20 Best Bundle Apps for Shopify (September 2026): Every Rating, Price & Free Plan Verified

Short answer: the best bundle app for Shopify depends on the job. For quantity breaks, mix and match, a build-your-own-box builder and BOGO in one app, our pick is our own Oxify Quantity Breaks & BYOB; for the most merchant proof, Kaching Bundles; for free, AOV.ai or Bundler; for inventory and 3PL, Simple Bundles & Kits.

The figures behind those picks: Oxify Quantity Breaks & BYOB has 4.9 ★ from 13 reviews and one flat plan at $14.99/mo after a 14-day trial. Kaching Bundles has 5.0 ★ from 6,264 reviews and starts at $14.99/mo. AOV.ai Bundles Quantity Breaks (5.0 ★, 1,653 reviews) lists no paid plans, and Bundler (4.9 ★, 2,722 reviews) has a free plan with no revenue or order cap. Simple Bundles & Kits (4.9 ★, 803 reviews) has a free plan and paid plans from $14/mo. For mix and match and builder pages on large catalogs, look at FoxSell Bundle Builder (5.0 ★, 95 reviews, free up to $1,000/mo in bundle sales).

Every rating, review count and price on this page was read from the live Shopify App Store listing on September 18, 2026; for nine of the apps we re-read it on October 11, 2026. We make one of these apps, so the disclosure and method are right below, before any ranking.

How we checked these apps

What we did. On September 18, 2026 we loaded all 20 App Store listings and recorded the rating and review count from each page's structured data, the plan names, prices and limits from the pricing section, and whether the Built for Shopify badge appears next to the app's own title. We also confirmed each listing returns a live page with an install option. On October 11, 2026 we re-read nine of them (Oxify Quantity Breaks & BYOB, Kaching Bundles, BOGOS, Pumper, Fast Bundle, Bundler, AOV.ai, Simple Bundles & Kits and Easy Bundles): their ratings, badges and headline plan prices matched what we recorded in September, and their review counts had grown (Oxify's stayed at 13). The other eleven apps still show their September 18 figures.

What we did not do. We did not run speed benchmarks, and we have not run every rival app on a production store. Feature lists for other apps come from their own listings, so treat them as the developer's claims. Where we mention performance, we rely on the published Built for Shopify requirements, not our own lab data.

How the order was decided. Feature coverage (how many bundle types, and whether there is a real builder), pricing transparency, review evidence, how inventory is handled, and the honesty of the free plan. Ratings move weekly, so confirm the current listing before you install.

Best bundle apps for Shopify: comparison table (2026)

All 20 rows were read from the live Shopify App Store listings on September 18, 2026; the ratings and review counts for Oxify, Kaching, BOGOS, Pumper, Fast Bundle, Bundler, AOV.ai, Simple Bundles & Kits and Easy Bundles were refreshed on October 11, 2026. "Free up to $X" means the free plan ends once the app attributes that much monthly revenue to its offers.

How to choose a bundle app in 60 seconds

1. Does a warehouse or 3PL pick your orders? Yes: Simple Bundles & Kits. Stop here.
2. Is your budget zero? AOV.ai or Bundlex (both list only a free plan), or Bundler's uncapped free plan.
3. Do shoppers build their own box? Oxify, FoxSell or Easy Bundles. For very large variant counts, FoxSell.
4. Is it one hero product with "buy 2, save 10%" tiers? Pumper, Kaching or Oxify.
5. Are gifts and BOGO campaigns the main job? BOGOS.
6. None of the above? Pick the app with a free tier that covers your current bundle revenue, test one offer for two weeks, and only then pay.

How Shopify's own App Store ranks bundle apps

The App Store's product bundles category is the ranking most merchants actually see. On October 11, 2026 its first twelve positions were: BOGOS, SMART Bundles Volume Discounts, Bundlex, Easy Bundles, Selleasy, Kaching Bundles, Simple Bundles & Kits, Pumper, Moon Bundles, Supr Bundle & Subscription, Easify Box Bundle Builder and Loop Subscriptions. The order changes often (on September 18 it opened with Kaching Bundles, Selleasy and Pumper) and Shopify does not publish the formula.

Seven of those twelve are reviewed in full below. We left out Selleasy (an upsell and add-on app more than a bundle app), Supr and Loop (subscriptions first), Easify (it overlaps closely with Easy Bundles) and SMART Bundles Volume Discounts, which was not in the top twelve on September 18 and which we have not reviewed. If one of them fits your store better, the category page links to each listing.

