Best Fast Bundle alternatives reviewed in 2026
Short answer: It depends on why you're leaving Fast Bundle. When your packing team or 3PL needs to see what's inside each bundle, choose Simple Bundles, with a free plan and paid plans from $14/month. When your bill jumps every time bundle sales grow, choose Bundler, which is free and then a flat $9.99/month. When you'd like to remove other app bills as well, choose Vitals at $29.99/month, because it includes product bundles and 40+ other apps in a single subscription. When you want several offer types at no cost, choose AOV.ai Bundles, which lists only a free plan.
Fast Bundle is a popular product bundles app that has offered fixed bundles, mix and match and a build-a-box builder on Shopify since 2020, and merchants keep praising the 24/7 chat team that sets up offers for them. But at $19/month for the first $1,000 of bundle sales, it has the second-highest starting price of these apps and no free plan for live stores, and one recent reviewer says discounts stopped applying and each sale launch needed hours of fixes.
So I installed 8 Fast Bundle alternatives on a test store. Below, you'll find what each one is built for, what it costs as of November 2026 and what you'd give up by moving.
Why do merchants look for a Fast Bundle alternative?
Reliability is the main reason, because recent reviews describe bundles that stopped working on live stores. The price at higher bundle sales comes next, followed by orders that don't show up as bundles.
Bundles have failed when stores needed them. In recent reviews from May to August 2026, one merchant says discounts stopped applying and each sale launch needed hours of troubleshooting, and another rebuilt every bundle over a weekend after the app left the App Store. Fast Bundle's status page says Shopify removed the app after a security attack in July 2026 and restored it fully on 3 August. I didn't find a removal like that on any of the 8 alternatives, but Pumper, Kaching and Simple Bundles have their own reports of offer or stock errors.
The bill climbs quickly as bundle sales grow. Fast Bundle costs $49/month up to $3,000 of monthly bundle sales and $139/month up to $10,000, so a store at $3,500 pays nearly 3 times as much as a store at $3,000. A reviewer in November 2025 also says restricted tools and slower support made the lower paid plans poor value. Bundler charges a flat fee, and Unlimited Bundles and Pumper stop at $49.99/month. Vitals has one plan at $29.99/month, and it doesn't charge by bundle revenue.
Some bundle orders don't show up as bundles. One merchant said in November 2025 that orders and analytics showed no sign of a bundle, so Christmas gift sets ended up packed loose. Support fixed some of the problems, but that merchant still left. Simple Bundles breaks every bundle into component SKUs for the warehouse, and Vitals lists each bundled product as its own line item.
These come from 27 of the 3,545 reviews Fast Bundle had in October 2026, so most merchants don't report them.
Which Fast Bundle alternatives made my shortlist?
I selected apps that do the same job as Fast Bundle, with a rating of 4.8 or higher and at least one merchant review from September 2026 or later.These 8 alternatives made my shortlist:
- Vitals: an all-in-one app with product bundles and 40+ other apps in a single subscription
- AOV.ai Bundles: 6 offer types on a free listed plan
- Kaching Bundles: A/B tests on every plan and a lower price at $10,000 of sales
- Frequently Bought Together (CBB): automatic pairings with a price that stops at $39.99/month
- Simple Bundles: component SKUs on every order for packing teams and 3PLs
- Pumper Bundles: quantity tiers that can carry a free gift or BOGO deal
- Unlimited Bundles & Discounts: build-your-own pages and offers that change by customer
- Bundler: a flat fee with no revenue limit
I've put each app's rating, starting price and how it charges in this table, with Fast Bundle first as the baseline:
| App | Rating | Starting price | Charges by |
|---|---|---|---|
| Fast Bundle | 5.0 from 3,639 reviews | $19/month | Bundle sales |
| Vitals | 4.9 from 2,974 reviews | $29.99/month | Fixed Price |
| AOV.ai Bundles | 5.0 from 1,701 reviews | Free | No paid plan listed |
| Kaching Bundles | 5.0 from 6,625 reviews | $14.99/month | Added revenue |
| Frequently Bought Together (CBB) | 4.9 from 1,213 reviews | Free, then $9.99/month | Orders |
| Simple Bundles | 4.9 from 826 reviews | Free, then $14/month | Shopify plan and orders |
| Pumper Bundles | 4.9 from 3,632 reviews | Free, then $9.99/month | Added revenue |
| Unlimited Bundles & Discounts | 4.8 from 727 reviews | Free, then $9.99/month | Bundle sales |
| Bundler | 4.9 from 2,779 reviews | Free, then $9.99/month | A flat fee |
Prices as of November 2026. Developers change them, so check each listing before you choose.
When your bundle sales are above $3,000 a month, compare Bundler, Pumper and Unlimited Bundles first.
How did I review these Fast Bundle alternatives?
