5 Best BYOB Shopify Apps for Build-Your-Own Bundles (2026)

The best BYOB Shopify apps don't all work the same way. Some let customers pick products from a simple grid, while others guide them through choosing items, selecting packaging, and adding personalized details. Their pricing models, selection rules, and customization options also differ enough to make choosing the wrong app an expensive decision later.

This comparison covers five apps: PushBundle, Easy Bundles, Kitenzo, Easify Box Bundle Builder, and MBC Bundle Builder. We'll look at their customer experience, product-selection controls, discount capabilities, pricing, and limitations so you can narrow down your options before installing.

Short Answer: PushBundle is a practical option for launching a guided build-a-box experience with predictable monthly pricing. Easy Bundles suits stores needing subscription bundles and more advanced workflows. Kitenzo offers extensive design and headless customization, Easify supports personalized gift and subscription boxes, and MBC provides straightforward single-step and multi-step bundles.

These are fit-based recommendations, not a claim that one app is best for every store.

TL;DR

• PushBundle: Guided multi-step BYOB with product choices, gift boxes, and personalization. The required Growth plan costs $14/month.

• Easy Bundles: Suitable for advanced workflows, subscription bundles, and customization. Multi-step building starts at $29/month.

• Kitenzo: Offers full-page builders, selection rules, and headless development tools, with a 1.5% per-bundle-transaction fee.

• Easify Box Bundle Builder: Supports personalized boxes and subscription integrations. Its free plan covers up to $500 in monthly box revenue.

• MBC Bundle Builder: Provides single-step and multi-step bundle layouts for $19.99/month on regular live stores.

Best BYOB Shopify Apps at a Glance

A build-your-own-bundle (BYOB) lets customers select products from an assortment to create a personalized bundle. Build-a-box is a common format that organizes those choices into a box-style or guided experience.

Not every build-your-own bundle needs a visual box. A pick-any-four snack assortment is also BYOB, even if it uses a simple product grid.

The comparison below focuses on the differences that matter when choosing a Shopify build a box app.

Pricing is in USD and was checked against Shopify App Store listings on October 22, 2026. Features, eligibility conditions, and billing can change.

All five apps currently display Shopify's Built for Shopify certification. Since every option shares that designation, it shouldn't be the deciding factor between them.

Instead, look closely at how customers make selections, what happens when they reach quantity limits, which features require paid plans, and whether the pricing fits your expected bundle sales.

How We Evaluated These BYOB Apps

We compared the apps using five considerations: customer-facing bundle structure, product-selection restrictions, discount and personalization options, pricing and plan eligibility, and the type of merchant each app is suited to.

Feature and pricing information was checked against official Shopify App Store listings and available product documentation. The PushBundle workflow was also reviewed through its product demonstration. This is a documentation-based comparison, not a claim that all five apps underwent the same independent storefront test.

The 5 Best BYOB Shopify Apps

1. PushBundle

2. Easy Bundle Builder

3. Kitenzo

4. Easify Box Bundle Builder

5. MBC Bundle Builder

App#1 PushBundle

Best for Guided Build-a-Box Experiences

PushBundle offers build-your-own-box, mix-and-match, volume, and cross-sell bundles in one Shopify app.

Its newer Build Your Own Box feature is particularly relevant for merchants who want customers to complete a guided shopping journey instead of selecting everything from one product grid.

Merchants can create multiple steps inside the Shopify admin without coding. Each step can handle a different part of the box-building experience, including product selection, packaging, gift cards, and personalized information.

For example, a skincare merchant could create a self-care gift box where customers first select products from a collection, choose between red, gold, and ribbon gift boxes, and then enter a personalized message.

The builder includes a live preview, configurable step titles, product or collection selection, required form fields, and options for selection restrictions and discounts. Merchants can also adjust the order of steps to fit the intended shopping experience.

What Stands Out

The distinction is the guided structure. Product choices, packaging, and personalization can be presented as separate stages, helping merchants create a more organized gifting experience.

PushBundle also offers multi-product mix-and-match bundles for customers who simply need to fill a predefined pack.

A real example is Mr Mushroom's build-your-own snack packs. The store uses PushBundle's multi-product mix-and-match feature to let shoppers select their own 4-packs or 6-packs, with different discounts for each size.

That example demonstrates mix-and-match BYOB rather than the newer multi-step Build Your Own Box format. Both serve customer-selected assortments, but the shopping flows differ.

What to Consider Before Installing

PushBundle's free Starter plan covers volume bundles. Build-a-Box, Mix & Match, and multi-step BYOB require the $14/month Growth plan, which includes a 14-day free trial.

