If you are searching for Selleasy alternatives, you probably want one of three things: offers in more places than one, fewer separate subscriptions, or a way to measure which offer actually earns money. Selleasy is an upsell and cross-sell app for Shopify, 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 options below. We do not publish figures about Selleasy, because we cannot verify them: check its listing for current features and pricing. Every figure about the other competitors comes from the public Shopify App Store listings as read on August 31, 2026, and we say where each of them is the better choice. Prices and limits change, so confirm them before you decide.
How to Choose a Selleasy Alternative
“Best upsell app” is a poorly framed question. An offer on a product page, a cart drawer upsell and a post-purchase one-click offer all raise revenue, but they act on different moments of the buying decision. Choose the surface you want to improve first, then pick the app that handles it best.
- Product page: bundles, quantity breaks and volume discounts that raise units per order before the cart.
- Cart and cart drawer: cross-sells, free shipping progress bars and gifts shown right before checkout.
- Post-purchase: one-click offers shown after payment, once the shopper has already committed. Our guide to Shopify one-click upsell covers how they work.
Then use the same checklist for every candidate: which offer types it supports, where it can show them, whether recommendations are manual or rule-based, whether it works with your theme and your other apps, and whether you can see the revenue each offer brings and A/B test it. Overlap is the hidden cost: two apps that both inject offers into the cart can conflict. Ideally each surface has one owner.
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. Selleasy is not in the table: check its listing for its current modules.

How Each Alternative Differs
Moon Bundles
Moon Bundles is a Shopify app with four modules on every paid plan: bundles, volume discounts, free gifts that unlock as the cart grows, and a cart drawer with a one-click post-purchase upsell, plus A/B testing across them. It holds a 5.0 rating across 613 public reviews (as of August 31, 2026). Paid plans run from $19.99 to $79.99 a month, each with a 7 day free trial, and a free plan covers up to $500 of generated revenue (see pricing).
It is also AI-powered in concrete ways: an AI assistant and an MCP connector come with every plan, so you can manage your offers from Claude, ChatGPT or Gemini. Moon Bundles Agents watch your results and prepare the next tests for you to approve, and Claude Cowork lets you schedule recurring checks. Where it falls short: it has fewer public reviews than Kaching Bundles, and it is not the deepest tool for a pure cart drawer or a pure post-purchase funnel.
Kaching Bundles
Kaching Bundles has the largest body of public reviews in this category: 5,416 at 5.0 stars (as of August 31, 2026), and a bundle editor with a long track record. Its cart drawer and post-purchase upsell are separate apps, billed separately. Its Starter plan is $14.99 a month, below our first paid plan. Details are in Moon Bundles vs Kaching Bundles.
Rapi Bundles
Rapi Bundles covers bundles, volume discounts, post-purchase upsells and A/B testing in one app, with 1,426 reviews at 5.0 (as of August 31, 2026). Its uncapped Elite plan is $59 a month, cheaper than our $79.99 Premium. It does not cover a cart drawer or progressive gifts. See Moon Bundles vs Rapi Bundles.
Amose Bundle
Amose Bundle has the lowest uncapped plan in this comparison, $29.99 a month, and a broad scope on paper. The public track record is short: 26 reviews at 4.3 (as of August 31, 2026), and its listing does not mention A/B testing. See Moon Bundles vs Amose Bundle.
UpCart and AfterSell
UpCart and AfterSell, both published by Rokt, are the specialists. UpCart is a cart drawer with deep customization; AfterSell is a post-purchase funnel with downsells and checkout upsells on Shopify Plus. Neither has been listed on the Shopify App Store since October 2026, so treat the figures in our comparisons (read on August 31, 2026) as a dated snapshot, not as current ratings or prices. If the cart drawer or the post-purchase funnel is your whole strategy, they go deeper than we do. See Moon Bundles vs UpCart and Moon Bundles vs AfterSell.
Other upsell apps
Many other upsell, cross-sell and personalization apps exist on the Shopify App Store. We do not describe them in detail here, because we cannot verify their current features. For a wider view by offer type, read our guide to the best Shopify upsell apps.
Which Alternative Fits Your Store?
- You want bundles, a cart drawer and a post-purchase upsell in one app: Moon Bundles is the only option in this list that includes all of them plus gifts and A/B testing on every paid plan.
- Reviews decide for you: Kaching Bundles, with by far the largest review base.
- Price decides for you: Amose Bundle or Rapi Bundles, both cheaper at the top of the range. Weigh Amose’s short track record.
- The cart is your only lever: UpCart.
- Post-purchase is your whole strategy: AfterSell.
- Your Selleasy offers already work: stay. Switching only makes sense if a gap, such as a missing placement or no measurement, costs you revenue.
What to Check Before Switching
- Baseline: record conversion rate, average order value and units per order for a few weeks. If you need a refresher, read Shopify average order value.
- Map what you use: list the offers and placements you rely on today and confirm the new app supports them.
- Test one surface: install on a duplicate theme or run a controlled split, changing one variable at a time.
- Judge on revenue per visitor: a higher average order value that lowers conversion is not a win.
- Clean up: confirm that removing the old app leaves no widget or code behind.
Frequently asked questions
Can a Shopify store use more than one upsell app?
Yes, but it works best when each app has a distinct role, such as one for product bundles and another for the cart. Overlapping widgets can create duplicate offers and make results harder to read. Before adding an app, check how its placement and rules interact with the tools already installed.
Are product bundles a substitute for upsells?
Not always. A bundle groups related products into one offer, while an upsell encourages a shopper to upgrade or add an item at a given moment. Bundles can be one part of an upsell strategy, but they do not cover a cart offer or a post-purchase recommendation on their own.
How can I tell whether a Selleasy alternative is improving performance?
Compare before and after with metrics tied to your goal: average order value, conversion rate and revenue per visitor. Account for discounts and traffic changes so you do not credit the app for unrelated shifts, and test one change at a time over comparable periods.
Will an alternative work with my Shopify theme?
It depends on the app, the theme and where you want offers to appear. Test the storefront behavior on your theme, including mobile and the cart, before relying on it, and ask the vendor about anything the documentation does not cover.
What should I check before switching from Selleasy?
Map the offers and placements you rely on, confirm the replacement supports them, and check whether settings and offers must be recreated. Test with representative products and devices before removing the old placements, then compare performance with the same metrics.