Accuracy audit: where other 2026 roundups are out of date

We read the guides that currently rank for this topic and compared what they say with the live listings. This is not a criticism of those authors, since listings change constantly. It is a reason to check the App Store before you trust any roundup, this one included.

Cart-transform vs variant-based bundles

One technical difference explains most bundle inventory problems, so understand it before you compare features.

• Variant-based bundles create a new product or variant that stands for the bundle. Setup is simple, but the app has to keep the bundle's stock in line with its components, and large option sets run into Shopify's variant limits.
• Cart-transform bundles use Shopify's Cart Transform Function API to merge or expand line items in the cart. The component products stay as they are, so stock is deducted from the real SKUs and discounts apply without codes.
• SKU breakdown goes a step further: the order itself is rewritten into component SKUs so a 3PL, warehouse system or ERP picks real items. Simple Bundles & Kits is built around this.

If a listing does not say how it handles inventory, ask support before you install. It decides whether your bundles run themselves or need manual stock fixes.

Which bundle apps request cart-transform access?

Each App Store listing shows the store data an app requests under Data access. On October 11, 2026 we read that section for nine of the apps on this page. Five list "Cart transforms" under Shopify Functions: Oxify Quantity Breaks & BYOB (our app), Kaching Bundles, FBP | Fast Bundle & Upsell App, Simple Bundles & Kits and AOV.ai Bundles Quantity Breaks. Pumper's Data access section does not list it. The Easy Bundles, BOGOS and Bundler listings showed no Data access section in the page we fetched, so we cannot say for those three. The listing shows what an app asks for, not how each bundle type is built, so ask support whether your bundles use cart transforms or variants.

The 20 best Shopify bundle apps, reviewed

1. Oxify Quantity Breaks & BYOB (best all-in-one, and our own app)

• Rating: 4.9 ★ (13 reviews), Built for Shopify, launched July 30, 2025
• Price: One paid plan, Awesome, at $14.99/mo or $129.99/yr (save 28%), with a 14-day free trial. Every feature is included, and there is no free plan and no bundle or order cap.
• Best for: Stores that want quantity breaks, mix and match, a Build Your Own Box builder and BOGO in one app.

Oxify Quantity Breaks & BYOB is our app, as disclosed above. We list it first because it covers the most bundle formats of any app here without needing a second tool, not because of its review count, which is the smallest on this page.

Pros:

• Quantity breaks, tiered pricing, fixed bundles, multipacks, mix and match and a BYOB bundle builder in one widget set
• BOGO, Buy X Get Y and auto-added free gifts, applied at checkout without codes
• A/B testing and a revenue analytics dashboard
• Listed as working with subscriptions apps, GemPages, PageFly, EComposer and cart drawers including Oxify Cart Drawer & Upsell (a separate app, 4.9 ★ from 40 reviews), UpCart and AOV.ai

Cons: Thirteen reviews is a thin track record next to apps with thousands. It does not rewrite orders into component SKUs for a 3PL. It has no free plan, so the entry price is $14.99/mo after the 14-day trial, the same as Kaching, and Bundler and AOV.ai cost less.

Verdict: The broadest single-app feature set here and cheap to try. If you need years of social proof, choose Kaching; if you need warehouse-grade SKU handling, choose Simple Bundles.

2. Kaching Bundles App & Upsells (most reviewed)

• Rating: 5.0 ★ (6,264 reviews), Built for Shopify, launched August 11, 2022
• Price: Starter $14.99/mo (up to $1,000 of additional revenue), Scale $29.99/mo (up to $5,000), Pro $59.99/mo (up to $10,000). 7-day trial. Free for development stores only.
• Best for: Merchants who want the app that the most stores have already vetted.

Kaching is the most reviewed bundle app on the App Store, and 98% of those reviews are five stars.

Pros: Quantity breaks, BOGO, fixed and mix-and-match bundles, subscription bundles, free gifts, progress bars, A/B testing and a revenue dashboard. Its listing shows it working with Shopify POS, Hydrogen, PageFly, GemPages and UpCart.

Cons: No free plan for a live store, and every tier is capped by the revenue Kaching attributes to itself, so the bill steps up as offers succeed. It is centered on product-page deal blocks rather than a dedicated bundle-builder page.

