The best Shopify bundle builder apps in 2026 are NeatBundles, Kitenzo, Boxi, MBC Bundle Builder and FoxSell. Pick NeatBundles for step-by-step flows with gift notes, photos and dates and a free start, Kitenzo for headless stores, Boxi for per-product personalization, MBC for one flat price, and FoxSell for fixed and volume bundles in the same app.
We build NeatBundles, so it's one of the five. The other four are the bundle builders merchants most often mention to me. There's no ranking here: each app is strong at a different part of the builder, and this post compares those parts one question at a time.
We keep track of how these apps change, and pricing has moved a lot this year. Kitenzo went from $300 a month plus a 1% fee to 1.5% per bundle transaction with no monthly fee, and MBC Bundle Builder replaced its tiers by Shopify plan with one $19.99 plan. Every rating, review count and price below was checked on the live Shopify App Store listings and each app's own help and pricing pages on November 10, 2026.
You need an app for any of this. Shopify's free Bundles app creates fixed bundles and multipacks, where every shopper gets the same set, and it has no page where the shopper builds their own.
Key takeaways
- All five apps build a full bundle page where shoppers pick their own products. They differ in the flow (one page or steps), the personalization fields, how far you can change the design, and how they charge.
- NeatBundles has the widest set of personalization fields on every plan: text, long text, number, photo upload, multiple choice, date and date and time.
- For a fully custom or headless front end, Kitenzo (React SDK and headless API) and FoxSell (custom bundle designs on its Enterprise plan) go furthest.
- NeatBundles is free to use up to $500 of bundle sales a month with every feature. FoxSell's free plan goes to $1,000; Kitenzo, Boxi and MBC charge from the first sale on a live store.
The five bundle builder apps at a glance
The table below compares the five Shopify bundle builder apps on their builder flows, free option, entry price and rating, as listed on the Shopify App Store on November 10, 2026.
| App | Builder flows | Free on a live store | Paid from | Rating |
|---|---|---|---|---|
| NeatBundles | One page or guided steps | Up to $500 of bundle sales a month | See pricing | 4.9 (6) |
| Kitenzo | Full page with steps, embeds, headless | No | 1.5% per bundle sale, no monthly fee | 4.4 (265) |
| Boxi | Step-by-step page or embed | No, 14-day trial | $21/mo, up to $1,000 of bundle sales | 5.0 (26) |
| MBC Bundle Builder | Single step or multi-step | No, development stores only | $19.99/mo flat | 5.0 (42) |
| FoxSell | Mix and match, guided steps, plus fixed and volume bundles | Up to $1,000 of bundle sales a month | $49/mo, up to $5,000 of bundle sales | 5.0 (102) |
Read the review counts next to the stars. Our 4.9 rests on six reviews and Kitenzo's 4.4 on 265, so the newer apps have a shorter track record to judge.
Can shoppers build the bundle on one page or step by step?
A bundle builder is a page where shoppers assemble their own bundle from products you choose, see a running summary and price, and add the whole bundle to the cart in one go. All five apps can do it on one page or over several steps. What differs is how much control you get over each step.
In NeatBundles you choose the layout when you create the bundle. Build Your Own Bundle puts every product on one page next to a "Your Bundle" panel. Here's a cookie box from our demo store with the three-cookie limit reached: the other cookies grey out and the 15% discount shows in the total.
Guided Bundle splits the choice into steps, one category per step, and you set how many products a shopper must pick in each. This skincare routine has six steps; the first asks for two or three cleansers before Next step unlocks.
Each step takes products or whole collections, can allow or block the same product twice, and can preselect or require a product (like the box itself). When the bundle is complete, you choose whether shoppers go to the cart or straight to checkout. The guided bundles feature page shows the step settings.
The other four handle the flow like this:
- Kitenzo sets "how many items shoppers choose at each step" in a visual builder and adds required products and validation. It also runs as an embed or a headless front end.