I installed each app on a test store, then went through each App Store listing, every plan and the newest and lowest-rated merchant reviews. I used Fast Bundle as the baseline for each comparison.
I looked at these details for each app:
- Offer types: which bundles I could build, including build-a-box, mix and match and quantity breaks
- Bundle products: whether a bundle can exist as its own Shopify product or only as a discount on existing ones
- Placement: where offers appear, from the product page to the cart and thank-you page
- Orders: how a bundle reads on the order for whoever packs it
- AI features: what AI does in each app, such as pairing products or writing an offer
- Integrations: which subscription, cart and page builder apps it names
- Setup: how long each app needed before my first offer was live
- Design: whether each offer matched my theme and stayed responsive on my test store
- Speed: whether one more app matters when many stores already have 10 to 15 installed
- Pricing: how each app charges, its plan limits and what each plan includes
- Reviews: what the newest and lowest-rated App Store reviews say, including about support
- Moving: what you can bring across from Fast Bundle, such as bundle products and builder setups
Vitals is first because it brings product bundles and 40+ other apps together in one subscription, and I put the other 7 in random order.
I don't give speed scores, because they depend on your theme and your other apps. Test on your own store instead, and all 8 of these apps have a free plan or trial.
What did I find when I compared them with Fast Bundle?
These alternatives fall into 3 groups: bundle and quantity break apps (AOV.ai Bundles, Kaching, Pumper, Unlimited Bundles, Bundler), specialists in one part of the job (Frequently Bought Together for pairings, Simple Bundles for fulfilment) and an all-in-one app (Vitals). Some only offer bundles and others include more apps, and I liked the ones with more, because I'd need fewer separate apps.
I found 6 main differences from Fast Bundle.The apps differ on which ones they include, so check which you need before you compare prices:
- How the bill grows: Fast Bundle moves from $19/month to $139/month at $10,000 of bundle sales, then to $299/month. Bundler stays flat, Frequently Bought Together stops at $39.99/month, and Pumper and Unlimited Bundles stop at $49.99/month. Kaching also reaches $299/month, but only above $50,000 of added revenue.
- Build-a-box offers: Fast Bundle includes its Bundle Builder on every paid plan. AOV.ai Bundles, Simple Bundles and Unlimited Bundles offer a builder or a build-your-own page, and Frequently Bought Together has neither.
- Bundles as products: Fast Bundle can make a bundle its own Shopify product with a URL and SKU. Simple Bundles does this for every bundle, and AOV.ai Bundles does it for fixed bundles. Bundler, Pumper and Vitals discount the products you already have.
- Placement: Fast Bundle offers the product page, a cart drawer and pop-ups. Vitals goes further with 5 placements that end on the thank-you page, while AOV.ai Bundles and Kaching sell their cart drawers as separate apps.
- A/B testing: Fast Bundle lists it, and so does Kaching on every plan. I couldn't find it on the remaining 7.
- Free plans: Fast Bundle is only free on development stores. Bundler's free plan has no revenue limit, Pumper stops at $300, Unlimited Bundles at $100, Simple Bundles at 50 monthly orders and Frequently Bought Together at 3 manual bundles. AOV.ai Bundles lists only a free plan, and Vitals and Kaching offer trials.
I also found these differences in how the apps work:
- Reports: Fast Bundle shows recommendation performance and optimisation suggestions. Kaching adds CSV exports, Pumper compares average order value before and after, and Simple Bundles shows conversion and order value on every plan. Bundler keeps its graphs for Executive.
- AI features: Fast Bundle pairs products with AI, generates bundle images and writes titles and descriptions for bundle products. Vitals drafts a bundle from a plain-language prompt, and with Vitals MCP, you can do everything in Vitals with Claude or ChatGPT. AOV.ai Bundles has an MCP connection that creates and edits offers, Kaching's listing images show an assistant called Ching, Simple Bundles has Bundle Magic AI and Frequently Bought Together has AI recommendations. Pumper only lists AI translations, and I found nothing on Unlimited Bundles or Bundler.
- Setup: almost every app took me 2 to 5 minutes, so setup time shouldn't decide this.
- Design: on my test store, almost all of them responded well, felt user friendly and offered plenty of customisation.
- Speed: a bundle app on its own didn't hurt page speed for me. The load builds as you add reviews, discounts, gifts and visitor recordings, so I'd worry more about how many apps a store has than about which bundle app it picks.
What are the best Fast Bundle alternatives?
Vitals is my top pick for merchants leaving Fast Bundle who pay for other apps too, because it includes product bundles and 40+ other apps in one subscription. AOV.ai Bundles comes next for stores that want several offer types on a free listing. The other 6 suit A/B testing, automatic pairings, warehouse fulfilment, gifts inside quantity tiers, customer-based offers and a flat fee.