Verdict: The safest choice on reputation. See our Kaching Bundles alternatives guide if the missing free plan is a problem.

3. BOGOS: Free Gift Bundle Upsell (best for promotions)

• Rating: 5.0 ★ (4,474 reviews), Built for Shopify, launched December 17, 2014
• Price: Free for 30 orders over the lifetime of the account. Basic $29.99/mo (300 orders a month), Grow $49.99/mo (600 orders), Plus $109.99/mo (2,000 orders), with $0.05 per extra order. 7-day trial on paid plans.
• Best for: Stores that run frequent gift-with-purchase and BOGO campaigns, including on POS or headless storefronts.

Pros: BOGOS covers free gifts, BOGO and Buy X Get Y, mix and match, volume discounts and frequently bought together, and lists support for Shopify POS, Shopify Flow and Hydrogen.

Cons: The free plan is effectively a trial. The bundle builder starts on the Basic plan and checkout upsells need Plus. Order-based pricing with overage fees makes busy promotional months cost more.

Verdict: The strongest promotions engine here. Budget for a paid plan from the first day.

4. Pumper Bundles Quantity Breaks (best for quantity breaks)

• Rating: 4.9 ★ (3,551 reviews), Built for Shopify, launched May 15, 2023
• Price: Free up to $300 of revenue generated. Starter $9.99/mo (up to $1,000), Growth $29.99/mo (up to $5,000), Unlimited $49.99/mo. 7-day trial.
• Best for: Single-product and small-catalog stores built around "buy more, save more" offers.

Pros: Pumper offers unlimited bundles and quantity breaks on every plan, free gifts and BOGO, page-builder support and integrations with common cart drawers and cash-on-delivery apps. The Unlimited tier caps the bill at $49.99.

Cons: No dedicated bundle-builder page and no SKU breakdown for fulfillment.

Verdict: A very good value volume-discount app. Look elsewhere for BYOB or warehouse workflows.

5. FBP | Fast Bundle & Upsell App (most bundle types)

• Rating: 5.0 ★ (3,539 reviews), launched November 26, 2020. No Built for Shopify badge on the listing as of October 11, 2026.
• Price: $19/mo (up to $1,000 in monthly bundle sales), $49/mo (up to $3,000), $139/mo (up to $10,000). 7-day trial. Free for development stores only.
• Best for: Stores that want many bundle formats plus AI-suggested frequently bought together offers.

Is Fast Bundle still on the Shopify App Store? Yes. The app was removed from the App Store on July 18, 2026 and later reinstated. It is live at apps.shopify.com/fast-bundle-product-bundles with its reviews intact, although the listing no longer shows the Built for Shopify badge that older articles mention. On October 11, 2026 the listing was still live without the badge.

Pros: Fixed bundles, mix and match, a bundle builder, BOGO and Buy X Get Y, add-ons, volume discounts, AI frequently bought together, an AI image generator and Shopify POS support.

Cons: No free plan for live stores, a steep jump from $49 to $139, and no SKU breakdown for 3PLs. The recent delisting is worth factoring into a decision before a peak season.

Verdict: Feature-rich and well reviewed. Ask its support about the delisting and the badge before you commit.

6. Vitals: Reviews, Bundles & 40+ (best if you want one app for everything)

• Rating: 4.9 ★ (2,950 reviews), Built for Shopify, launched March 16, 2018
• Price: One plan at $29.99/mo with a 7-day trial. The listing states that usage fees begin once Vitals-attributed sales pass roughly $1,000 a month.
• Best for: Stores that would otherwise pay for separate reviews, upsell, wishlist and pop-up apps.

Pros: Vitals bundles product reviews, fixed and mix-and-match bundles, volume discounts, BOGO, gifts, sticky add to cart, back-in-stock alerts and more into one subscription, and integrates with Shopify Flow and Klaviyo.

Cons: Bundling is one module among more than 40, so it is less deep than a specialist. You pay $29.99 even if you only use bundles, and the usage fees need reading before you scale.

Verdict: Good value when it replaces three or more apps. Poor value as a bundle app alone.

7. Bundler » Product Bundles App (best uncapped free plan)

• Rating: 4.9 ★ (2,722 reviews), Built for Shopify, launched July 2, 2019
• Price: Free plan with unlimited revenue and orders. Premium $9.99/mo, Executive $19.99/mo, each with a 7-day trial.
• Best for: New stores that want classic bundles and volume discounts without a revenue meter.

