Best product bundle apps for Shopify: This guide compares Easy Bundle Builder, Pumper Bundles, Fast Bundle, Bundler, Kaching Bundles, Zoorix, BundleSuite, Koala Bundles, and Rapid Bundles on bundle types, checkout behavior, subscription support, discount stacking, and pricing.
Best product bundle app for Shopify overall: Easy Bundle Builder covers every bundle format (BYOB, mix and match, gift boxes, fixed bundles, quantity breaks, and subscription bundles) in one app, and passes bundle items to checkout as separate line items for clean fulfillment.
Best free product bundle app for Shopify: Bundler's free plan has no revenue or order cap, which makes it the easiest way to start bundling at zero cost.
Best budget product bundle app for quantity breaks: Pumper Bundles is a lightweight pick for product-page quantity breaks, with paid plans from $9.99/month.
How to choose: Match the app to the bundle types you actually sell first, then check checkout behavior and subscription support before comparing price.
I spent a few weeks going through every major Shopify product bundle app on the App Store: reading the listings and help docs, comparing bundle types and pricing, and working through the 1-star reviews to see where each one breaks. Honest takeaway: most product bundle apps for Shopify do one or two formats well and struggle the moment you ask for more.
Bundling is worth getting right. Oral care brand Hismile says over 80% of its orders are bundled products, with bundles driving a 4x increase in average cart size[1]. Across home, beauty, and wellness, bundled SKUs now make up to 25% of revenue for top-performing brands[2], and peer-reviewed research shows that shoppers who choose bundles end up buying more overall[3].
Shopify product bundle apps drive average order value by letting stores sell pre-curated bundles, build-your-own-bundle (BYOB) flows, mix-and-match boxes, gift boxes, quantity breaks, and subscription bundles, formats the native Shopify Bundles app does not cover. Checkout behavior also matters more than it used to: Shopify retired its Scripts engine on June 30, 2026, so bundle apps now need to run on Shopify's modern APIs, such as the Cart Transformation API or Shopify Functions, to keep working correctly at checkout.
In this guide, I've narrowed my shortlist down to the best Shopify product bundle apps and compared them on bundle types, checkout behavior, subscription support, discount settings, and pricing. Every app here has a free plan or a trial, so you can test before you commit. Let's dive in.

I judged every app on the same seven criteria, using each app's live Shopify App Store listing, its help documentation, and its most recent reviews especially the 1-star and 2-star reviews:
Before picking an app, it helps to know which bundle types you actually need, because most apps only cover a few. Here are the main ones:
If you're wondering what the best product bundle app for Shopify is, the answer depends on your store's goals. My top pick this year is Easy Bundle Builder, because it covers every bundle format in one app. But there are good options for every budget and use case. Let's take a look.
Easy Bundle Builder is a Shopify product bundle app that covers every bundle format in one place: BYOB and mix-and-match flows, pre-curated product bundles, gift box builders, quantity breaks, subscription-compatible bundles, and tiered volume discounts. You can set up a bundle by describing it to the AI builder, start from a ready-made template, or build it manually, and if you want something unique, Signature Bundles lets you send your design and have the team build it for you. Built-in Bundle Recommendations also suggest which products to bundle, how to price them, and where to place them. It's the one I'd pick if you want a single app for your whole bundling setup instead of stitching two or three together.
Easy Bundle Builder covers every bundle format a Shopify store typically needs: build-your-own-bundle flows with multi-step UX, pre-curated product bundles, gift box builders with personalization, quantity breaks and tiered volume discounts built into the bundle widget, and subscription-compatible bundles that work alongside Shopify Subscriptions, Recharge, Loop, and Appstle. The Landing Page Bundle Builder gives stores a dedicated full-page bundling experience, while the Product Page Bundle Builder embeds bundles directly on product pages with on-brand design controls. Bundle items reach checkout as individual line items, so fulfillment, inventory, and your other apps keep working cleanly. For partners, a developer-friendly SDK and API make fully custom bundle experiences possible. The app has been used by 20,000+ Shopify merchants.

Shopify stores on any plan that want one app for every bundle format, especially brands running gift boxes, BYOB, quantity break or subscription bundles.

Pumper Bundles Quantity Breaks is a Shopify product bundle app built around quantity breaks, with fixed bundles, multipacks, BOGO, and free gifts layered on top. Its widget sits inside your existing product template, so it's a quick way to add volume offers to product pages without committing to a heavier all-in-one bundle builder.

Stores that mainly want simple quantity breaks and volume discounts on product pages at a low monthly cost.
4.9 stars (3,400+ reviews), Shopify App Store
Fast Bundle is a Shopify product bundle app with one of the widest ranges of bundle types: fixed bundles, multipacks, mix and match, variant bundles, build-a-box, gift boxes, subscription boxes, wholesale, AI-powered Frequently Bought Together, and POS bundles. Worth knowing: it was temporarily removed from the Shopify App Store in July 2026 after a security incident and has been fully back since August, with the developer stating that no customer or store data was accessed.