1. Vitals: Best for adding bundles to 40+ other apps on one bill

Vitals is an all-in-one Shopify app, and its Product Bundles app is one of 40+ apps in one subscription. I'd choose it when Fast Bundle is one of many apps you'd like to stop paying for.
Why I like this app:
What I liked first in Vitals was how a bundle reads on the order, because each product arrives as its own line item with its stock tracked in Shopify. Shoppers can also use a Pick another button to change a product in the bundle. Then there are the 40+ other apps, such as reviews, email and visitor recordings, so you don't have to install and pay for each one separately. With Vitals MCP, you can do everything in Vitals with Claude or ChatGPT.
Compared with Fast Bundle:
Vitals shows every bundled product on the order, which answers the loose-packing report, and it adds thank-you page placement that I didn't find on Fast Bundle. You'd give up the Bundle Builder, A/B testing and bundles sold as their own products. Vitals has no free plan, and its $29.99/month is the highest starting price in this comparison.
Features:
- Fixed and mix-and-match bundles
- Frequently bought together and same-collection bundles
- Multi-pack bundles
- A bundle created by AI from a typed prompt
- A separate size and colour dropdown for each product
- Each bundled product as its own line item
- Product page, Add to Cart pop-up, cart, Checkout pop-up and thank-you page placements
- 3 layouts and 9 colour presets, or your own CSS
- Start and end dates, a countdown and country targeting
- Volume Discounts and Free Gifts apps in the same subscription
- 40+ apps in the same subscription
Pricing: Vitals has one plan, with all 40+ apps included:
- All in one plan: $29.99/month
- Trial: 7 days
Reviews: Vitals has 4.9 stars from 2,974 reviews on the Shopify App Store. A merchant of over 6 years praised its customer support in November 2026, and another says the many apps are simple and effective. The main criticism I found is from February 2026, when a merchant of almost 5 years couldn't reach the team after several attempts. Vitals' reply says it followed up by email and Instagram.
Best for: A store that wants to cancel Fast Bundle along with its separate reviews, email or recordings apps.
I wouldn't choose it if: Shoppers need to fill a large box, because a Vitals bundle holds 2 to 5 products. AOV.ai Bundles offers Bundle Builder pages.
See Vitals on the Shopify App Store
2. AOV.ai Bundles: Best for several offer types with no listed fee

AOV.ai Bundles is a quantity break and bundle app with 6 offer types in one install. Choose it when you want Fast Bundle's range of offers on the product page without a monthly fee.
Why I like this app:
The free listing drew me to AOV.ai, because all 6 offer types, from volume tiers to Bundle Builder pages, come on its only listed plan. I also liked its MCP connection, since Claude or ChatGPT could create and edit offers for me, and new ones start switched off until I'm happy with them. Recent reviewers say live chat customises the widget to match their theme.
Compared with Fast Bundle:
AOV.ai Bundles shows no fee on its listing, against $19/month for Fast Bundle's first $1,000 of bundle sales, and it has the Built for Shopify badge. You'd give up A/B testing, AI pairings and the cart drawer, which AOV.ai sells as a separate app. Its docs mention a free-plan revenue limit that can pause bundles without saying what the limit is, so ask support before you rely on it.
Features:
- Volume discount tiers
- Frequently bought together offers
- Mix and match
- Bundle Builder pages
- Fixed bundles with variants and multipacks
- Related product recommendations on the product page
- Shopify Markets, schedules and bulk offer editing
- Customer segments and maximum uses on some offer types
- MCP for Claude, ChatGPT, Gemini and Grok
- AOV.ai Cart Drawer, EComposer, GemPages and Avada Joy Subscription
I didn't find any AI features in it, apart from its MCP connection.
Pricing: AOV.ai Bundles lists one plan on the App Store:
- Free: all 6 offer types
- Trial: none listed
Reviews: AOV.ai Bundles has 5.0 stars from 1,701 reviews on the Shopify App Store. Recent reviewers praise an intuitive interface and fast help on chat. Others say discounts wouldn't apply until they had both the app block and the app embed in their theme.
Best for: A store that wants frequently bought together, volume tiers and builder pages at no listed cost.
I wouldn't choose it if: You sell from collection or landing pages, because one June 2026 reviewer says the app disabled Add to Cart buttons away from product pages. Bundler creates landing pages on Premium.
See AOV.ai Bundles on the Shopify App Store
3. Kaching Bundles: Best for testing quantity break offers against each other

Kaching Bundles is a product page bundle app built around quantity breaks and BOGO offers. It makes more sense when you already run A/B tests and want them at a lower price.
Why I like this app:
A/B testing is the reason I'd look at Kaching, because it compares bundle combinations and discount types on every plan. That gives a small store the same testing as a large one. I also found the drag-and-drop builder easy to match to my store's colours. When I read the newest reviews, one merchant thanked an agent for sending screen recordings of exactly what to do.