- Boxi builds full-page builders "with step-by-step workflow" and can publish them as a standalone page or embed them on any page.
- MBC Bundle Builder offers "2 layouts: single step and multi-step" on its paid plan, with two storefront templates: Stepper (one step at a time) and Accordion (all steps on one page, opened one at a time).
- FoxSell has a Guided Steps template for step-by-step mix and match, plus a tiered builder. It's the only one of the five that also sells fixed bundles of up to 30 products and volume bundles with quantity breaks.
Can shoppers add a gift note, photo or date to the bundle?
Yes in NeatBundles, Boxi and Kitenzo, which differ in the field types they offer. MBC Bundle Builder and FoxSell don't document personalization fields in their listings or help centers, so for gift boxes with a message they're the weaker fit.
In NeatBundles you click Include personalization step and add fields to it: short text, long text, number, photo upload, multiple choice, date, or date and time, each optional or required. You can also place personalization steps anywhere in a guided flow, not only at the end. The answers show on the order next to the bundle. Here's the cookie box's second step, with From, To and Message filled in:
How the others compare:
- Boxi personalizes the whole box with custom fields on every plan, and single products inside the box (including a photo upload) from its $79 Advanced plan. Per-product fields are something NeatBundles doesn't have; our fields belong to the bundle.
- Kitenzo documents a notes block (a free-text field), and its gifts page adds a gift message field and a delivery date block. Photo uploads and multiple choice aren't documented.
- MBC Bundle Builder and FoxSell: not documented.
The personalized bundles feature page shows every NeatBundles field type with an example.
How much of the builder's design can you change?
Every app here lets you match the builder to your theme without code. The difference is what happens when the built-in settings aren't enough: some apps hand you CSS, some do the work for you, and two let a developer replace the front end entirely.
- NeatBundles has a design editor with a live preview: color palettes or your own colors for buttons, text, badges and the bundle panel, border radius, product image shape and fit, and dropdown or swatch variant pickers. Texts are translatable from the Translations page. Custom work beyond that goes through our support chat.
- Kitenzo combines a visual editor (layout, typography, color, spacing) with a React SDK and a headless API, so the same bundles can run on a Hydrogen or custom storefront. Its plan includes "Merchant Success and design support".
- FoxSell styles its widgets in the Shopify theme editor, adds theme customisations from its $149 Scale plan, and lists "Custom Bundle Design" on its Enterprise plan. That's a design built for you and connected to FoxSell's backend.
- MBC Bundle Builder has a Customize design window plus custom CSS and JavaScript, and its paid plan includes "Free personal design customization" by its team, which is rare among bundle apps.
- Boxi has a visual editor for colors, layout and product cards, with more visual options on the $35 Regular plan.
Can you see which bundles sell?
Yes in NeatBundles: the Analytics page shows bundle revenue, bundles sold, average bundle value, average order value and bundle conversion, with revenue over time and sales by bundle, on every plan. That tells you whether a builder is adding to your average order value and which bundle to promote.
- Kitenzo includes Advanced Reporting and A/B testing on its one plan, which no other app here documents.
- FoxSell shows bundle revenue, bundle units sold and the split by bundle type.
- MBC Bundle Builder lists bundle sales analytics on its $19.99 plan.
- Boxi: analytics aren't documented in its listing or help center.
Bundle builder features side by side
App Store feature lists all look alike, so I checked each app's listing, help center and pricing page for the features that shape a builder flow. "Not documented" means I couldn't find it on November 10, 2026, not that it's impossible.