Pros: The free plan of Bundler includes Buy X Get Y, volume discounts and quantity breaks, product-page upsells, Shopify POS and auto-applied discounts. Paid plans are flat, not revenue-based.

Cons: Mix and match, custom landing pages and funnel upsells need Premium, and analytics need Executive. No SKU breakdown.

Verdict: The most generous free tier among established apps, and the cheapest route to mix and match at $9.99.

8. AOV.ai Bundles Quantity Breaks (best entirely free app)

• Rating: 5.0 ★ (1,653 reviews), Built for Shopify, launched September 26, 2024
• Price: Free. No paid plans are listed.
• Best for: Stores that want a builder page and volume discounts at no cost.

Pros: AOV.ai lists volume discount tiers, frequently bought together, mix and match, fixed bundles, bundle-builder pages and 24/7 chat support, and pairs with the developer's own cart drawer.

Cons: A free app has to be funded somehow, usually by the developer's paid products, and pricing can change. Fewer advanced controls such as A/B testing.

Verdict: The best no-cost option today. Re-check the pricing section before you build a campaign around it.

9. Rapid Bundles & Upsell, formerly Rapi (best free-to-start upsell funnel)

• Rating: 5.0 ★ (1,540 reviews), Built for Shopify, launched January 3, 2022
• Price: Forever Free up to $100 a month of generated revenue. Starter $15/mo (up to $1,000), Pro $29/mo (up to $10,000), Elite $59/mo (unlimited). 7-day trial on paid plans.
• Best for: Stores that want bundles and post-purchase upsells from one app with clearly published thresholds.

Pros: The app still lives at apps.shopify.com/rapi but is now titled "Rapid Bundles & Upsell app". It lists volume discounts, BOGO, mix and match, subscription bundles, unlimited post-purchase upsells even on the free plan, and A/B testing on Pro. Pro covers up to $10,000 for $29, which is generous next to rivals.

Cons: The $100 free threshold is reached quickly. API access is reserved for Elite.

Verdict: Strong pricing for growing stores, particularly if post-purchase offers matter to you.

10. Koala Bundles Volume Discounts

• Rating: 4.9 ★ (808 reviews), Built for Shopify, launched March 11, 2024
• Price: Kickstart $12.99/mo (up to $1,000 monthly revenue), Scale Koala $19.99/mo (up to $5,000), Unlimited $59.99/mo. 14-day trial. Free for development stores only.
• Best for: Volume discounts paired with post-purchase upsells, countdown timers and announcement bars.

Pros: Koala Bundles has the longest trial among the paid-only apps and a low $19.99 middle tier.

Cons: No free plan for live stores, and no bundle-builder page. Shopify's own blog still describes a free plan that the listing no longer shows.

Verdict: A sound Kaching or Pumper alternative if you want the urgency widgets included.

11. Simple Bundles & Kits (best for inventory tracking, 3PL and Shopify Plus)

• Rating: 4.9 ★ (803 reviews), Built for Shopify, launched March 16, 2021
• Price: Free (3 bundles, 50 monthly orders). Basic $14/mo, Grow & Advanced $39/mo, Plus $149/mo. Annual billing saves 17%.
• Best for: Brands that ship through a 3PL, warehouse management system or ERP.

Pros: Simple Bundles breaks bundle orders into component SKUs and syncs inventory across fulfillment systems. It supports multipacks, mix and match, build-a-box, subscription and wholesale bundles, and lists integrations with Shopify Flow, Shopify POS, ShipStation, Hydrogen and Amazon via Codisto. Plans are flat, not revenue-based.

Cons: Storefront widgets are plainer than the conversion-focused apps. Shopify Flow, advanced rules and unlimited POS locations need the $39 plan, and Hydrogen support needs the $149 Plus plan.

Verdict: The default choice whenever fulfillment accuracy matters more than widget design.

12. Unlimited Bundles & Discounts, by Revy

• Rating: 4.8 ★ (722 reviews), Built for Shopify, launched October 19, 2018
• Price: Free up to $100 in monthly bundle sales. Starter $9.99/mo (up to $1,000), Growth $29.99/mo (up to $10,000), Unlimited $49.99/mo. 7-day trial.
• Best for: Stores that want several automatic discounts to stack.

Pros: Unlimited Bundles & Discounts covers volume breaks, mix and match, Buy X Get Y, free gifts and free shipping offers, with a live preview editor and Shopify POS support.