Compared with Fast Bundle:
Kaching costs $59.99/month up to $10,000 where Fast Bundle costs $139/month, though Kaching counts added revenue instead of bundle sales. You'd give up the Bundle Builder and a built-in cart drawer, because Kaching sells its cart drawer and post-purchase upsells as separate apps. One merchant reported in August 2026 that more than 100 orders went out with the wrong size in their bundles, and Kaching replied that a custom variant picker caused it.
Features:
- Quantity breaks by percentage, dollar amount or set price
- BOGO and Buy X Get Y
- Mix and match and collection-based volume discounts, shown on its listing image
- Progressive free gifts
- Checkbox upsells
- Bundle subscriptions and urgency timers
- A/B testing on every plan
- Analytics with CSV export
- Ching, an AI assistant connected to Claude and ChatGPT, shown on its listing image
- Hydrogen, PageFly, GemPages, EComposer, Instant and UpCart
- Shopify POS and Shopify Flow
Pricing: Kaching Bundles charges by the added revenue its offers bring in:
- Starter: $14.99/month, up to $1,000
- Scale: $29.99/month, up to $5,000
- Pro: $59.99/month, up to $10,000
- Up to $20,000: $99/month
- Up to $30,000: $149/month
- Up to $50,000: $199/month
- Over $50,000: $299/month
- Trial: 7 days
Its plans above $10,000 appear on its website pricing slider, and not on the App Store listing.
Reviews: Kaching Bundles has 5.0 stars from 6,625 reviews on the Shopify App Store. Recent reviewers name agents who found and fixed problems inside their accounts. One August 2026 reviewer who used to love the app now reports long waits and ignored follow-up questions.
Best for: A store that wants to learn which discount or layout sells best before it commits.
I wouldn't choose it if: Your offers bring in more than $50,000 a month, because $299/month is a lot for quantity breaks. Pumper's Unlimited plan costs $49.99/month at any level of added revenue.
See Kaching Bundles on the Shopify App Store
4. Frequently Bought Together (CBB): Best for automatic pairings on a large catalogue

Frequently Bought Together (CBB) is a recommendation app that shows Amazon-style bundles with a one-click add to cart. I'd choose it when pairings are the only part of Fast Bundle you use.
Why I like this app:
Automatic pairings won me over here. I could leave recommendations to past purchases and then overrule them by hand on the products that matter most, so a long catalogue didn't need setting up one product at a time. I also like that star ratings from apps such as Judge.me and Loox appear inside the widget. One reviewer with more than 6 years on the app still calls it great.
Compared with Fast Bundle:
Frequently Bought Together stops at $39.99/month however many orders you get, while Fast Bundle's AI pairings come with a bill that reaches $299/month. The cost is every other offer type, including the Bundle Builder, quantity breaks and BOGO. It recommends products you already sell, so it won't create bundle products or SKUs.
Features:
- AI recommendations from past purchases
- Manual and global recommendations
- Percentage, fixed, free item and free shipping discounts
- Star ratings from Judge.me, Loox, Yotpo, Stamped.io, Ryviu, Ali Reviews and Opinew
- Product exclusions and a limit on recommendations shown
- Choice of what happens after add to cart
- Shopify Markets and translations
- Analytics on paid plans
Pricing: Frequently Bought Together charges by monthly orders:
- Free: Starter, 3 manual bundles
- Professional I: $9.99/month, up to 50 orders
- Professional II: $24.99/month, up to 500 orders
- Professional III: $39.99/month, 500+ orders
- Trial: 14 days
Its listing shows the widget on product and cart pages, but a developer reply from March 2026 points to its separate Also Bought app for the cart, so check this in the app.
Reviews: Frequently Bought Together (CBB) has 4.9 stars from 1,213 reviews on the Shopify App Store. Long-term reviewers praise its service. Others found manual bundles hard to create, and the developer offers to build them for you.
Best for: A store with a long catalogue and enough order history for automatic recommendations.
I wouldn't choose it if: Your store is new and has few past orders, because the automatic recommendations learn from purchases. AOV.ai Bundles has manual offers at no listed cost.
See Frequently Bought Together (CBB) on the Shopify App Store
5. Simple Bundles: Best for kits that reach the warehouse as component SKUs

Simple Bundles is a bundles and kits app that turns each bundle into its component SKUs at checkout. It makes more sense when a bundle has to arrive at your packing team or 3PL item by item.
Why I like this app:
Component tracking is where Simple Bundles won me over. Bundle stock follows the lowest-stocked item, and the order shows every child SKU, so a picker can see exactly what goes in the box. Its Infinite Options bundles also get past Shopify's variant limit. One recent reviewer says bundles sync with TikTok, which they say can be hard.
