7 Best Fast Bundle Alternatives for Shopify [2026]

Looking for a Fast Bundle Alternative?

Fast Bundle, listed as FBP Fast Bundle & Upsell App and formerly FBP Fast Bundle Product, is a popular Shopify app for building bundles, mix-and-match deals and volume discounts. It does that job well, but it might not be the right choice for most Shopify store owners.

So, we compared seven alternatives on the bundles they can create, where their offers can appear between the product page and the thank-you page, and how many other apps each one can replace. Vitals is our app, so we've noted its gaps too.

What Is Fast Bundle Shopify App?

FBP Fast Bundle & Upsell App is a Shopify app for selling products together and adding upsells around them. Its widget shows bundles, volume tiers and add-ons on the product page, and the same offers can show in a cart drawer or a pop-up.

Here's what you can do with Fast Bundle:

• Product bundles: Create fixed bundles, multipacks, mix-and-match bundles and a Bundle Builder page where shoppers can build their own box.
• Bundles as products: Turn a bundle into a real Shopify product with its own SKU, so 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, with ready-made templates.
• AI help: Get AI frequently bought together suggestions, AI bundle images and AI-written titles and descriptions for bundle products.
• Sales across channels: Sell subscription bundles through Appstle, Seal and Loop, and connect with UpCart, AMP slide carts and page builders such as PageFly and GemPages.

Where Fast Bundle stands out is its range of bundle types. Few apps cover bundle-as-product listings, a Bundle Builder page and AI pairings in one place, which suits stores with large catalogs and many ways to sell a set.

Customer reviews most often praise its 24/7 chat team, which frequently builds a merchant's first bundles for them.

How Much Does 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

Fast Bundle holds a 5.0 rating from 3,545 reviews but doesn't carry the Built for Shopify badge. Still, merchants who switch away from it mention these reasons:

• Shopify removed the app from the App Store between July 17 and August 3, 2026, after a security incident, and some reviews describe bundles breaking during that time
• The price follows bundle revenue, so the plan climbs as bundles sell, and one review describes a bill that reached $299 a month
• Offers stop at the product page, the cart drawer and pop-ups, with no checkout or thank-you page offers listed
• Shopify POS integration and automatic bundle detection in the cart sit on the Enterprise plan
• Bundle-as-product listings stay in Shopify after uninstalling and have to be deleted by hand

Switching makes the most sense for stores that want bundles, after-checkout offers and their other storefront apps on one predictable subscription.

4. Unlimited Bundles & Discounts

Best for: Stores that show bundles only to customers with a set order count, spend or tag

Rating: 4.8 (727 reviews) | App type: Standalone | Free trial: No | Built for Shopify: Yes

Unlimited Bundles & Discounts, made by Revy Apps, applies its bundle discounts automatically through Shopify Functions. Offers can target customers by how many orders they've placed, how much they've spent or their tags. It suits stores that reward repeat buyers with different bundles from first-time visitors.

5. Zoorix: Bundles & Cross Sell

Rating: 4.8 (804 reviews) | App type: Standalone | Free trial: No | Built for Shopify: Yes

Simple Bundles & Kits, from Freshly Commerce, is the closest match here to Fast Bundle's bundle-as-product option.

Rating: 4.9 (379 reviews) | App type: All-in-one | Free trial: 14 days | Built for Shopify: Yes

FoxKit: Upsell & Bundles App comes from FoxEcom, the maker of the Minimog theme, and positions itself as an all-in-one sales boost app. Bundles and quantity breaks sit next to cart and post-purchase upsells, pop-ups, pre-orders and a mega menu. It suits stores already on a FoxEcom theme.

How Many Apps Each Option Replaces

Every app a store adds can load its own code on each page, which affects load time. This is how many separate apps each option covers, by our count.

