The best Fast Bundle alternatives

The best Fast Bundle alternatives are BundleUp, Kaching Bundles, Bundler, Simple Bundles and Shopify Bundles. Fast Bundle covers many bundle types in one app, so the right switch depends on which part of it you actually use.

We make BundleUp, one of the alternatives below. We've tried to be fair; here is when another app is the better pick. Facts about other apps come from their Shopify App Store listings, checked on 24 October 2026.

What Fast Bundle is good at

  • Many offer types: free gift, BOGO, buy X get Y, upsells and bundles.
  • A bundle builder for mix-and-match bundles, fixed bundles and custom kits.
  • Frequently bought together, add-ons and cross-sells.
  • Volume discounts and quantity breaks.
  • Bundle offers for Shopify POS as well as product pages.
  • Rated 5.0 from 3,586 reviews when we checked.

Why some stores look elsewhere

You use one kind of offer

If you mainly sell quantity breaks on a product page, an app focused on that can be simpler to set up and run.

How the price grows

Paid plans are set by monthly bundle sales: $19 a month up to $1,000 and $49 up to $3,000, per its listing. Automatic bundle detection is an optional extra at $49 a month.

A free plan for a live store

Fast Bundle's free plan is for development stores. Bundler, Simple Bundles and Shopify Bundles have free options for live stores.

BundleUp Our app

By Rofsky Solutions (Spikecom Group FZCO)5.0 from 72 reviewsOn the App Store since 2024

Best for: Quantity breaks, bundles and free gifts on a product page, built by AI from a sentence or a screenshot.

What stands out

  • Describe the offer, or paste a screenshot of a design you like, and Design Studio builds it with your real products
  • Tiers with a percentage, a fixed amount per unit or a fixed price per offer

  • It can't copy a product's subscription options into a bundle, so it is not the pick for subscribe-and-save bundles.
  • No revenue reports inside the app. Use Shopify's reports for orders with the BundleUp discount.
  • No free plan. A usage fee is added as store revenue grows, with a monthly cap.

Price. One plan with every feature: $13.99 per 30 days after a 7-day free trial, plus a usage fee based on the store's revenue in the cycle, with a monthly cap. Current prices are on the Shopify App Store listing.