Compared with Fast Bundle:
Simple Bundles goes furthest on the packing problem, because every order carries its component SKUs, and each bundle is a real product, as it can be on Fast Bundle. The trade-off is A/B testing and the cart drawer, and one reviewer says build-your-own bundles only accept percentage discounts. Its fees follow your Shopify plan and every store order over a rolling 90 days, so a store above 50 monthly orders won't qualify for the free plan.
Features:
- Fixed bundles, kits and multipacks
- Mix and match and build-your-own boxes
- BOGO and volume discounts
- Infinite Options beyond Shopify's variant limit
- Single-SKU and multi-SKU bundles
- Automatic SKU breakdown for fulfilment
- Inventory sync by component
- Bundle Magic AI, from order history or a typed description
- Bundle sales, conversion and order value analytics
- ShipStation, Recharge, Seal, Appstle, Loop and Klaviyo
- Shopify POS, Shopify Flow and Hydrogen on set plans
Pricing: Simple Bundles charges by your Shopify plan and order volume:
- Free: 3 bundles and 50 monthly orders
- Basic: $24/month, or $14/month under 100 monthly orders
- Grow & Advanced: $39/month
- Plus: $149/month
- Trial: none listed
Reviews: Simple Bundles has 4.9 stars from 826 reviews on the Shopify App Store. Recent reviewers thank support for setting up sample sets and multi-SKU bundles. One July 2026 reviewer says there's no select-all when adding products, so a single bundle needed an hour, and the developer accepted the point.
Best for: A store whose 3PL or packing team has to see every item in a kit.
I wouldn't choose it if: Your team wants the app's admin in a language other than English, because the developer confirmed in October 2025 that it's English only. Bundler lists 17 languages.
See Simple Bundles on the Shopify App Store
6. Pumper Bundles: Best for free gifts and BOGO inside quantity tiers

Pumper Bundles is a quantity break app that shows offers above Add to Cart. Choose it when most of your Fast Bundle sales come from buying more of one product.
Why I like this app:
Pumper's tiers are more flexible than I expected, because a free gift or a BOGO deal can be part of a quantity break. Discounts can run per unit, as a percentage or as a flat amount. Its reports break revenue down by offer type, so I could see which tier was doing the work. Recent reviewers thank named chat agents, and one got help within minutes.
Compared with Fast Bundle:
Pumper's Unlimited plan costs $49.99/month at any level of added revenue, where Fast Bundle reaches $139/month at $10,000 of bundle sales. You'd give up AI pairings, A/B testing and a cart drawer of its own, because Pumper relies on apps such as Upcart and Monster Cart. One reviewer says a best-selling offer switched off when the store passed a plan limit.
Features:
- Quantity breaks by unit, percentage or flat amount
- Free gifts and BOGO inside quantity tiers
- Fixed bundles
- Mix and match, with a custom box tier shown on its listing image
- Frequently bought together, shown on its listing image
- A sticky add to cart bar
- Tier badges, labels and a sold-out state
- Revenue and average order value by offer type
- Upcart, Monster Cart, AMP Slider and Opus Cart
- GemPages, PageFly and Releasit COD
I didn't find any AI features in it, apart from AI translations listed on its website.
Pricing: Pumper Bundles charges by the revenue its offers bring in:
- Free: up to $300 of added revenue
- Starter: $9.99/month, up to $1,000
- Growth: $29.99/month, up to $5,000
- Unlimited: $49.99/month, unlimited
- Trial: 7 days
Reviews: Pumper Bundles has 4.9 stars from 3,632 reviews on the Shopify App Store. A November 2026 reviewer who'd only just installed it says setup was easy and the guide was good. Another reviewer says the price block added extra H1 tags to product pages and that support only offered a JavaScript workaround.
Best for: A store selling one main product that wants a gift or BOGO reward at each quantity level.
I wouldn't choose it if: A bundle has to exist as its own product with a URL and SKU. Simple Bundles creates a real product for each one.
See Pumper Bundles on the Shopify App Store
7. Unlimited Bundles & Discounts: Best for offers that change by customer history

Unlimited Bundles & Discounts is a bundle app from Revy with automatic discounts on Shopify Functions. I'd choose it when you like build-your-own bundles but want a much lower ceiling on your bill.
Why I like this app:
My favourite detail is the build-your-own-bundle page, because I could fill it from single products or whole collections. Offers can also change with a customer's past orders, spend or tags, so a first-time buyer and a regular needn't see the same deal. Shoppers don't have to enter a code, since discounts apply automatically. Reviewers this year credit its live chat with quick bug fixes.
Compared with Fast Bundle:
Unlimited Bundles keeps build-your-own pages and tops out at $49.99/month on its listing, against $299/month on Fast Bundle. It leaves out AI tools, A/B testing and upsell widgets, which Revy sells as a separate app. One reviewer also found that shoppers had to go through a bundle builder instead of adding to cart directly.
