• Comparing the two before you install → keep reading, this is for you
• Already on Rebuy and thinking about switching → the differences below still apply, but head to the Rebuy to Selleasy Migration Guide for the switch-over steps
Before comparing the two apps, here is what is actually at stake:
• These apps sit where the money is. The product page, the cart, and the checkout decide whether an order completes and how large it is.
• Both run on AI - the difference is control. Selleasy's AI is on every plan and can be told what to recommend. Rebuy runs on its own algorithm.
• They are scoped differently. Selleasy does upsells and cross-sells. Rebuy also does onsite search, smart collections, automated flows, and A/B testing, sold as separate packages you buy individually.
• They grow differently. Selleasy’s Pro plan is a flat $49/mo with unlimited orders. Rebuy prices every package by order volume, so its bill follows your growth.
Both apps can automatically recommend products or let you choose them manually. The key difference is how much control you have over those recommendations.
Rebuy uses separate data sources and relies heavily on store history for its recommendations. Its AI options cannot be prompt-engineered, and its recommendations become more useful as your order history grows.
Selleasy keeps product selection within the campaign setup and gives you more control. You can choose products manually, use metafields, or use Shopify AI and prompt-engineered Selleasy AI. Its product-based AI works without order history, making it useful even for newer stores or large catalogues.
In short, Rebuy puts more of the product-selection decision into its recommendation engine, while Selleasy gives merchants more control over defining what the AI should recommend.
Which plan or package unlocks what, rather than a full settings list.
Selleasy has a ★4.9 average rating across 2,480 reviews, installed on 46,115 Shopify stores. Rebuy has ★4.7 across 743 reviews on 15,095 stores (Store Leads, August 2026).
Two things need deciding before you rebuild anything. If Smart Cart is serving as your storefront cart drawer, you need a replacement in place first. And any Rebuy offer that blends its own recommendations with your manual picks has to be reconstructed rather than copied across. Our Rebuy to Selleasy Migration Guide covers the sequence, and tells you upfront whether the switch makes sense for your setup.
Because AI is included on every plan and you can tell it what to recommend. Selleasy AI and Shopify AI are available from the free tier, starting with 50 credits a month, and you can prompt-engineer their recommendations instead of relying solely on an algorithm.
All 17 upsell and cross-sell strategies are included on every plan, across every placement and format. Free setup assistance through chat and Zoom is also available on every plan.
Pricing stays predictable as you grow: $0 to $29 while you're small, then $49/month on Pro with unlimited orders and priority support. Selleasy also has the Built for Shopify badge, a higher rating across more than three times as many reviews as Rebuy, and runs on 46,000+ stores compared with Rebuy's 15,000+.
When you want on-site search, smart collections, automated flows, and real A/B testing in the same tool, Rebuy covers all of it.
The failure mode to avoid is buying that wider product with nobody to run it - paying package prices, plus $499/mo if you want priority support, for offers you could have configured yourself.
Selleasy and Rebuy differ in who controls the product recommendations. With Selleasy, you choose to offer products by hand, by collection, by tag, or by attribute - and you can prompt-engineer Selleasy AI to recommend specific types of products. Rebuy runs on its own recommendation algorithm: it personalises offers per shopper using it’s “Recently viewed” and “Buy it again” offer types,, but you cannot tell it what to recommend.
Yes, at comparable points. Selleasy costs $0 to $29/month by order volume, then a flat $49/month on Pro for unlimited orders with priority support included. Rebuy showed $98/month for all four packages on a test store, and sells priority support separately at $499/month. Rebuy publishes no ceiling, so its cost rises with your order count.
Rebuy does more for that money- on-site search, smart collections, flows, and A/B testing. Whether it's worth it depends on whether you'll use them.
No. Selleasy shows the same offer for the same trigger product, so you always know what a customer will see. What you control is the kind of products the AI puts forward - prompt-engineer Selleasy AI, and the recommendations follow your brief. Rebuy does vary offers per shopper through Recently Viewed and Buy It Again, but that runs on its own algorithm with no way for you to steer it.
Not on a live store. Rebuy is free only on development stores.
Its free option for live stores is Rebuy Monetize, which places other brands' ads on your thank you and order status pages and pays roughly $0.20 to $0.35 per order, for US and Canada shoppers only.
Selleasy's free tier runs your own offers with all 17 strategies unlocked, up to 50 orders a month, free forever.
Only on Shopify Plus. Offers on the checkout page itself require Shopify Plus whichever app you use - it's a Shopify platform restriction, not a limitation of either app. Both Selleasy and Rebuy run post-purchase and thank you page offers on any Shopify plan.
