The 10 best Shopify bundle apps in 2026 (tested and compared)

A Shopify bundle app is a tool that lets merchants sell multiple products, or multiple units of one product, as a single discounted offer: Buy More and Save tiers, mix-and-match packs, or kits. Bundles exist for one reason: they raise average order value without raising ad spend.

The category is crowded and the App Store numbers hide the real differences. Nearly every serious bundle app shows 4.7 stars or better, so ratings alone will not pick your winner. What separates them is pricing structure (several "free" plans carry revenue caps), how the bundle widget is rendered on your page, and whether the bundle lives inside your design system or sits on top of it like a sticker.

Shopify bundle apps compared (July 2026)

Ratings and review counts are from the Shopify App Store as of July 2026, cross-checked against instant.so's published roundup of the category. Prices are the lowest paid tier at monthly billing.

Why do bundles lift average order value?

A bundle converts the moment of purchase intent into a bigger cart. The shopper has already decided to buy one unit; a well-placed Buy 2, Save 15 percent tier asks a much smaller question than the original purchase decision did. Because the discount only triggers on the larger order, you trade margin you were never going to earn for revenue you otherwise would not have captured. The same logic powers kits and mix-and-match offers: the second product rides on the conviction the first one earned.

The design detail most merchants miss: the bundle widget is often the single most-viewed block on a product page after the price. A widget that inherits generic styling, clashing fonts, or default colors quietly costs conversions on the exact element that is supposed to raise them.

1. EcomWize: bundles built into the page, not bolted on

EcomWize takes a structurally different approach: it is an AI Shopify page builder with bundles built in, not a standalone bundle widget. Buy More and Save tiers, a cart drawer with a rewards bar, and one-tap upsells ship inside the same product as the landing page builder, so the bundle offer, the page around it, and the cart upsell share one design system and one brand style. There is no visual seam where a third-party widget starts.

The economics follow the same logic. Bundles are included in the page builder subscription: one 49 dollar Starter plan covers AI-generated pages, the cart drawer, and bundle offers, instead of a page builder plus a 10 to 15 dollar bundle app as separate line items. There are no revenue-based fees and no revenue caps at any tier; the free plan is metered by AI credits (150 per month), not by how much your bundles sell. Everything publishes as native Shopify Liquid, so bundle blocks load at theme speed and pages keep working if you cancel.

The honest caveat: EcomWize is a new App Store listing with no rating history yet, and it makes sense as a bundle solution when you also want the page builder. If you only need a widget dropped into an existing theme and nothing else, a dedicated app below may be the shorter path.

2. Kaching Bundles: the category's ratings leader

Kaching Bundles holds a flat 5.0 stars across 4,632 reviews as of July 2026, the strongest rating-to-volume combination in the category. The product is focused: quantity breaks and bundle blocks that drop onto product pages, with solid customization and a reputation for responsive support. At 14.99 dollars per month it sits mid-pack on price. The catch is the free plan: it is free only on development stores, so every live store pays from day one. For a proven, single-purpose quantity-break widget, it is the safe default.

3. Pumper Bundles: cheap entry, tight free cap

Pumper (4.9 stars, 2,987 reviews) undercuts most of the list at 9.99 dollars per month and offers a genuinely free tier, with the industry's now-standard trick attached: the free plan caps you at 300 dollars per month in bundle-generated revenue. That is roughly six or seven bundle orders for a typical DTC store. Read it as a free trial that meters success rather than time: the moment bundles work, you upgrade. As a paid app it is one of the better value picks.

4. Bundler: the genuinely free option

Bundler (4.9 stars, 1,871 reviews) is the outlier on economics: its free plan is advertised with no limits, no revenue caps, and most core bundle types included, with a 9.99 dollar Premium tier for advanced features. If your constraint is budget and your theme handles the widget styling acceptably, Bundler is the rational starting point, and its review volume suggests plenty of stores never leave the free tier. The interface is more utilitarian than the newer apps, which is the main trade.