Features:
- Build-your-own-bundle pages from products or collections
- Mix and match, fixed bundles and quantity breaks
- Automatic discounts on Shopify Functions
- Buy X Get Y, free gift and free shipping offers
- Customer targeting by orders, spend and tags
- Shopify Markets, multi-currency and multi-language
- Shopify POS and EComposer
- Automatic Bundle Match on paid plans
I didn't find any AI features in it.
Pricing: Unlimited Bundles charges by monthly bundle sales:
- Free: up to $100 of bundle sales
- Starter: $9.99/month, up to $1,000
- Growth: $29.99/month, up to $10,000
- Unlimited: $49.99/month, unlimited
- Trial: none listed
The Revy website shows tiers up to $99.99/month, so confirm your price in the app.
Reviews: Unlimited Bundles & Discounts has 4.8 stars from 727 reviews on the Shopify App Store. A reviewer of 6 years says it keeps improving. Another reviewer couldn't get an add-bundle-to-cart link for marketing emails.
Best for: A store that wants a different offer for repeat buyers, big spenders or tagged groups.
I wouldn't choose it if: Your email campaigns link straight to a bundle. Fast Bundle's Bundle as a Product gives each bundle its own URL, so I'd stay put.
See Unlimited Bundles & Discounts on the Shopify App Store
8. Bundler: Best for the same monthly cost at any sales level

Bundler is a bundle and quantity break app with a flat price on every paid plan. It suits a store that's had enough of watching a sales band before each promotion.
Why I like this app:
Bundler's pricing is what I kept coming back to, because a good month on bundles wouldn't change what I paid. I also found 3 styles of mix and match on Premium, including sectioned boxes. It works from the products I already had, so I'd have no duplicate listings to clear up later. The newest written reviews call it easy to use.
Compared with Fast Bundle:
Bundler costs $9.99/month or $19.99/month at any revenue, against $139/month on Fast Bundle at $10,000 of bundle sales. What you lose is A/B testing, AI tools and 24/7 chat, because one reviewer says support is AI and email only. Mix and match costs at least $9.99/month, and the analytics graphs need the $19.99/month plan.
Features:
- Quantity breaks and volume discounts
- Buy X Get Y
- Automatic discounts
- Shopify POS on the free plan
- Classic bundles
- Mix and match, tiered and sectioned, on Premium
- Landing pages, free shipping and funnel upsells on Premium
- Revenue, order value and most popular bundles on Executive
- Customer tag restrictions and scheduled dates
- PageFly, Seal Subscriptions and CartBot
I didn't find any AI features in it.
Pricing: Bundler charges a flat fee:
- Free: unlimited revenue and orders
- Premium: $9.99/month
- Executive: $19.99/month
- Trial: 7 days on paid plans
A July 2026 developer reply puts Premium at $8.99/month, so confirm the figure in the app.
Reviews: Bundler has 4.9 stars from 2,779 reviews on the Shopify App Store. One November 2026 reviewer on the free plan says they're impressed. In April 2026, another reviewer hit an upgrade banner on each bundle type they tried on the free plan.
Best for: A store that wants its bundle bill to stay put whether sales are $500 or $50,000.
I wouldn't choose it if: Your products have dozens of variants, because one reviewer says volume discounts displayed incorrectly on a product with 80. Simple Bundles offers Infinite Options for large variant counts.
See Bundler on the Shopify App Store
How do you choose between Fast Bundle and these alternatives?
Decide what's pushing you away from Fast Bundle first, then make sure the replacement fixes that at a price you can accept. These 5 checks will shorten the list.
Begin with the reason you're leaving. When reliability is the worry, rebuild your biggest sale offer during the trial and place a test order with a discount code alongside it. When the bill is the worry, take your monthly bundle sales and find the band each finalist would put you in.
After that, list the Fast Bundle features your store depends on. The Bundle Builder has close matches on AOV.ai Bundles, Simple Bundles and Unlimited Bundles, but A/B testing only comes with Kaching here, and I didn't find an AI bundle image generator on any alternative. Check which offers earned money last quarter before you count a feature as a loss.
Your theme needs a look too. I needed no code to match my test theme on nearly all of them, and Vitals built the result for my store when I asked Claude or ChatGPT. One Fast Bundle reviewer needed a Liquid workaround that only worked half the time, so check every finalist on your own theme and on your phone.
The rest of your store comes next. Fast Bundle names Appstle, Seal, Subi, Loop and Recurpay subscriptions, along with UpCart, AMP's slide cart, PageFly and GemPages. Simple Bundles names Recharge, Seal, Appstle and Loop, Bundler names Seal and Pumper names UpCart and AMP. Start with your subscription app, because I'd change a bundle app long before I moved subscribers.
Support is the final check, because Fast Bundle's 24/7 chat is a large part of what you'd be replacing. Pumper, Kaching and AOV.ai reviewers also praise fast chat, while one Bundler reviewer found only AI and email. A few customer success teams sorted my setup problems within minutes, and others needed hours to reply.
