfect rating, and full-journey coverage for a store that wants breadth without paying upfront.
Watch-outs: the free tier is capped, so heavy use pushes you to a paid plan as you grow.
Best for: stores that want the most-proven free plan with room to grow. Free plan, then from $9.99/mo.
5. Selleasy
Selleasy (4.9 across roughly 2,486 reviews, Built for Shopify) covers frequently bought together, product add-ons and in-cart cross-sells, and it is free to install, so a growing store runs real FBT before paying a monthly fee.
Strengths: excellent value and a deep, positive review base across the core upsell surfaces, with FBT as one of several placements.
Watch-outs: the AI suggests products but you build the offers, and the interface is functional rather than polished.
Best for: value-focused stores wanting a proven all-rounder. Free to install, paid plans from $9/mo.
6. Fly Upsell & Cross Sell
Fly Upsell & Cross Sell (4.9 across 579 reviews), formerly Fly Frequently Bought Together, runs FBT and upsell offers across multiple placements, from the product page to the cart.
Strengths: flexible placement of FBT and upsell offers across the journey, with a solid rating and a free plan for testing.
Watch-outs: a smaller review base than the category leaders, and the rebrand from a pure FBT widget to a broader upsell tool means the FBT block is one of several features.
Best for: stores wanting FBT plus upsell across several placements from one app. Free plan, then paid tiers.
Which FBT app to choose
Best all-in-one, FBT plus the funnel: Libautech Bundles & Upsell, our app.
Best pure, most-proven widget: Frequently Bought Together by Code Black Belt.
Best free plan: Essential Upsell & Cross Sell, a 5.0 across thousands.
Best free-to-install all-rounder: Selleasy.
Which frequently bought together app is right for you?
Pick what matters most and we will point you to the best fit. Often it is not ours, and we say so.
What an FBT offer is worth
Put in your monthly orders, the share of shoppers who accept the FBT offer, and what the added item costs, to size the extra revenue an FBT program adds.
Extra revenue a month
$1,000
Extra revenue a year
$12,000
That is about 40 accepted offers a month at $25 each. It is gross added revenue, before any bundle discount: a 10 percent FBT discount trims it by roughly that much, and the figure only holds if the offer actually created the bigger order rather than discounting one that would have happened anyway. You can run FBT free from Bundles & Upsell.
Common FBT mistakes
Pairing a random bestseller. An FBT set that ignores the viewed product reads as noise. Pairings should come from order history or a deliberate rule.
Sending the shopper to a new page. An FBT offer that restarts the decision elsewhere mostly fails. Keep the add one click, in place, with a combined add to cart.
Offering too many items. Two or three companions convert better than a long list; acceptance drops as choice becomes a comparison task.
Running two apps that both render FBT. Two FBT widgets on the same product page fight each other and add duplicate scripts. Pick one.