Cons: 14% of its reviews are four stars or lower. No builder page.

Verdict: A long-running, fairly priced generalist that appears on Shopify's own list.

13. Rebolt Upsell & Bundles App

• Rating: 4.8 ★ (585 reviews), launched July 16, 2018. No Built for Shopify badge on the listing.
• Price: Free until $300 of bundle revenue. Growth $19.99/mo with a 7-day trial. Custom Solution $299/mo including development work.
• Best for: Bundles, checkout add-ons and post-purchase offers on one flat plan.

Pros: Rebolt lists combo and BOGO bundles, mix and match, build-a-box, frequently bought together, free gifts, A/B testing and analytics, all on the single $19.99 plan.

Cons: No badge, and a smaller review base than the leaders. Test it on your theme first.

Verdict: Predictable pricing for a broad feature list.

14. Amplify | Bundles & Upsell, formerly PickyStory

• Rating: 4.5 ★ (537 reviews), launched March 28, 2019. No Built for Shopify badge on the listing.
• Price: "Pay as You Grow" from $99.50/mo for stores with up to $30,000 in total monthly revenue, rising with store volume. 30-day trial.
• Best for: Established stores that want AI-personalized offers across product page, cart and checkout.

Pros: Amplify offers bundle-as-product, a bundle builder, quantity breaks, BOGO, shop-the-look and connected cart and checkout upsells, with a 30-day trial, the joint longest here alongside Zoorix.

Cons: The highest entry price and the lowest rating of any third-party app on this page. Pricing is tied to total store revenue, not bundle revenue. Read the most recent reviews on the listing before you commit.

Verdict: Only worth pricing up if you will use the whole funnel.

15. FoxSell Bundle Builder (best for mix and match on complex catalogs)

• Rating: 5.0 ★ (95 reviews), Built for Shopify, launched November 6, 2023
• Price: Starter free up to $1,000 a month in bundle sales. Pro $49/mo (up to $5,000), Scale $149/mo (up to $15,000), Growth $249/mo (up to $25,000). 14-day trial.
• Best for: Build-your-own-box stores with many variants.

Pros: FoxSell lists bundles with infinite variants, automated inventory sync, multipacks, add-ons and free gifts. Its free tier has the highest ceiling of any capped plan here.

Cons: Paid tiers are the most expensive per dollar of bundle sales, and the review base is small.

Verdict: Excellent for a BYOB-led store while it stays under $1,000 a month in bundle sales. Model the cost beyond that.

16. Easy Bundles: Bundle Builder (best guided build-a-box flow)

• Rating: 4.9 ★ (1,405 reviews), Built for Shopify, launched September 15, 2022
• Price: Free up to $500 a month in bundle sales. Essential $29/mo (up to $3,000), Growth $49/mo (up to $5,000), Scale $99/mo (up to $10,000). 15-day trial on paid plans.
• Best for: Gift boxes and step-by-step build-your-own-bundle pages.

Pros: Easy Bundles, by Skai Lama, ranked fourth in the App Store's bundles category on October 11, 2026. It lists single and multi-step builders, fixed and mix-and-match bundles, quantity breaks, subscription bundles, add-ons and free gifts, and says it works with Shopify POS, 3PLs, side-cart apps and subscription apps.

Cons: The free plan covers mix and match, fixed and volume bundles but not the builders, which start on the $29 plan. Add-ons, free gifts and subscription bundles need the $49 plan, and published tiers stop at $10,000 a month in bundle sales.

Verdict: A strong builder-first choice with real review volume. Price it against FoxSell at your expected bundle revenue, and against Oxify's flat $14.99/mo.

17. Moon Bundles CartDrawer Upsell (best bundles plus cart drawer)

• Rating: 5.0 ★ (652 reviews), Built for Shopify, launched June 7, 2024
• Price: Free up to $500 of generated revenue. Essential $19.99/mo (up to $2,000), Pro $39.99/mo (up to $10,000), Premium $79.99/mo (unlimited). 7-day trial on paid plans.
• Best for: Stores that want bundles, a cart drawer and post-purchase upsells from one developer.

Pros: Moon Bundles lists the same features on every plan, including the free one: quantity breaks, mix and match with a bundle builder, fixed bundles, add-on upsells, post-purchase offers and its own cart drawer. The Premium tier caps the bill at $79.99.

Cons: A younger app than the leaders, and no SKU breakdown for 3PLs. If you already run a cart drawer app, you are paying for overlap.