Choose Vitals if you also want to drop other app bills. Choose Bundler when a predictable fee matters most, Simple Bundles when a 3PL packs your orders and Kaching when A/B tests guide your offers. Stay on Fast Bundle when shoppers build their own boxes and your bundle sales stay under $3,000 a month.
Will a Fast Bundle alternative cost you less?
Nearly all of them will, especially once monthly bundle sales pass $3,000 and Fast Bundle moves to $139/month. The exceptions come at low bundle sales, where Vitals' $29.99/month and the order-based prices of Simple Bundles and Frequently Bought Together can be more than Fast Bundle's $19/month first band.
Fast Bundle charges by bundle sales, and so does Unlimited Bundles. Kaching and Pumper count the added revenue their offers bring in, Frequently Bought Together counts store orders and Simple Bundles follows your Shopify plan and order count. Bundler ignores all of that, but its free plan leaves out mix and match, and analytics cost $19.99/month. None of the cheaper apps has an AI image generator.
Say your bundles bring in $4,000 a month, and count that as added revenue on the apps that use it. Fast Bundle's $3,000 band is too small, so you'd pay $139/month on Standard (10K).These alternatives cost:
- AOV.ai Bundles: free on its listed plan, subject to its unpublished revenue limit
- Bundler: free, or $9.99/month with mix and match
- Kaching Bundles: $29.99/month
- Pumper Bundles: $29.99/month
- Unlimited Bundles: $29.99/month
Frequently Bought Together costs $24.99/month up to 500 orders, and Simple Bundles costs $24/month on Shopify Basic and $39/month on Grow or Advanced. Vitals isn't part of this sum, and it has one plan at $29.99/month with all 40+ apps.
Over 2 years at that level, Fast Bundle costs $3,336 on monthly billing and $2,760 on annual billing. Bundler's Premium plan comes to about $240 across the same 24 months, and its free plan costs nothing.
Check your last 3 months of bundle sales before you compare prices, then ask each finalist's support team whether a discounted order counts at its full price or its sale price.
What happens to your bundle products when you leave Fast Bundle?
They stay in your Shopify catalogue after you uninstall, so you'll need to delete them yourself. This only applies to bundles you created with Bundle as a Product.
Those bundles are real Shopify products with their own URLs, SKUs and collection placement. Once the app has gone, the listings can keep selling without any real stock behind them. So work through them before you remove the app, and unpublish each one first.
The alternatives split on this. Simple Bundles also creates a real product for each bundle, with stock taken from its components, and AOV.ai Bundles gives fixed bundles their own product pages. Bundler, Pumper and Vitals only discount the products you already have, so a later move wouldn't leave bundle products behind.
Before you delete a bundle product, write down its URL and add a redirect in Shopify, so ads and old emails still reach a working page.
Which alternatives can replace Fast Bundle's build-a-box builder?
AOV.ai Bundles, Simple Bundles and Unlimited Bundles come closest, because each one gives shoppers a page or builder for choosing the contents. Bundler and Pumper offer mix and match, but I didn't find a full builder on either.
Bundle Builder pages come on AOV.ai Bundles' listed free plan. Simple Bundles includes build-your-own boxes on its free plan as well, and Unlimited Bundles offers build-your-own pages from products or collections on every plan. Bundler's sectioned mix and match needs Premium, Pumper's listing image shows a custom box tier, and a Vitals mix-and-match bundle holds up to 5 products.
Build your largest box on your 2 finalists, then check how the discount reads at checkout.
When does it make sense to stay on Fast Bundle?
I'd stay on Fast Bundle if shoppers build their own boxes, your bundle sales stay under $3,000 a month and its chat team looks after your offers. It's a broad app, and few of these alternatives match all of it.
Its 5.0 rating from 3,639 reviews is the second largest review base here, and recent reviewers keep naming the agents who helped them. It has one of the widest bundle ranges in this comparison, from the Bundle Builder to add-ons and Bundle as a Product. Every paid plan also includes unlimited AI frequently bought together and the AI Bundle Image Generator.
Fast Bundle costs $19/month up to $1,000 of bundle sales and $49/month up to $3,000, with a 7-day trial. Its free plan only applies to development stores. See Fast Bundle on the Shopify App Store.
Before you leave, count how many orders came through the Bundle Builder or a bundle product, because those are the features you'd find hardest to replace.
How do you move from Fast Bundle to another app?
None of these apps lists an import from Fast Bundle, so you'll set up each bundle and builder again by hand. Your catalogue and past orders remain in Shopify, along with any bundle products the app created.
I'd save these from Fast Bundle before you change anything:
- Every bundle, builder, add-on and volume offer, with its discount and products
- Each Bundle as a Product listing, with its URL, SKU and collections
- Any subscription selling plans attached to your bundles
- Your analytics and A/B test results, as screenshots
Use these steps with any of the apps:
- Export your bundle products from Shopify and write down each offer in Fast Bundle.