Best for: Shopify merchants launching guided gift boxes, personalized product assortments, or multi-step bundles who prefer predictable monthly pricing.

Pricing: Free Starter plan for volume bundles; Growth at $14/month for BYOB.

App#2 Easy Bundles: Bundle Builder

Best for Advanced Bundle Workflows

Easy Bundles: Bundle Builder supports fixed bundles, mix-and-match assortments, build-a-box offers, and subscription bundles.

Its single-step and multi-step builders allow merchants to organize product selections into different shopping experiences.

For a gift-box store, that could mean letting customers choose their favorite items, add extras, and move through a guided selection process. The app also advertises independent bundle landing-page templates, product filtering, multilingual support, and developer tools for custom implementations.

The important distinction is how those capabilities are distributed across its plans.

What stands out

Easy Bundles is worth considering when a store needs more than a standalone gift box.

The Essential plan includes single-step and multi-step builders, independent landing-page templates, and search and filtering tools. The Growth plan adds advanced discounting, custom personalization fields, bundle add-ons, free gifts, and subscription bundles.

That makes Growth more relevant for merchants offering recurring gift boxes or requiring personalized fields alongside complex discount rules.

What to consider before installing

Easy Bundles has a free tier, but it doesn't include the paid multi-step builder capabilities.

Its Essential plan costs $29/month and has a limit of $3,000 in monthly bundle sales. Growth costs $49/month with a $5,000 bundle-sales limit, while the $99/month Scale plan includes advanced analytics and a $10,000 limit.

The free and Essential tiers also have eligibility restrictions for Shopify Advanced and Plus stores.

Subscription compatibility should be confirmed for your specific subscription app and checkout setup.

Best for: Merchants who need advanced discounts, custom fields, subscription bundles, or multiple bundle experiences.

Pricing: Free tier available; Essential $29/month; Growth $49/month; Scale $99/month.

App#3 Kitenzo

Best for Customizable Bundle Experiences

Kitenzo lets Shopify merchants create build-your-own bundles, personalized gift boxes, and custom product assortments using a visual builder.

Merchants can define available products, configure selection quantities, set pricing rules, and create step-based bundle experiences.

The app also supports full-page bundle builders and embedded experiences, providing more than one way to introduce bundles into a storefront.

What stands out

Kitenzo offers configuration options for brands that want greater control over the bundle-building interface.

Its documented capabilities include product limits, required selections, validation rules, fixed bundle pricing, percentage discounts, volume discounts, and free-gift conditions.

For businesses using a custom storefront, Kitenzo also advertises a React SDK and headless API.

That makes it relevant for stores whose bundle builder is a prominent part of the shopping experience, particularly when developers need to integrate it with a customized frontend.

What to consider before installing

Kitenzo's current Performance plan is free to install, but it charges 1.5% per bundle transaction.

This differs from apps charging a fixed monthly subscription.

For example, a merchant processing $2,000 in chargeable bundle transactions would pay approximately $30 at that percentage. At $10,000, the fee would be $150.

These are illustrative calculations, not quoted invoices. Actual charges depend on the app's billing terms and transaction values.

For stores processing higher bundle revenue, it's important to compare this model against fixed-fee alternatives. Stores with lower transaction volume may prefer avoiding a recurring subscription.

Best for: Brands needing advanced selection rules, extensive storefront customization, or headless bundle integration.

Pricing: Free to install; 1.5% per bundle transaction.

App#4 Easify Box Bundle Builder

Best for Personalized Gift and Subscription Boxes

Easify Box Bundle Builder supports customized gift boxes, mix-and-match bundles, and single-step or multi-step box-building experiences.

The app offers more than 30 templates alongside a visual editor for configuring bundle layouts, headings, banners, buttons, and colors.

Merchants can also configure product-selection rules, discounts, and personalization fields.

What stands out

Easify provides several ways to collect additional customer information during bundle creation.

Its advertised custom fields include gift messages, gift notes, date and time inputs, and file uploads.

For example, a merchant selling birthday gift boxes could allow customers to select products and provide gifting details as part of the same buying process.

Easify also advertises subscription-box support through integrations with subscription apps. This makes it worth evaluating for businesses that sell recurring assortments, provided their chosen subscription setup is compatible.

What to consider before installing

Easify's free Start plan includes its listed box-building features, but remains free only while monthly box revenue is within $500.

Once revenue exceeds that threshold, merchants need to move to a paid tier.

The Grow plan starts at $29/month for stores with less than $5,000 in monthly box revenue. Scale costs $99/month for less than $25,000.