Verdict: One of the more generous free tiers here, and worth a look if you have no cart drawer yet.

18. Zoorix: Bundles & Cross Sell (cheapest paid tiers for small stores)

• Rating: 4.9 ★ (391 reviews), launched December 17, 2019. No Built for Shopify badge on the listing.
• Price: Forever Free plan with app branding. Basic $7.99/mo ($100 to $200 of revenue generated through Zoorix), Growth $14.99/mo ($200 to $400), Premium $29.99/mo ($400 to $800). 30-day trial on paid plans.
• Best for: Small stores that want cross-sell bundles, volume discounts and a cart drawer at a low entry price.

Pros: Zoorix appears on more competing roundups than any other app we had not covered. Every plan lists the same features: cross-sell bundles, volume discounts, mix and match, product recommendations and a cart drawer. The 30-day trial is long.

Cons: The revenue bands are narrow, so $29.99 covers only $400 to $800 of attributed revenue, which is expensive per dollar next to Rapid Bundles or Pumper. The main listing does not show what happens above $800, so ask before you scale. No badge and no builder page.

Verdict: Fine for a small catalog testing cross-sells. Check the cost curve before a busy season.

19. Bundlex Product Bundles Upsell (free visual bundle widget)

• Rating: 5.0 ★ (162 reviews), Built for Shopify, launched October 21, 2024
• Price: Free. No paid plans are listed.
• Best for: Product-page bundles where each item needs its own image, swatch and variant picker.

Pros: Bundlex ranked third in the App Store's bundles category on October 11, 2026. It lists bundles, BOGO, quantity breaks and cross-sell offers in one visual widget, plus a countdown timer, sticky add to cart, low-stock alerts and AI translation, and says it works with GemPages, PageFly and Shogun.

Cons: The smallest review base after ours and FoxSell's, and under two years on the App Store. As with AOV.ai, a free app can add pricing later. No dedicated builder page is advertised.

Verdict: A second genuinely free option beside AOV.ai. Re-check its pricing section before you depend on it.

20. Shopify Bundles (free and native)

• Rating: 2.8 ★ (572 reviews), made by Shopify, launched July 11, 2023
• Price: Free.
• Best for: One or two fixed bundles or multipacks on a new store.

Pros: Shopify Bundles builds fixed bundles and multipacks inside the admin. Availability is calculated from the component with the lowest stock, so you will not oversell a kit.

Cons: 23% of its reviews are one star. Shopify's own documentation says bundles cannot be used with subscriptions or other purchase options, cannot be nested, cannot be exchanged, do not support import, export or bulk editing, and that a bundle has to be deleted and recreated if a component SKU changes. Mix and match is left to third-party apps. There are no quantity breaks and no analytics.

Verdict: Fine for a first kit. Most stores that take bundling seriously move on.

Shopify bundle apps: price vs features

This matrix shows which formats each app advertises on its listing, next to its entry price for a live store.

✓ means the feature is advertised on the app's listing. — means it is not advertised, so confirm with the developer if it matters. "Upsell bundles" covers frequently bought together, cross-sell or post-purchase bundle offers.

Alternatives to the Shopify Bundles app

Merchants usually look for alternatives to the Shopify Bundles app for one of four reasons. Here is the fix for each.

• You need mix and match or a bundle-builder page. The native app only does fixed bundles and multipacks. Use Oxify, FoxSell, AOV.ai (free) or Bundler Premium ($9.99/mo).
• You need discounts shown on the product page. The native app has no quantity breaks. Kaching, Pumper and Oxify show tiered pricing and apply it automatically.
• You sell subscriptions or wholesale. Native bundles cannot be combined with purchase options. Simple Bundles & Kits, Kaching and Rapid Bundles list subscription bundles.
• Your 3PL needs component SKUs, or you edit bundles in bulk. Use Simple Bundles & Kits, which supports bulk import from its $14 plan.

If you want to stay free, AOV.ai Bundles Quantity Breaks and Bundler are the two free replacements that do more than the native app.

Alternatives to the Bundler app

Bundler (4.9 ★, 2,722 reviews) is hard to beat on price, so people usually leave it for features. For analytics without the $19.99 Executive plan, or for A/B testing, look at Oxify or Kaching. For a free builder page, use AOV.ai. For post-purchase upsells, use Rapid Bundles (free up to $100/mo). For component-level fulfillment, use Simple Bundles & Kits. For gift-with-purchase campaigns, use BOGOS.