| Feature | NeatBundles | Kitenzo | Boxi | MBC Bundle Builder | FoxSell |
|---|---|---|---|---|---|
| Free on a live store | Up to $500 of bundle sales a month | No, 1.5% from the first sale | No, 14-day trial | No, dev stores only | Up to $1,000 of bundle sales a month |
| Built for Shopify badge | Yes | Yes | Yes | Yes | Yes |
| Single page builder | Yes | Yes | Yes | Yes | Yes |
| Multi-step builder | Yes | Yes | Yes | Yes | Yes, Guided Steps template |
| Personalization fields | Text, long text, number, photo, multiple choice, date, date and time | Notes, gift message, delivery date | Box fields; product fields and photos from $79 | Not documented | Not documented |
| Personalization steps anywhere in the flow | Yes | Not documented | Custom data step | Not documented | Not documented |
| Free gift in the bundle | Yes, fixed, shopper's choice or free shipping | Yes, free gift rules | Not documented | Yes | Yes |
| Discount tiers inside one bundle | % off, amount off, bundle price or price per product | Fixed, %, tiered, volume, conditions | Flat or tiered | Multi-condition discounts | Fixed or dynamic price, tiered builder |
| Fixed and volume bundles | In development | Fixed bundles | Not documented | Fixed bundles | Yes, both |
| Discounts without generated codes | Yes, Shopify Cart Transform | Yes, Cart Transform | Not documented | No, creates a code per bundle | Not documented |
| Design control | Design editor, palettes, translations | Visual editor, React SDK, headless API | Visual editor | Customize design, CSS and JS, free custom design | Theme editor, custom design on Enterprise |
| Analytics | Every plan | Advanced Reporting, A/B tests | Not documented | $19.99 plan | Bundle analytics |
| Shopify POS | No | Not documented | Not documented | Not documented | Yes |

Where NeatBundles is ahead of the other four
NeatBundles is a Shopify bundle builder app for build your own bundle pages, multi-step guided bundles and personalized gift boxes, and it's free to use up to $500 of bundle sales a month. Against the other four, it's ahead in five specific places:
- Personalization depth. Seven field types on every plan, including photo uploads, multiple choice and date and time, and personalization steps placed anywhere in the flow. Boxi puts photo uploads on its $79 plan; MBC and FoxSell don't document fields.
- No plan gates. Every feature is on every tier, from analytics to translations to prices per currency; only the bundle sales allowance changes. The tiers are on the pricing page.
- Pricing rules. A rule checks products picked, bundle value or bundles in the cart, then takes a percentage or amount off, sets a bundle price or sets a price per product. Rules stack into tiers with a live progress bar.
- Clean checkout. The discount applies through Shopify's Cart Transform, so no discount codes pile up in your admin and the bundle reaches checkout as one line with its products listed under it.
- Free gifts with a choice. A bundle can unlock a fixed free product, a free product the shopper picks, or free shipping.
And what it doesn't do:
- It's young. The listing went live in January 2025 and has 6 reviews. It does have the Built for Shopify badge, Shopify's mark for apps that meet its standards for speed, design and integration.
- Fixed and volume bundles are in development. Today NeatBundles builds builder bundles only, without fixed bundles, volume bundles or product-page quantity breaks; FoxSell covers those in one app now.
- Headless SDK in development, no POS. A headless SDK is on the way; for a Hydrogen or custom React storefront today, Kitenzo is built for it. Bundles don't sell through Shopify POS.
The other four apps in short
Kitenzo Bundle Builder
Kitenzo has been on the App Store since 2017 and is the most developer-oriented builder here. It's the enterprise option for stores that need conditional logic: its rules decide product visibility, required items, volume pricing and free gifts.
It charges 1.5% of each bundle sale with no monthly fee, capped at $10,000 per 30 days, and development stores are free until launch. The rating is the lowest here, 4.4 from 265 reviews with 11% at one star, so read the recent ones.
Boxi
Boxi is a gift box specialist launched in May 2024, rated 5.0 from 26 reviews. It's the pick when each product in a box needs its own personalization, like a printed photo frame. It has no free plan: after a 14-day trial it's $21 a month up to $1,000 of bundle sales, then $35, $79 and $189, and multi-language, market pricing and per-product fields sit on the $79 Advanced plan.