This makes the app's billing closely connected to how much revenue the box offers generate.

The model may suit merchants testing their first custom box, but growing stores should calculate the expected cost at higher sales levels.

Best for: Gift-box merchants needing personalization fields, templates, and potential recurring-box integrations.

Pricing: Free up to $500 in monthly box revenue; Grow $29/month; Scale $99/month.

App#5 MBC Bundle Builder

Best for Straightforward Custom Bundles

MBC Bundle Builder focuses on letting customers assemble customized bundles, gift boxes, starter kits, and product packs.

Merchants can create bundle pages and offer curated products for shoppers to combine into their own selections.

The app supports both single-step and multi-step layouts, so stores can choose between a more direct product-selection process and a guided experience.

What stands out

MBC includes essential bundle configuration options without requiring merchants to choose between several differently priced production tiers.

Its Growth plan advertises unlimited bundles, two layout types, multi-condition discounting, free-gift offers, storefront translations, and bundle sales analytics.

For example, a store selling candle gift sets could use the bundle builder to let customers assemble a personalized selection, with pricing or gift incentives configured around the offer.

The ability to use single-step or multi-step layouts is useful when different products require different levels of guidance.

What to consider before installing

MBC advertises a free plan, but that plan is limited to development and partner stores.

Regular live Shopify stores need the Growth plan at $19.99/month, which includes a 7-day free trial.

Although MBC supports custom bundle experiences and multiple layouts, merchants planning recurring subscriptions or developer-heavy headless implementations should confirm those requirements directly before committing.

Best for: Merchants who want a dedicated custom bundle builder with single-step and multi-step layouts at a fixed monthly price.

Pricing: Free for development and partner stores; Growth $19.99/month for live stores.

How to Choose the Right BYOB App for Your Store

The right Shopify BYOB app depends on what customers need to select, how you want the experience presented, and what the bundle is likely to cost you as sales grow.

If You're Launching Your First Guided Gift Box

Start by mapping the steps customers need to complete.

Do they only need to pick four products? Or should they select items, choose packaging, and enter personalization details?

For a simple product assortment, a mix-and-match builder may be sufficient. For a more structured experience, a Shopify multi-step bundle builder such as PushBundle, Easy Bundles, Easify, or MBC may be more appropriate.

Compare the actual plan required for your workflow, rather than choosing based on a free-plan label.

If You're Selling Subscription Boxes

Prioritize documented subscription compatibility.

Easy Bundles advertises subscription bundles on its Growth plan, while Easify lists subscription integrations for recurring boxes.

However, Shopify's product bundle eligibility and compatibility guidance identifies restrictions involving subscriptions and purchase options. A third-party app advertising subscription integrations doesn't automatically mean every subscription configuration will work.

Confirm the supported subscription provider, billing flow, inventory behavior, and checkout requirements before launching.

If You Need Extensive Storefront Customization

Kitenzo is worth considering for full-page experiences and headless development because it advertises a React SDK and API access.

Easy Bundles also advertises developer tools and customized bundle implementations.

If your store uses a standard Shopify theme, first assess whether a visual editor provides enough control. Custom development should solve a specific need rather than become an unnecessary requirement.

If Your Bundle Revenue Is Growing

Compare pricing models against expected revenue.

A free installation label doesn't necessarily mean ongoing usage is free. Some apps charge subscriptions, others move between revenue-based tiers, and Kitenzo charges per bundle transaction.

Here's how three pricing models compare at illustrative monthly bundle revenue levels:

Illustrative monthly software costs only, assuming revenue qualifies for the stated tiers, all Kitenzo bundle revenue is subject to the listed 1.5% fee, and no discounts or additional charges apply.

The numbers illustrate the billing models, not equivalent feature sets. A lower price doesn't automatically make an app a better match.

Also consider the cost of implementation, required integrations, subscription support, and whether the builder handles your intended selection rules.

Before committing, create a test bundle using your actual products and check product availability, quantity validation, mobile usability, pricing, and cart behavior.

Final Recommendation

The best BYOB Shopify apps solve different merchant problems.

PushBundle is worth considering for a guided Build Your Own Box experience with predictable monthly pricing. Easy Bundles may be a better fit for advanced workflows and subscription offers. Kitenzo provides customization and headless development options, while Easify and MBC offer different approaches to gift-box creation and pricing.

Choose based on the customer journey you want to create, the controls your products require, and the costs you can support as bundle sales grow.

If you're starting with personalized gift boxes, PushBundle's multi-step Build Your Own Box offers a way to create a guided experience without building a custom storefront.