Best Fast Bundle alternatives

Interest in Fast Bundle alternatives rose after the app was pulled from the App Store on July 18, 2026. It has been reinstated (5.0 ★, 3,539 reviews, $19 to $139/mo), but it has no free plan for live stores and no longer shows a Built for Shopify badge. The closest alternatives by reason for switching:

• Same breadth of bundle types: Oxify ($14.99/mo flat, 14-day trial) or Rebolt (free to $300, then a flat $19.99).
• More review evidence: Kaching Bundles (6,264 reviews) or BOGOS (4,474).
• Cheaper at the $3,000 to $10,000 level: Rapid Bundles Pro covers up to $10,000 for $29/mo, against Fast Bundle's $139.
• Entirely free: AOV.ai, which also offers frequently bought together.
• Inventory and 3PL: Simple Bundles & Kits.

Our dedicated Kaching Bundles alternatives post covers that app in the same way.

Best free bundle apps for Shopify: what "free" really means

The best free bundle app for Shopify is AOV.ai if you want a builder page and Bundler if you want proven volume discounts with no revenue meter. Revenue-capped free plans are still useful: they let you prove that bundles lift order value before you pay.

Best bundle app for Shopify with inventory tracking and 3PL sync

Simple Bundles & Kits (4.9 ★, 803 reviews) is the clear pick. It breaks bundle orders into component SKUs and syncs stock with 3PL, WMS and fulfillment systems, and it works with Shopify Flow and ShipStation. FoxSell also advertises automated inventory sync for builder bundles. Shopify's native app calculates availability from the lowest-stock component but only for fixed bundles. Cart-transform apps such as Oxify deduct stock from the real component products, which is enough for stores that fulfill in-house. If a warehouse picks your orders, ask any app one question before installing: "What line items will my 3PL see on a bundle order?"

Best build-your-own-bundle and mix-and-match apps (bundle builder pages)

A bundle builder page lets shoppers fill a box step by step, often with a progress bar and tiered discounts. The apps that advertise a dedicated builder are Oxify, FoxSell, AOV.ai, Fast Bundle, Simple Bundles, Rebolt, Amplify, Easy Bundles ($29 plan and up), Moon Bundles, BOGOS (Basic plan and up) and Bundler (custom landing pages on Premium). Choose FoxSell for very large variant counts, AOV.ai for zero cost, Simple Bundles if the boxes ship from a warehouse, and Oxify if you want the builder alongside quantity breaks and BOGO. Our mix-and-match bundle apps roundup goes deeper.

Best bundle app for volume discounts, kits and discount settings

Quantity breaks and volume discounts are the same mechanism: the unit price falls as the shopper buys more of one product, for example 10% off two and 15% off three. Apps use the two terms interchangeably, and some also say tiered pricing. For volume discounts on a single product page, Pumper (capped at $49.99/mo), Kaching and Oxify are the specialists, and Bundler does it free. For kits, meaning a fixed set sold as one product, use Simple Bundles & Kits or the native Shopify Bundles app. The discount settings worth checking on any app are: percentage, fixed amount and fixed price per tier; whether discounts apply automatically without a code; whether they combine with your own discount codes; and whether you can exclude products or schedule start and end dates. Unlimited Bundles & Discounts is built around stacking several automatic discounts. See our quantity breaks apps comparison and the bundle pricing strategy guide.

Which Shopify bundle apps support upsell bundles?

Frequently bought together blocks are advertised by Kaching, BOGOS, Fast Bundle (AI-suggested), AOV.ai, Simple Bundles and Rebolt. Post-purchase bundle offers are advertised by Rapid Bundles, Koala, Rebolt and Amplify; checkout upsells by BOGOS (Plus plan) and Amplify. For in-cart offers, pair a bundle app with a cart drawer.

Best product bundle app for Shopify Plus stores

Plus stores should weigh three things: fulfillment-grade inventory handling, support for headless and POS, and how the bill behaves at volume. Simple Bundles & Kits is our Plus pick: the $149/mo Plus plan adds Hydrogen support, a dedicated queue and 24/7 priority support, and the price does not rise with revenue. BOGOS Plus ($109.99/mo, 2,000 orders included) suits promotion-heavy Plus brands on POS or Hydrogen and adds checkout upsells. Kaching lists Hydrogen and POS support too, but its top published tier covers only $10,000 of attributed revenue, so ask for a quote above that. Oxify has a single flat $14.99/mo plan with no revenue tiers. Shopify also lets Plus stores build custom bundles directly on the Cart Transform API if you have developers.

