This guide reviews the best Shopify custom bundle apps: Easy Bundle Builder, BundleSuite, MBC Mix and Match, Easify Box Bundle Builder, Mix and Match Bundle Builder, FoxSell Bundle Builder, and Bundly.
A Shopify custom bundle app lets customers build their own bundle (mix-and-match, build-a-box, or gift box), which Shopify's native tools cannot do beyond fixed kits capped at 3 options and 100 variants.
The apps differ by use case: some focus on build-a-box and gift sets, some on bypassing the variant limit, some on design polish, and some on bundling plus discounts in one app.
Easy Bundle Builder is the best Shopify custom bundle app overall, covering every custom bundling format, the broadest discount engine, product-page and landing-page builders, AI bundle creation, and real-time inventory sync.
Custom bundling is one of the most effective ways to lift average order value on Shopify, but only if shoppers can actually build their own bundle the way they want. A Shopify custom bundle app gives customers a build-your-own-bundle, mix-and-match, or build-a-box experience that the native platform cannot, and it handles the discounting and inventory behind it.
This guide compares seven of the best Shopify custom bundle apps on features, custom bundle formats, discount options, design control, inventory handling, pricing, and verified reviews. Every app here is a true custom bundling app, not an upsell tool with a bundle label bolted on.
Detailed App Reviews: Top Shopify Custom Bundle Apps
1. Easy Bundle Builder (Best Overall)
Overview
Easy Bundle Builder is a Shopify custom bundle app that covers every way a store might let customers build a bundle, from build-your-own-bundle and mix-and-match to gift boxes, fixed product bundles with variant selection, and quantity breaks, all from one dashboard. It is built for stores that want a custom bundling app they will not outgrow, with a deeper discount engine, more design control, and better inventory handling than anything else on this list. Where Shopify's native bundles tool stops at fixed kits, Easy Bundle Builder gives shoppers a true custom bundle experience on a product page or a dedicated landing page.
Key Features
Build-Your-Own Bundle: customers assemble their own bundle from curated product pools, on a product page or a dedicated landing page.
Mix and Match: shoppers combine products across categories at a fixed or tiered bundle price.
Gift Box Builder: a dedicated build-a-box flow with personalization like gift messages and wrapping.
Fixed Bundles with Variant Selection: pre-curated bundles where customers still choose size or color.
Quantity Breaks: buy-more-save-more pricing surfaced on the product page, the builder, and the cart.
Broadest Discount Engine: percentage, fixed amount, fixed bundle price, Buy X Get Y, quantity breaks, and subscription recurring discounts.
Drag-and-Drop Design Builder: customize colors, fonts, and layouts so bundles match your theme without code.
AI Bundle Creation: a chat-based flow that sets up a bundle in minutes.
Real-Time Inventory Sync: component-level stock tracking so you never oversell a bundle.

Bundle-Level Analytics: per-bundle revenue, views, orders, AOV, and conversion rate, plus a Sources of Bundle Traffic breakdown showing where shoppers reached the bundle, and a per-product view of which items inside each bundle sell best.
Pricing
Free: up to $500/mo in bundle sales
Essential: $49/mo, up to $5,000/mo in bundle sales
Plus: $149/mo, up to $20,000/mo in bundle sales
Enterprise: $399/mo, up to $75,000/mo in bundle sales
Pros
Every custom bundle format in one app: build-your-own, mix and match, gift boxes, fixed, quantity breaks, and subscriptions.

Product-page and landing-page bundles: with full drag-and-drop design control.
Real-time component inventory sync: so bundles never oversell.
Functional free plan: with flat, predictable pricing as you scale.
4.9 stars from 920+ reviews: the strongest review profile of any app in this guide.
Fast setup with AI bundle creation: a chat-based flow builds your first bundle in minutes.
Expert 24/7 support: the team helps you decide what to bundle for your industry and how to structure it, so you are never stuck during setup.
Cons
Paid plans start higher than budget-only basic bundle apps but the free plan covers low-volume stores, and because it replaces several single-purpose apps, the all-in cost usually comes out lower.
Why Easy Bundle Builder is the Best Shopify Custom Bundle App
Most apps on this list do one or two kinds of custom bundling well. Easy Bundle Builder does all of them, then adds the discount engine and inventory handling to make them convert. Shoppers can build a box, mix and match, or add a quantity break, and the bundle still checks out as clean individual line items with accurate stock. Pair that with product-page and landing-page builders and per-bundle analytics, and it is the one custom bundle app that scales from a first bundle to a core revenue channel.

How to Choose the Right Shopify Custom Bundle App
Match the app to the bundle experience you want: Build-a-box and gift sets point to Easify or Easy Bundle Builder; mix-and-match points to Bundly or BundleSuite; everything in one app points to Easy Bundle Builder.
Check the variant ceiling: Shopify's native tool caps at 100 variants. If your assortment is larger, BundleSuite (2,048 variants) and FoxSell (infinite options) clear that wall.
Read the free-plan fine print: Some free plans are development-only (BundleSuite, Mix and Match Bundle Builder) or capped (MBC at 10 orders, Easify and FoxSell revenue-gated). Easy Bundle Builder's free plan covers up to $500 a month in bundle sales.
Decide how much discounting you need: Easy Bundle Builder and MBC build discounts into the bundle, while design-first apps like Bundly lean on bundle pricing rather than codes.
Factor in the pricing model: Flat pricing (Mix and Match Bundle Builder at $14.99, Easy Bundle Builder tiers) keeps costs predictable, while revenue-capped plans (BundleSuite, Easify, FoxSell) rise as your bundle sales grow.
Can You Create Custom Bundles Without an App on Shopify?
Partially. Shopify's free first-party Bundles app creates fixed bundles and multipacks, and it works on all plans with no Shopify Plus requirement. Discounts apply to native bundles, allocated across the component products.
What you cannot do without an app is let customers build their own bundle. Native bundles are fixed, merchant-defined kits capped at 3 options and 100 variants, with no customer-facing build-a-box or mix-and-match flow. Shopify's documentation is explicit that customized, mix-and-match bundles require a custom app built on the Cart Transform Function API, which is a developer building block rather than a ready-to-use feature. That is why stores that want real custom bundling reach for a dedicated custom bundle app: it provides the build-your-own interface out of the box, removes the variant ceiling, keeps component inventory in sync, and adds tiered or volume discounts without code.
Conclusion
In this guide, we examined some of the best Shopify custom bundle apps, including Easy Bundle Builder, BundleSuite, MBC Mix and Match, Easify Box Bundle Builder, Mix and Match Bundle Builder, FoxSell Bundle Builder, and Bundly. We evaluated them on custom bundle formats, discount options, design control, inventory handling, pricing, and reviews.
Overall, Easy Bundle Builder stands out as the most well-rounded Shopify custom bundle app, covering every custom bundling format with the broadest discount engine and the most design control. BundleSuite is the pick for bypassing the variant limit, Easify for gift-box experiences, and Bundly for the most premium-looking builder. Whichever you choose, pairing custom bundles with broader work to increase your average order value is what turns bundling into a real revenue channel.
A good way to approach this is to shortlist a few apps, sign up for the trial period, and see what works best for your store. All the best!