Stores that want broad bundle-type coverage, AI bundle imagery, and bundles in Shopify POS.
5.0 stars (3,400+ reviews), Shopify App Store

Zoorix: Bundles & Cross Sell is a Shopify product bundle app that pairs bundles with AI cross-sell, so offers show up on product pages and in the cart drawer. It covers fixed bundles (up to 8 items), mix and match, build a box, volume discounts, and BOGO, and every plan includes every feature.

Stores that want bundles and cart-drawer cross-sells in one app on a small budget.
4.9 stars (380+ reviews), Shopify App Store
BundleSuite Bundle Builder is a Shopify product bundle app positioned as an all-in-one bundle builder, with templates for BYOB, mix and match, box builders, fixed bundles, multi-step bundles, and Infinite Options bundles that get around Shopify's 100-variant limit. Bundles run on Shopify's Cart Transform, so individual SKUs appear on orders for fulfillment.

Stores with very high variant counts, or anyone who needs to bypass Shopify's 100-variant cap.

Rapid Bundles & Upsell app (formerly Rapi Bundles) is a Shopify product bundle app that combines fixed, combo, mix and match, and variant bundles with a box builder and post-purchase upsell funnels. Unlike most apps here, it has a genuinely free plan for live stores.
Beginners who want a free plan with bundles and post-purchase upsells, with room to grow into AI features.
5.0 stars (1,500+ reviews), Shopify App Store
Yes, for fixed bundles and multipacks. Shopify launched its own free first-party app, Shopify Bundles, which lets stores create static bundles directly from the Shopify admin. It supports component-level inventory tracking and is free on every Shopify plan from Basic upward. For more advanced bundle formats, a dedicated app fills the gap.
If your store relies on gifting, cosmetics kits, food and beverage variety packs, BYOB curation, subscription bundles, or volume discounts, a dedicated bundle app is the practical option. The apps in this guide cover those use cases.
In this guide, I compared the best Shopify product bundle apps: Easy Bundle Builder, Pumper Bundles, Fast Bundle, Bundler, Kaching Bundles, Zoorix, BundleSuite, Koala Bundles, and Rapid Bundles. I evaluated them on bundle-format breadth, checkout behavior, subscription support, discount stacking, pricing, and recent reviews.
Overall, Easy Bundle Builder stands out as the most well-rounded Shopify product bundle app, covering BYOB, mix and match, pre-curated bundles, quantity breaks, gift boxes, and subscription bundles in a single app, with Landing Page and Product Page Bundle Builders, custom templates, and Signature Bundles if you want the team to build it for you. For budget-conscious stores, Bundler offers a free plan with no revenue cap. For simple product-page quantity breaks, Pumper Bundles is a low-cost pick, and for bundles plus cart-drawer cross-sell, Zoorix is a good fit.
The best approach is to shortlist two or three apps, start the free trials, and see which one fits your store. All the best!

FAQs on Best Product Bundle Apps on Shopify
Easy Bundle Builder is the best product bundle app for Shopify overall. It covers BYOB, mix and match, pre-curated bundles, gift boxes, quantity breaks, and subscription bundles in one app, with Landing Page and Product Page Bundle Builders, custom templates, and bundle items that reach checkout as individual line items. For a free option, Bundler's free plan has no revenue cap, and for simple product-page quantity breaks, Pumper Bundles is a low-cost pick.
Most product bundle apps for Shopify have a free plan or a free trial, with paid plans typically starting between $7.99 and $29 per month. Bundler and Rapid Bundles offer free plans for live stores, while Fast Bundle, Kaching, BundleSuite, and Koala are free only on development stores. Many apps price by bundle sales or generated revenue, so costs rise as bundles earn more. Easy Bundle Builder runs from free up to $99 per month for up to $10,000 in monthly bundle sales.
Some do. Easy Bundle Builder works with Shopify Subscriptions, Recharge, Loop, and Appstle. Fast Bundle supports several subscription apps on paid plans, Bundler integrates with Seal Subscriptions, Kaching works with its own subscriptions app and Loop, and Rapid Bundles uses its own Rapid Subscription app. BundleSuite lists subscription bundles as coming soon. Shopify's native Bundles app cannot be sold with subscriptions at all.
Your 3PL reads orders from Shopify, so what matters is how the bundle appears on the order. Apps that pass bundle items as individual line items with their own SKUs, such as Easy Bundle Builder, BundleSuite, and Fast Bundle in its Cart Transform mode, let your warehouse pick each product correctly. Apps that only apply a discount to existing products also keep separate SKUs. If an app sends a single bundle SKU instead, your 3PL needs to know which components are inside it.
When bundle items are recorded as individual products on the order, returns follow Shopify's normal flow, so you can refund and restock the specific items that come back instead of one bundle SKU. BundleSuite supports item-level refunds with the bundle discount spread across items, while Bundler asks merchants to subtract the bundle discount by hand on partial refunds. Decide up front whether you accept full-bundle returns only or individual item returns, and give your warehouse clear restocking rules.
Often, but with limits. Shopify will not stack two product discounts on the same item, so a bundle discount and a product-level promo code on the same product usually means only the larger one applies. Most product bundle apps for Shopify let bundle discounts combine with order-level codes and free shipping when combinations are enabled in both the app and Shopify. Easy Bundle Builder includes a setting to allow or block promo code stacking on top of bundle discounts.