Best bundling app for Black Friday on Shopify

For BFCM you need scheduling, a predictable bill and enough lead time to test. Apps with a flat or capped price are safest in a record month: Bundler ($19.99 maximum), Pumper ($49.99 Unlimited), Rapid Bundles ($59 Elite) and Simple Bundles (flat plans). Order-metered pricing such as BOGOS's $0.05 overage, and low revenue caps such as Kaching's $10,000 Pro tier, are the ones to model first. Oxify and Kaching both include A/B testing, so you can settle the winning offer in October. Install early, never in the week of the sale, and add a countdown timer for urgency. The full calendar is in our Black Friday bundle playbook.

Best Shopify bundle apps to increase AOV

Evidence first. In a published case study, Shopify Plus agency Swanky reported that a bundle builder on DockATot's store produced a 55% increase in AOV and an 86% increase in revenue per user. That is one store, so treat it as a ceiling, not a forecast. Research from Harvard Business School on Nintendo's console bundles also found that mixed bundling, where items are sold both together and separately, outperformed bundle-only selling. Keep the single items available.

The formats that move AOV most directly are quantity breaks on a hero product (Pumper, Kaching, Oxify), a builder with tiered rewards such as "pick 4, save 15%" (Oxify, FoxSell, AOV.ai), and gift thresholds (BOGOS). Shopify's product bundling guide and our post on how many quantity break tiers to use cover the pricing side.

Product bundling on Shopify vs WooCommerce, BigCommerce, Magento and other platforms

If you are evaluating e-commerce platforms partly on bundling, this is how they compare. Shopify's approach is a free first-party app plus a large app market built on a shared API. Others build bundling into the core product model or leave it to extensions.

The practical difference is speed and cost. On Shopify, a merchant can install a bundle app, often on a free plan, and launch mix and match, quantity breaks or a builder page in an afternoon without a developer. Magento and Salesforce have stronger native bundle data models, but anything beyond them is a development project. Check each platform's current documentation before you decide, because these capabilities change.

How to create a bundle on Shopify (free, with the native app)

If you only need a fixed kit or a multipack, you can do it today without paying anything.

1. Install the free Shopify Bundles app from the App Store.
2. In your Shopify admin, open the app and choose to create a bundle.
3. Select the products that go into the bundle and set the quantity of each. For a multipack, pick one product and raise the quantity.
4. Choose which options, such as size or color, the shopper can pick.
5. Save. Shopify creates the bundle as a product. Set its price (normally below the sum of the parts), add images and a description, and publish it to your sales channels.
6. Place a test order and check that stock was deducted from each component.

Read Shopify's eligibility and considerations page first, because some stores and checkout setups are not supported. For quantity breaks, mix and match or a builder page, the steps are the same in any third-party app: install, pick the products, set the discount tiers, add the app's block in the theme editor, then test at checkout with and without a discount code. The easiest bundle app to set up for a fixed kit is the native Shopify Bundles app, because it lives in the admin and needs no theme changes. Among third-party apps, those built on theme app blocks install without editing theme code, but we have not timed setup for every app, so try the free plan or trial on a duplicate theme first.

What merchants say about bundle apps

Reddit's r/shopify thread "Best Bundling Apps?" ranks second for this search, but Reddit blocks automated access, so we could not read it for this update and will not guess at its contents. The same question was asked in the Shopify Community thread "Best Bundling Apps?" in late August 2026, and the pattern there is worth knowing before you ask for recommendations anywhere.

• The complaints are about inventory and orders, not widgets. The merchant who started the thread wanted to leave Shopify's native app because bundles kept a separate stock pool, were not applied automatically when the items were already in the cart, and made orders harder to edit.
• The useful advice was a distinction, not an app name. Replies separated "bundle products" (a new product or SKU, which creates the inventory headaches) from "discount-based bundles" (the ordinary products stay in the cart and a discount is applied automatically). That is the same split we describe under cart-transform vs variant-based bundles.
• Most app recommendations came from the apps' own staff. Several replies were posted by people whose usernames carry the app's name, and other members complained about AI-written answers. Treat forum recommendations as leads, then check the listing's recent one-star and two-star reviews yourself.
