7 Best Fast Bundle App Alternatives in 2026
Looking for a Fast Bundle Alternative?
Fast Bundle is a popular Shopify app for fixed bundles, mix-and-match deals, volume discounts and AI bundle suggestions.
However, some merchants report problems with broken bundles and a bill that keeps climbing. Reviews describe bundles breaking while Shopify had the app off the App Store in July and August 2026. The plan also rises as bundle revenue grows.
To help you find the right alternative, we've compared the seven best Fast Bundle app alternatives based on app type, features, customization, pricing, AI capabilities, and the number of additional apps included in the same subscription.
Since Vitals is our app and one of the alternatives, we've also highlighted its limitations.
What Is the Fast Bundle App?
FBP Fast Bundle & Upsell App, formerly FBP Fast Bundle Product, is a Shopify app for product bundles, discount offers and add-ons. It lets merchants build bundles, set volume and BOGO deals, and show the same offers in a cart drawer or a pop-up.
Here's what you can do with the Fast Bundle app:
- Product bundles: Create fixed bundles, multipacks and mix-and-match bundles in a widget on the product page. A Bundle Builder page lets shoppers build their own box.
- Bundles as products: Turn a bundle into a Shopify product with its own SKU. Its stock stays in step with the items inside it.
- Discount offers: Set volume discounts, quantity breaks, BOGO, Buy X Get Y and free gift offers. Ready-made templates give you a starting point.
- AI help: Get AI frequently bought together suggestions and AI bundle images. AI can also write titles and descriptions for bundle products.
- Sales across channels: Sell subscription bundles through Appstle, Seal and Loop. It also connects with UpCart, AMP slide carts, PageFly and GemPages.
How Much Does the Fast Bundle App Cost?
Prices from fastbundle.co on October 14, 2026, with a 7-day free trial. Stores above $10,000 in monthly bundle revenue move to a custom Enterprise plan.
Why Shopify Merchants Look for Fast Bundle Alternatives
The Fast Bundle app holds a 5.0 rating from 3,545 reviews and doesn't carry the Built for Shopify badge. Still, some merchants switch to another app for these reasons:
- Time off the App Store: Shopify removed the app from the App Store between July 17 and August 3, 2026, after a security incident. Some reviews describe bundles breaking during that time.
- Revenue-based pricing: The plan climbs as bundle revenue grows. One review describes a bill that reached $299 a month on Enterprise.
- No offers after checkout: Offers show on the product page, in the cart drawer and in pop-ups. The listing names no checkout or thank-you page offers.
- Enterprise-only extras: Shopify POS integration needs the Enterprise plan. So does automatic bundle detection in the cart.
If any of these sound familiar, an all-in-one app alternative may suit your store better.

Its range is the draw, with cart and post-purchase upsells next to bundles and quantity breaks. That means one install handles offers both before and after checkout.

How Many Apps Each Option Replaces
Every app you install can add its own code to your storefront, and that code affects load time. The table below shows how many separate apps each option replaces, based on our count.
Here's what each option replaces:
- Vitals - All in One App: 40+ apps, including a bundle app, a quantity break app, a BOGO app, a post-purchase offer app, a cart drawer app and a free shipping bar app
- Bundler » Product Bundles App: a bundle app and, for stores that link to bundle pages, a landing page app
- Kaching Bundles App & Upsells: a quantity break app and a split-testing app
- Unlimited Bundles & Discounts: a bundle app, a BOGO app and a free gift app
- Zoorix: Bundles & Cross Sell: a bundle app, a cross-sell app and a basic cart drawer app
- Simple Bundles & Kits: a bundle app and the inventory sync a store would otherwise need for kits
- FoxKit: Upsell & Bundles App: a bundle app, a cart and post-purchase upsell app, a pop-up app, a pre-order app, a size chart app and a mega menu app
- FBP Fast Bundle & Upsell App: a bundle app, a frequently bought together app and a free gift app
Say you use the Fast Bundle app with a post-purchase app, a free shipping bar app and a reviews app. That's four apps loading four scripts. With Vitals, you can replace all four apps with one subscription.
When Should You Stay on Fast Bundle?
The Fast Bundle app is still the better choice if:
- Your fulfilment setup needs each bundle to exist as a Shopify product with its own SKU
- You want mix-and-match bundles and a Bundle Builder page from the same app
- You rely on its AI pairings and AI bundle images across a large catalog
On the other hand, switch to Vitals if you want a one-click offer after checkout next to your bundles, on plans priced by orders rather than bundle revenue. You also get a slide-out cart drawer and a free shipping bar under the same plan.
How to Migrate From Fast Bundle
The Fast Bundle app's bundle-as-product listings are real Shopify products with their own URLs and SKUs. They stay in your store after you uninstall, so plan the move to keep those pages from selling without stock.
- List every live offer with its products, tiers, discounts and add-ons. Mark which bundles exist as their own products
- Install Vitals - All in One App, then duplicate your live theme to work on. Rebuild bundles in Vitals Product Bundles App, quantity breaks in Vitals Volume Discounts App and Buy X Get Y deals in Vitals BOGO App. Or type a one-line description and let the AI Offer Generator build the offer
- Add a one-click offer after checkout in Vitals Upsell Builder App if you want an upsell once the order is placed
- Place a test order for every offer, so shoppers never see a missing bundle
- Redirect each Fast Bundle bundle product's URL to the product page of the bundle's lead item, where the Vitals bundle now shows
- Update ads, Shopping feeds and email links that point to those bundle products. Then delete the products and remove the app's blocks from your theme
- Publish the theme, then uninstall the Fast Bundle app