MBC Bundle Builder
MBC Bundle Builder is the full-page builder from the team behind MBC Mix and Match Bundles, rated 5.0 from 42 reviews. One flat $19.99 a month with "No additional fees" makes it predictable at high volume, and its free design customization is generous. Two things to know: it's only free on development stores, and its help center says it creates a unique discount code when shoppers build a bundle, with a setting to clean up unused codes.
FoxSell Bundle Builder
FoxSell, rated 5.0 from 102 reviews, is the widest app here: mix and match and guided builders plus fixed bundles, multipacks and volume bundles, with Shopify POS support. The free Starter plan covers up to $1,000 of bundle sales a month, and Pro is $49 a month up to $5,000. Custom designs built with an agency are its standout, and they sit on the Enterprise plan.
Which bundle builder fits your store?
The right bundle builder depends on what shoppers need to do in it and how your store is built. Here's how I'd decide:
- Shoppers build a box or routine over several steps and add a note, photo or date: NeatBundles, free to start. For a walkthrough, see how to create guided bundles on Shopify.
- Shoppers pick from one grid with a pick limit and a discount: NeatBundles' Build Your Own Bundle page, or MBC if you prefer one flat price.
- Each item in the box is personalized on its own: Boxi on the Advanced plan.
- You run a headless storefront or want A/B tests: Kitenzo.
- You want a builder plus fixed bundles and quantity breaks in one app, or an agency-built design: FoxSell.
If your bundles are about where the mix happens (a bundle page, a product-page widget or a quantity selector), the mix and match bundle apps comparison splits them that way. For gift boxes specifically, see the gift box apps comparison.
Tip: Build the same bundle in two apps' demo stores on your phone before installing. A step flow that feels clear on a desktop can take five taps too many on mobile.
Frequently asked questions
Which Shopify app is best for a multi-step bundle builder?
NeatBundles, Kitenzo, Boxi, MBC Bundle Builder and FoxSell all build multi-step bundles. NeatBundles adds personalization steps with photo, date and multiple choice fields on every plan and is free up to $500 of bundle sales a month. Kitenzo suits headless stores, and FoxSell adds fixed and volume bundles.
Is there a free Shopify bundle builder app?
Yes. NeatBundles is free to use up to $500 of bundle sales a month with every feature, and FoxSell's Starter plan is free up to $1,000. Kitenzo charges 1.5% from the first sale, Boxi starts at $21 a month after a trial, and MBC Bundle Builder is free only on development stores.
Can customers add a gift message or photo to a bundle on Shopify?
Yes, with the right app. In NeatBundles you add a personalization step with text, photo upload, date or multiple choice fields, and the answers appear on the order. Boxi offers box fields on every plan and photo uploads on its $79 plan. Kitenzo documents a notes field, a gift message and a delivery date.
Can I use my own custom design with a bundle builder app?
Partly in every app and fully in two. Kitenzo offers a React SDK and headless API for custom front ends, and FoxSell builds custom bundle designs on its Enterprise plan. NeatBundles, Boxi and MBC Bundle Builder use design editors on your theme, and MBC adds custom CSS and JavaScript.
Is this comparison biased toward NeatBundles?
We build NeatBundles, so read it with that in mind. To keep it fair, there's no ranking, every price and rating comes from the live listing with the check date, features a competitor doesn't document are marked "Not documented" rather than "No", and the places where another app fits better are named.
Before you install a bundle builder
These five apps look alike on a feature list and differ a lot once a shopper uses them. Before you choose:
- Decide the flow: one page, or steps with a pick limit in each.
- List the fields your bundle needs (a gift note, a photo, a delivery date) and check which plan has them.
- Price each app at a normal month and a peak month of bundle sales.
- Recheck the listing on the day you install. Kitenzo and MBC Bundle Builder both changed their pricing model this year.
If a step-by-step builder with personalization is what you're after, you can install NeatBundles from the Shopify App Store and build your first bundle for free.
