6 best Shopify BYOB apps for build-your-own bundles (2026)
A shopper wants three specific items in one box, not the fixed set you built for them. Without a way to pick their own combination, they either take the wrong bundle or leave without buying at all.
Six options as of September 2026, checked against Shopify's own App Store listings. BundleSuite carries the deepest review base. Mix and Match folds BYOB into a wider bundle toolkit. Oxify runs it free with no paid tier. Sledge is the one that keeps BYOB beside pre-order, search, and filters instead of running it alone.
// How we picked
How we chose these six
Every app here lets a shopper assemble their own set from products you choose, not just buy a fixed bundle. We ranked by review track record and by how far each app reaches beyond BYOB itself. Order reflects who you'd likely shortlist first, not who pays us, because nobody does.

// 1 · BundleSuite Bundle Builder
BundleSuite: the deepest review base in BYOB
BundleSuite runs mix and match, build-a-box, and BYOB from predesigned templates, plus fixed bundles and quantity breaks in the same app. 498 reviews at 5.0 stars as of September 2026, the largest base by a wide margin here.
The standout is template depth: a BYOB flow launches from a preset instead of a blank builder, and SKU sync keeps bundle stock tied to real inventory.
The honest limit: the free plan runs on development stores only, and the $12 Starter plan caps at $1,000 in monthly bundle sales before the $29 tier applies, so the bill can move with a good month.
Best for: you want the most-reviewed BYOB app and don't mind a plan that scales with bundle sales.
// 2 · Mix and Match Bundle Builder
Mix and Match Bundle Builder: BYOB inside a wide bundle toolkit
Built by Mageworx, this app runs BYOB alongside 10+ bundle types: fixed bundles, BOGO, quantity breaks, and add-ons, all from one page builder. 115 reviews at 4.9 stars as of September 2026.
The standout is range within one flow: a shopper can build their own box, then see a volume discount or a free-gift threshold apply automatically inside the same page.
The honest limit: the free plan covers development stores only. Live, the single Premium tier is $14.99 flat, which is simple but leaves no lower live-store tier to grow into.
Best for: you want BYOB and several other bundle types running from one builder.
// 3 · MBC Bundle Builder BYOB
MBC Bundle Builder BYOB: a dedicated step-by-step page
MBC Bundle Builder BYOB, by CPTN Limited, is named for the one job it does: a bundle page where a shopper picks their own combination, single-step or multi-step. 46 reviews at 4.9 stars as of September 2026.
What stands out is focus: bundle sales analytics and storefront translations ship on the same $19.99 plan, without a wider feature list to wade through.
The catch: the free plan is development stores only, and $19.99 is the highest flat entry price among the dedicated BYOB apps on this list.
Best for: you want a single, focused BYOB page and nothing else to configure.
// 4 · Push Bundle
Push Bundle: BYOB that also runs in Shopify POS
Push Bundle covers build-a-box, mix and match, and BYOB in 20 languages, with bundles working in Shopify POS as well as online. 16 reviews at 4.9 stars as of September 2026.
The standout is reach for stores selling in person: a bundle built online behaves the same at a POS register.
The honest limit: the free Starter plan covers volume discounts, not the multi-step BYOB builder itself; that needs the $14 Growth plan. The review base is also the smallest of the dedicated BYOB apps here.
Best for: you sell through Shopify POS and want BYOB to work the same in-store.
// 5 · Oxify Quantity Breaks & BYOB
Oxify: BYOB on the cheapest possible bill
Oxify runs build-a-box, BYOB, and mix and match alongside quantity breaks and BOGO, with no paid tier published at all. 12 reviews at 4.9 stars as of September 2026.
What sets it apart is the price: free is the only plan, not a capped starting tier, which makes it the one app on this list with no live-store bill to plan around.
The catch: no page-builder templates or POS support, and a smaller review base than the field's leaders, so support history is thinner to judge.
Best for: BYOB needs to cost nothing while you test whether shoppers want it.
// 6 · Sledge
Sledge: BYOB as one offer among many, on one bill
Every app above does bundles and little else. Sledge runs build-your-own-bundle as one of Nine offer types, alongside pre-order, search, filters, reviews, and the cart drawer, in one install.
The standout: one less subscription to run. A shopper who assembles their own set in search results sees the same bundle logic on the product page a moment later, and Growth Intelligence reads the results to name what to build next, in dollars.
Where it trails: the review count, 11 against 12 to 498 elsewhere, since Sledge is the newer entry. There's no free live-store plan either; $29.99 flat is the floor.
Best for: BYOB is one of several storefront jobs you'd rather run from a single plan than five.

Questions, answered
What's the best Shopify BYOB app?
It depends on the job. BundleSuite has the deepest review base and a template library. Mix and Match Bundle Builder pairs BYOB with 10+ other bundle types in one flow. Oxify runs BYOB on a genuinely free plan, no paid tier at all. Sledge is the pick if build-your-own-bundle should sit beside pre-order, search, and filters on one bill instead of running alone.
Is there a free Shopify BYOB app?
Oxify Quantity Breaks & BYOB is free outright, no paid tier published. BundleSuite, Mix and Match, and MBC Bundle Builder BYOB are free on development stores only; a live store needs the paid tier the moment BYOB goes live. Push Bundle's free Starter plan covers volume discounts but not the BYOB builder itself, which needs its $14 Growth plan.
What's the difference between BYOB and mix and match bundles?
BYOB (build your own bundle) lets a shopper assemble a custom set from products you choose, usually inside a box or kit flow. Mix and match usually applies one bundle price across a fixed product group instead. Most apps on this list, including Sledge, run both under one builder, so the distinction is more about the shopper's flow than the app you'd need.
Does a Shopify BYOB app also handle pre-order or discounts?
Rarely on one bill. The five competitors here are bundle specialists first; volume discounts and quantity breaks come built in, but pre-order, search, and reviews mean a separate app each. Sledge runs BYOB as one of {{ offers.liveWordCap }} offer types, alongside pre-order, search, filters, and reviews, on a single flat plan.
Let shoppers build the set, wherever they find it.
The five apps above run BYOB alone, on a bill that can move with bundle sales. Sledge keeps build-your-own-bundle beside pre-order, search, filters, and reviews on one $29.99 flat plan, and Growth Intelligence names what the bundle earned, in dollars.