Frequently Asked Questions
1. What is the best Fast Bundle alternative for Shopify?
Vitals - All in One App is the best Fast Bundle alternative for most stores. It's the only all-in-one app that includes 40+ apps, such as product bundles, quantity breaks, post-purchase offers and reviews, in one subscription. Since Vitals is our app, we've listed its limitations in its review above.
2. Why do merchants switch from Fast Bundle?
The Fast Bundle app focuses on bundles and discounts before checkout. If you want one-click post-purchase offers, you need to install another app. Lower-rated reviews also mention bundles that broke while Shopify had the app off the App Store in 2026, and a bill that reached $299 a month on Enterprise.
3. How do Vitals and Fast Bundle compare on bundle features?
Both offer fixed bundles, quantity breaks, Buy X Get Y deals and free gifts. Only the Fast Bundle app has bundle-as-product listings, a Bundle Builder page and AI bundle images. Vitals, on the other hand, includes thank-you page bundles, one-click post-purchase offers and an AI Offer Generator that builds an offer from a sentence, plus the rest of its 40+ apps.
4. Can Vitals replace Fast Bundle and other apps at the same time?
Yes, for most stores. Vitals can replace the Fast Bundle app's fixed bundles, quantity breaks, BOGO deals and free gift offers. It can also replace separate post-purchase offer, cart drawer and reviews apps. The one exception is bundles sold as their own products with a SKU, which Vitals doesn't offer.
5. How do these Fast Bundle alternatives affect store speed?
Each app you install can add its own scripts to your storefront. That means speed depends on how many apps you have, not just which ones. Vitals - All in One App loads its bundles, post-purchase offers and other apps from one script. If you use several single-purpose apps instead, each one loads its own script. We didn't speed-test these apps, so check your own pages before and after a change.
6. Which Fast Bundle alternatives have AI features or MCP support?
Not all of them. Vitals' AI Offer Generator turns a sentence you type into an offer. Vitals MCP lets Claude or ChatGPT draft and edit offers, which you review before they go live. Simple Bundles & Kits has Bundle Magic AI. Zoorix: Bundles & Cross Sell has AI cross-sell suggestions. Neither lists MCP support. Bundler, Unlimited Bundles and FoxKit list no AI features.
7. Which Fast Bundle alternatives show offers after checkout?
Not all of them. Vitals - All in One App shows thank-you page bundles and one-click offers after checkout. FoxKit: Upsell & Bundles App lists post-purchase offers too. Kaching offers them only through a separate app. Bundler, Unlimited Bundles, Zoorix and Simple Bundles don't list them, and neither does the Fast Bundle app.
8. How do I migrate from Fast Bundle to Vitals?
List your live offers first, and mark the bundles that exist as their own products. Then, on a duplicate theme, rebuild bundles in Vitals Product Bundles App, tiers in Vitals Volume Discounts App and Buy X Get Y deals in Vitals BOGO App. Place a test order for each one. Next, redirect each bundle product to its lead item, update ads and feeds, and delete those products. Uninstall the Fast Bundle app last.