How we counted it:

• Vitals - All in One App replaces up to 40+ single-purpose apps, starting with a bundle app, a quantity break app, a post-purchase offer app, a cart upsell app, a pop-up app and a product reviews app
• Bundler » Product Bundles App replaces a bundle app and, for stores that link to bundle pages, a landing page app
• Kaching Bundles App & Upsells replaces a quantity break app, with Kaching's cart and post-purchase apps installed separately
• Unlimited Bundles & Discounts replaces a bundle app and a free gift or BOGO app
• Zoorix: Bundles & Cross Sell replaces a bundle app, a cross-sell app and a basic cart drawer app
• Simple Bundles & Kits replaces a bundle app and the inventory sync a store would otherwise need for kits
• FoxKit: Upsell & Bundles App replaces 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 replaces a bundle app, a free gift app and a frequently bought together app

A store using Fast Bundle next to a post-purchase app, a reviews app and a pop-up app can move all of them to one Vitals subscription that covers 40+ apps.

When Should You Stay on Fast Bundle

Fast Bundle is still the better choice in two cases.

• Your fulfilment setup expects bundles to exist as Shopify products with their own SKU, and you also want mix-and-match and Bundle Builder pages in the same app
• You lean on its AI pairings and AI bundle images across a large catalog

Switch when you want offers after checkout and a bill that doesn't rise with every bundle sold.

How to Migrate From Fast Bundle

Fast Bundle's bundle-as-product listings are real Shopify products with their own URLs and SKUs, and they stay in the store after you uninstall. Plan the move so those pages don't keep selling without stock.

1. List every live offer with its products, tiers, discounts and add-ons, and note which bundles exist as their own products
2. Install Vitals - All in One App and rebuild each offer in the Vitals Product Bundles app or the Vitals Volume Discounts app, or describe it to the AI Offer Generator
3. Set up a Vitals post-purchase offer if you want an upsell after checkout
4. Test every offer on a duplicate theme and place a test order for each one
5. Redirect the URLs of Fast Bundle's bundle products to the matching product pages, then delete those products and remove the app's blocks from your theme
6. Publish the theme and uninstall Fast Bundle

Shopify stores such as Strapsology moved their single-purpose apps to one Vitals subscription.

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. It's our app, so check its entry for what it doesn't do.

2. Why do merchants switch from Fast Bundle?

Its price follows bundle revenue, so the plan rises as bundles sell. It lists no checkout or post-purchase offers, it isn't Built for Shopify, and Shopify removed it from the App Store for over two weeks in July and August 2026, and some reviews say their bundles broke during that time.

3. How do Vitals and Fast Bundle compare on bundle features?

Both offer fixed and mix-and-match bundles, quantity breaks, Buy X Get Y, free gifts and add-ons, and both have AI help. Fast Bundle adds bundle-as-product listings and a Bundle Builder page. Vitals adds bundle placements on the thank-you page, one-click post-purchase offers and its other storefront apps in the same subscription.

4. Can Vitals replace Fast Bundle and other apps at the same time?

Yes. Vitals can replace Fast Bundle along with separate apps for post-purchase offers, pop-ups, free gifts and product reviews.

5. How do these Fast Bundle alternatives affect store speed?

Each app a store installs can add its own scripts to the storefront, so speed depends on how many apps are installed as well as which ones. Vitals - All in One App loads its bundles, post-purchase offers and other apps from one script. A store that covers the same jobs with several single-purpose apps loads a script for each. 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 has the AI Offer Generator and Vitals MCP, which lets Claude or ChatGPT draft and edit offers for you to review. Simple Bundles & Kits has Bundle Magic AI, Zoorix: Bundles & Cross Sell has AI cross-sell suggestions, and Kaching Bundles App & Upsells lists AI recommendations. None of those three list 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 has one-click post-purchase offers and thank-you page bundles, and FoxKit: Upsell & Bundles App lists post-purchase offers. Kaching sells post-purchase offers as a separate app, and Bundler, Unlimited Bundles, Zoorix and Simple Bundles don't list them.

8. How do I migrate from Fast Bundle to Vitals?

List your live offers and the bundles that exist as their own products, then rebuild them in Vitals Product Bundles or Volume Discounts, or with the AI Offer Generator. Test on a duplicate theme, redirect and delete Fast Bundle's bundle products, remove its theme blocks and uninstall.