- Install the new app on its free plan or trial, and set it up on a copy of your theme.
- Rebuild your offers, then check a few bundles and variants by hand.
- Set up the same bundle you have on Fast Bundle, so you're comparing like with like, then check it on your phone.
- Upgrade only if it does the job, then publish the theme.
- Remove Fast Bundle, its bundle products and any code it left behind, before your next billing date.
Almost every app took me 2 to 5 minutes, so setup time shouldn't decide this. Merchants describe mixed starts after that. A Pumper reviewer in November 2026 says the guide made setup easy, while some AOV.ai reviewers needed both an app block and an embed, and Frequently Bought Together reviewers struggled with manual bundles.
Keep your offer notes for at least 60 days, and watch the first sale on the new app closely, because the discount problems on Fast Bundle showed up during sale launches.
What changes in unusual situations?
A very large sale, several markets, POS or a headless build can change your choice. Most stores won't meet these situations.
During seasonal peaks, check what each app does at a limit. Crossing $10,000 of bundle sales moves a Fast Bundle store from $139/month to $299/month. One Pumper reviewer lost a best-selling offer when the store passed its limit, and Unlimited Bundles' website says bundles keep working above a cap while the plan moves automatically. Bundler and Frequently Bought Together's top plan have no limit to cross.
With several markets, compare what each app offers for translation and prices. AOV.ai Bundles, Unlimited Bundles and Frequently Bought Together all name Shopify Markets, Simple Bundles sets bundle prices and stock locations by market and Vitals shows bundles only in the countries you choose. One Bundler reviewer found it doesn't work with Shopify's translation app, and another reports trouble with per-market prices.
Some features depend on the plan. Fast Bundle sells Auto Bundle Detection for an extra $49/month and keeps post-purchase order splitting for Enterprise. Its listing names Shopify POS, but its pricing page puts POS under Enterprise, so check this before you stay for it. Bundler includes POS on its free plan, Unlimited Bundles names it too and Simple Bundles offers one location on Basic.
A headless store narrows the list. I didn't find Hydrogen documentation for Fast Bundle. Kaching works with Hydrogen, Simple Bundles supports it on Plus and AOV.ai Bundles documents a read-only Store API. Without a Hydrogen route on your finalist, plan on a custom build before you commit.
Which Fast Bundle alternative would I start with?
I'd start with Vitals, because it offers product bundles and 40+ other apps under one subscription, so more than one bill can go. Choose Simple Bundles when a warehouse needs every item on the order, and Bundler when you only want a flat fee. Stay on Fast Bundle when shoppers use the Bundle Builder and your bundle sales stay low. Install your 2 finalists, set up the same bundle on a copy of your theme, then compare what shoppers see and how many changes you had to make.

What do merchants often ask about Fast Bundle alternatives?
Which Fast Bundle alternative is best for gift boxes?
Simple Bundles is the best fit when someone packs the boxes for you, because each order lists every component SKU. AOV.ai Bundles makes more sense when you want Bundle Builder pages with no listed fee.
Is there a free alternative to Fast Bundle?
Yes, and Bundler is the clearest one, because its free plan has no revenue or order limit. AOV.ai Bundles lists only a free plan, though its docs mention a limit they don't state. Pumper is free up to $300 of added revenue, Unlimited Bundles up to $100 of bundle sales, Simple Bundles up to 3 bundles and 50 monthly orders and Frequently Bought Together up to 3 manual bundles. Simple Bundles' limit is monthly, so check whether Pumper's and Unlimited Bundles' limits reset too.
How much does Fast Bundle cost in 2026?
Fast Bundle costs $19/month up to $1,000 of monthly bundle sales, with a 7-day trial. It then costs $49/month up to $3,000, $139/month up to $10,000 and $299/month on Enterprise with no limit. Auto Bundle Detection adds $49/month, and annual billing runs from $180 to $1,380 a year.
Is Fast Bundle a good app?
Yes, Fast Bundle is a good app for build-a-box offers and complex discounts, with 5.0 stars from 3,639 reviews and 24/7 chat. An alternative makes more sense when bundle sales pass $3,000 a month or when discounts have failed you during a sale.
Can you move your bundles from Fast Bundle to another app?
No, I didn't find an import from Fast Bundle on these apps, so you'll set up each bundle again. Any Bundle as a Product listings stay in Shopify until you delete them.
Do Fast Bundle alternatives slow down a store?
A single bundle app didn't slow my test store, but many stores have 10 to 15 apps and every extra one adds to the load. Vitals surprised me, because its 40+ apps load from one script, so I could switch any of them on or off without worrying about load time. One Fast Bundle reviewer reports about 3 seconds of delay on add to cart, so time yours before and after you move.
