Best Shopify bundle & frequently-bought-together app in 2026
A bundle app does one job well: it lifts units per order at the product page, before the customer ever reaches the cart. That is a different move from a post-purchase or in-cart upsell, and it is the lowest-friction one, because you are shaping what goes into the cart rather than interrupting a checkout in progress. "Bundle app" covers three distinct mechanics that get lumped together: the Amazon-style frequently bought together (FBT) widget that suggests a curated set on the product page, the volume or quantity break that discounts "buy 3, save 10%," and the fixed bundle or multipack that sells a pre-built set as one buyable unit. Below we rank the top product-page bundle apps from live App Store ratings (July 2026), match each to the bundle type it does best, and do two things the vendor roundups will not: we refuse to quote the unverifiable "+X% AOV" figures, and we flag the one structural advantage bundles hold this year. We did not hands-on test every app, and we say so.
Best value / widest placement: Selleasy (4.9, from $9/mo) - FBT plus the widest placement coverage for the price.
Best volume breaks / fixed bundles: Wide Bundles (4.9) - the quantity-break and bundle specialist.
Best pure recommendations, flat price: Also Bought by Code Black Belt (4.7, flat $19.99/mo).
Free baseline: Shopify's own native Bundles app (free) creates basic fixed bundles and multipacks from the admin.
The honest edge: these are product-page tools that never touched checkout, so they are unaffected by the checkout-extensibility deprecation that is reshaping the rest of the upsell category. That is a genuine, lower-risk advantage.
First, which kind of bundle do you actually want?
"Bundle" is three different mechanics, and picking the mechanic settles most of the choice before you compare brands. This is the frame the vendor listicles skip. Match your goal to the bundle type, and the shortlist narrows itself.
| Bundle type | What it does | Best for | Top picks |
|---|---|---|---|
| Frequently bought together (FBT) | Amazon-style "add these 3 together" set on the product page | Complementary attach, curated sets | Frequently Bought Together, Selleasy |
| Volume / quantity break | Tiered discount for buying more of one item ("buy 3, save 10%") | Consumables, refills, units per order | Wide Bundles |
| Fixed bundle / multipack | Pre-built set sold as one buyable product with its own inventory | Starter kits, gift sets, curated packs | Wide Bundles, Shopify Bundles (native) |
| Pure recommendations | "Customers also bought" cross-sell rows, no forced discount | Discovery, catalog attach | Also Bought, Selleasy |
The shortcut: if you sell products that pair naturally (a camera and its case), you want frequently bought together (Frequently Bought Together, or Selleasy for wider coverage). If you sell consumables people stock up on, you want volume breaks (Wide Bundles). If you want a curated kit as its own SKU, that is a fixed bundle (Wide Bundles, or the free native app for something basic). Pick the mechanic first and the "which app" question mostly answers itself.
The quiet advantage: bundles never touched checkout
Here is the part the rest of the upsell category cannot claim in 2026. Shopify retired the old checkout.liquid customization: the deadline to upgrade thank-you and order-status pages was August 28, 2025, and from January 2026 Shopify began automatic upgrades that strip any customization still using the old additional scripts or script-tag apps (Shopify checkout upgrade guide). Any app that fires an offer inside or after checkout now has to be rebuilt on checkout UI extensions, and native in-checkout upsell stays a Shopify Plus feature. Product-page bundle and FBT apps sit entirely on the product page. They shape the cart before checkout and never inject anything into the checkout surface, so the deprecation does not affect them at all. That is a real, lower-risk reason to lean on a bundle app: it is the one upsell placement Shopify's checkout migration cannot break. Our placement-ranked upsell roundup covers the apps that do have to worry about it.
Bundle and frequently-bought-together apps live on the product page. They never touched checkout, so the checkout-extensibility deprecation cannot break them. That is the lowest-risk upsell you can install in 2026.MerchantStack ranking method
The full field, at a glance
Live rating and review volume, bundle type, where it fires, entry price, whether the checkout-extensibility change touches it, and who funds it. Note the "CEX-affected?" column: for pure product-page tools the answer is a clean no, which is the whole point of choosing one.
| App | Bundle type | Placement | Entry price | CEX-affected? | Funding |
|---|---|---|---|---|---|
| Frequently Bought Together | Amazon-style FBT | Product page | $14.99/mo | No (widget, not checkout) | bootstrapped |
| Selleasy | FBT + bundles | Product + cart + checkout + thank-you | $9/mo | Only its Plus checkout tier | bootstrapped |
| Wide Bundles | Volume break / fixed bundle | Product page | $14.99/mo | No (product-page only) | bootstrapped |
| Also Bought | Pure recommendations | Product + cart | $19.99/mo (flat) | No (recommendation rows) | bootstrapped |
| Shopify Bundles (native) | Fixed bundle / multipack | Product page / admin | Free | No (first-party) | Shopify native |
The top picks, by bundle type
Do not overlook the free baseline. Shopify ships its own native Bundles app at no cost, which creates fixed bundles and multipacks straight from the admin with real-time inventory. It is deliberately basic (limited options per bundle, no FBT algorithm, no volume-break tiers), so it will not replace the specialists above for anything sophisticated, but if all you need is a simple pre-built set as its own buyable unit, start free and only pay for an app when you outgrow it.
The three things that actually decide it
Frequently asked questions
What is the best Shopify bundle app? It depends on the bundle type. For Amazon-style frequently bought together, Frequently Bought Together by Code Black Belt is the benchmark. For the widest coverage at the lowest price, Selleasy. For volume breaks and fixed bundles, Wide Bundles. See the bundle-type router above.
Is there a free bundle app? Yes. Shopify's own native Bundles app is free and creates basic fixed bundles and multipacks from the admin. It is limited, but a fine starting point before you pay for a specialist. Frequently Bought Together also has a small free tier for a few manual bundles.
Does the checkout-extensibility change affect bundle apps? No, and that is their advantage. Bundle and frequently-bought-together apps fire on the product page and shape the cart before checkout, so they never used checkout.liquid and are unaffected by Shopify's checkout upgrade. See our placement guide for the placements that are affected.
Do bundle apps really increase average order value? They can lift units per order, but the advertised percentages are unverified vendor marketing drawn from best-case customers. Install one, measure your own result, and keep it only if it earns its keep.
Bottom line
Choose the bundle mechanic, not the marketing. Pair complementary products with Frequently Bought Together, stretch a small budget across every placement with Selleasy, discount volume with Wide Bundles, and run simple cross-sell rows with Also Bought. If you only need a basic fixed set, start with Shopify's free native Bundles app. Whichever you pick, remember the structural edge that makes bundles worth prioritizing this year: they live on the product page, they never touched checkout, and the checkout-extensibility deprecation reshaping the rest of the upsell category cannot break them. That makes a bundle app the lowest-risk unit-lifting move on Shopify in 2026. For the placements that do carry migration risk, see our full upsell roundup and cart upsell picks.
