Rapi Bundles Alternatives: 5 Shopify Apps Compared
If you are searching for Rapi Bundles alternatives, you probably want one of three things: more offer types, more placements than the product page, or fewer apps to maintain. Rapi Bundles is a solid app, so the useful question is not “which app is better?” but “which gap am I trying to close?”
A note on transparency: Moon Bundles is our app, and it is one of the five options below. Competitor details come from the public Shopify App Store listings as read on August 31, 2026, and we say where each competitor is the better choice. Prices and limits change, so confirm them on each listing before you decide.
Why Look for a Rapi Bundles Alternative?
On the modules we compare, Rapi Bundles covers product bundles, volume discounts and quantity breaks, a one-click post-purchase upsell and A/B testing. It also offers API and MCP access on its top plan and covers subscription bundles. Its uncapped plan is cheaper than our top plan, and that gap is real if you already generate a lot of revenue through bundles.
The gaps are on the other side of the table. Rapi does not cover a cart drawer or free gifts unlocked by cart value. Those are the usual reasons to look at an alternative:
- You want a cart drawer where shoppers see offers right before checkout.
- You want progressive gifts that unlock as the cart value grows.
- You want to test before paying and need a free plan with room to see a real effect.
- You want fewer apps and fewer scripts on the storefront.

The Alternatives at a Glance
Coverage below follows our comparison pages, as of August 31, 2026. “Separate app” means the module exists but is sold as another app with its own plan.
| App | Best known for | Cart drawer | Post-purchase upsell | A/B testing |
|---|---|---|---|---|
| Moon Bundles | Four modules in one install: bundles, volume discounts, free gifts, cart drawer | Included | Included | Included |
| Kaching Bundles | Bundles, with the largest review base in the category | Separate app | Separate app | Included |
| Amose Bundle | Wide scope at a low price | Included | Included | Not covered |
| UpCart | Cart drawer specialist | Included | Not covered | Not covered |
| AfterSell | Post-purchase specialist | Not covered | Included | Included |
UpCart and AfterSell are both published by Rokt, and neither is listed on the Shopify App Store since October 2026. Check their current availability with the publisher before planning a switch. The figures in our comparison pages for these two are dated and should not be read as current.
How Each Alternative Differs
Moon Bundles
Moon Bundles combines bundles, volume discounts, free gifts and a cart drawer with upsells, plus a one-click post-purchase upsell, in a single install. The free Discovery plan runs up to $500 of generated revenue with one module of your choice. Paid plans cost $19.99, $39.99 and $79.99 a month, each includes all four modules, and A/B testing across modules arrives with the Pro plan.
It is AI-powered in two concrete ways: an MCP connector on every paid plan, which lets you work from Claude, ChatGPT or Gemini with nothing shipping until you approve it, and Agents that follow your offer results and prepare the next tests, which you can start from Claude Cowork.
Where it is weaker than Rapi: the top of the range costs more, and Rapi covers subscription bundles.
Kaching Bundles
Kaching has the largest body of public reviews in this category and a long-established bundle editor, with layouts, custom CSS and HTML, multi-currency and multi-language. If social proof decides for you, it is hard to beat. The catch is scope: the cart drawer and the post-purchase upsell are separate Kaching apps, each with its own plan, so matching what one Moon Bundles install does means several subscriptions. See Moon Bundles vs Kaching Bundles.
Amose Bundle
Amose lists bundles, quantity breaks, gifts, a cart drawer and post-purchase offers, and its unlimited plan is the cheapest in our comparison. It has far fewer public reviews than the others and its listing does not mention A/B testing, which means changing offers without measuring what they earn. See Moon Bundles vs Amose Bundle.
UpCart
UpCart is a cart drawer specialist, and the depth shows: announcements, sticky cart, countdown timers, rewards and tiered progress bars. If the cart is the only thing you want to change, a dedicated tool is a defensible choice. It does not cover bundles, so you would keep a bundle app next to it. See Moon Bundles vs UpCart.
AfterSell
AfterSell has the deepest post-purchase funnel we compare: upsells and downsells, a drag-and-drop editor, and checkout upsells on Shopify Plus. If post-purchase is your whole strategy, it goes deeper than Moon Bundles. It does not cover bundles, volume discounts, gifts or a cart drawer. See Moon Bundles vs AfterSell, and our guide to the Shopify post-purchase upsell.
Which Alternative Fits Your Store?
- You need a cart drawer or progressive gifts in the same app as your bundles: Moon Bundles, or Amose Bundle if price is the deciding factor.
- The cart is your only leak: UpCart, alongside a bundle app.
- Post-purchase is your main lever: AfterSell, especially on Shopify Plus.
- Reviews decide for you and you only need bundles: Kaching Bundles.
- You are already happy with bundles and volume discounts: stay on Rapi Bundles. Switching for a layer you do not need costs time and risks conversion.

What to Check Before Switching
- Inventory your live offers: every bundle, quantity break and tier, with products, prices and conditions.
- Record a baseline: conversion rate, average order value and revenue per visitor over a representative period.
- Check theme compatibility and discount stacking on a duplicate theme before touching the live one.
- Read the current plan details on the listing, since limits and prices change.
- Run both setups against each other, ideally with an A/B split, and switch only when the new offers match or beat the baseline.
- Remove leftover scripts and disable the old app once nothing duplicates on the storefront.
Frequently asked questions
Is Rapi Bundles a bad app?
No. Rapi Bundles covers bundles, volume discounts, post-purchase upsells and A/B testing, and it is cheaper than Moon Bundles at the top of the range. People look for alternatives for specific reasons: a missing cart drawer, no progressive gifts, a free plan that is too small to test with, or the wish to consolidate apps. If none of those apply, there is no reason to switch.
Which alternative covers the most modules in one app?
On the modules we compare (bundles, volume discounts, free gifts, cart drawer, post-purchase upsell and A/B testing), Moon Bundles covers all six in one install. Amose Bundle lists five of them on paper, without A/B testing. Kaching Bundles covers the cart drawer and the post-purchase upsell through separate apps. Check each listing before deciding.
Can I test Moon Bundles without paying?
Yes. The Discovery plan is free up to $500 of generated revenue and includes one module of your choice. Every paid plan starts with a 7 day free trial and includes all four modules and the MCP connector. See the pricing page for the plans.
What does AI-powered mean for Moon Bundles?
Two concrete things. Every paid plan includes an MCP connector, so you can drive the app from Claude, ChatGPT or Gemini, and nothing ships until you approve it. And Moon Bundles Agents watch your offer results with you and prepare the next tests. It does not mean guaranteed results.
Should I run Rapi Bundles and a new app at the same time?
Only during a controlled test. Two apps changing prices or discounts on the same products can stack or conflict. Test the new app on a duplicate theme or on a limited set of products, compare revenue per visitor against your baseline, then retire the old app once nothing duplicates on the storefront.