5. Simple Bundles: the variant-limit escape hatch

Simple Bundles (4.9 stars, 661 reviews, 24 dollars per month, free up to 3 bundles) earns its higher price with one technical superpower: it builds bundles that bypass Shopify's 2,048-variant limit per product. For stores selling configurable kits, multipacks with many size and flavor combinations, or inventory-synced sets, that constraint is the whole ballgame, and Simple Bundles is the established answer. If you have never hit the variant wall, you probably do not need to pay for the escape hatch.

6. Koala Bundles: the fast-rising challenger

Koala Bundles (4.9 stars, 662 reviews, 12.99 dollars per month) competes head-on with Kaching on quantity breaks and bundle deals, with a modern widget and aggressive iteration. It has accumulated its review base quickly, which usually signals strong onboarding and support. There is little to fault at the price; choosing between Koala and Kaching mostly comes down to which widget previews better on your theme.

7. Shopify Bundles: official, free, and rated 2.8 stars

Shopify's own bundles app is free forever, first-party, and rated 2.8 stars across 577 reviews, the lowest score on this list by a wide margin. The complaints are consistent: it creates fixed bundles as products but offers little control over discounts, presentation, or quantity-break mechanics, the exact features merchants install a bundle app to get. It is worth trying first precisely because it is free and official; just know that its rating reflects merchants discovering the ceiling quickly.

8. MaxBundle: budget pick with a revenue cap

MaxBundle (4.8 stars, 487 reviews) matches Pumper at 9.99 dollars per month and runs the same free-plan playbook with a slightly looser cap: free until your bundles generate 500 dollars in revenue. It covers the standard set, quantity breaks, mix-and-match, and upsell-style offers, at the low end of the price range. A sensible pick if you want a real free runway before paying, and you accept that success triggers the upgrade.

9. Amplify: the premium suite, no free anything

Amplify (4.7 stars, 531 reviews) is the category's premium play at 99.50 dollars per month with no free plan. The pitch is a full AOV suite rather than a single widget, aimed at higher-volume stores that want bundles, upsells, and offer logic under one roof with dedicated support. At ten times the price of the budget apps, it needs your bundle revenue to already be a meaningful line item. Most stores under seven figures will not get their money's worth.

10. Wide Bundles: replaces the variant selector

Wide Bundles (4.9 stars, 276 reviews, 14.99 dollars per month) takes the boldest design position: it replaces your product page's variant selector entirely with a bundle-style offer block, a pattern popular with single-product and dropshipping stores running paid traffic. When the whole page is built around one offer, that works beautifully. On multi-variant catalog stores it can fight your theme, so know which kind of store you are before installing.

How we compared these apps

• Pricing structure: the lowest paid tier, and what the free plan actually allows before charging, including revenue caps and dev-store-only terms.
• Rating and volume: App Store rating and review count as of July 2026, weighted together since a 4.9 across 2,000 reviews beats a 5.0 across 20.
• Rendering and design: whether the bundle inherits your brand styling or ships a widget with its own look, and what that does to page speed.
• Scope: single-purpose widget versus part of a larger AOV or page-building stack.

Which bundle app should you choose?

Every bundle app raises your average order value the same way. The differences are what the free plan hides, and whether the widget looks like your brand or like an app.

• Choose EcomWize if you want bundles, the landing page, and the cart upsell designed as one system under one subscription, with no revenue-based fees.
• Choose Kaching Bundles if you want the most proven standalone quantity-break widget and do not need a free tier.
• Choose Bundler if budget is the constraint: its free plan is the only genuinely uncapped one on this list.
• Choose Simple Bundles if you sell kits that hit Shopify's 2,048-variant limit.
• Choose Pumper or MaxBundle if you want a cheap paid plan with a free runway first, and you accept the revenue cap.
• Choose Amplify if bundle revenue is already large enough to justify a 99.50 dollar suite.
• Choose Wide Bundles if you run single-product offer pages on paid traffic.
• Try Shopify Bundles first if your needs are truly minimal; it is free, and its 2.8-star rating will tell you when you have outgrown it.
