Rebuy Smart Cart is a personalization and upsell engine for Shopify, built around a slide-out cart that does more than hold items. It adds AI-driven product recommendations, cross-sells and post-add upsells at the point where shoppers are closest to buying, along with tools like free-shipping bars and one-click add-ons to lift average order value.
The adoption data marks this as a conversion-optimization tool for stores with something to optimize. Rebuy sits around the top 25 apps in our dataset, and the stores running it are substantial: they average well over a thousand products and carry a dozen or more other apps. That fits a store already driving traffic and looking to earn more per order, rather than one still finding its first customers. It appears most on Dawn, with a clear lean toward conversion-focused themes like Prestige and Impulse.
What it does: Rebuy turns the cart into a selling surface, with AI recommendations, cross-sells and upsells aimed at raising average order value.
Who it fits: Its typical store carries a deep catalog and a large app stack, the profile of a business with enough traffic and SKUs for personalization to pay back.
Theme company: It shows up most on Dawn and on conversion-minded paid themes such as Prestige and Impulse, stores that treat AOV as a lever.
Keep in mind: Upsell logic and recommendation rules need tuning to feel helpful rather than pushy, so plan time to set up and test offers rather than switching everything on at once.

This figure comes from live detection: we scan Shopify storefronts and read the apps each one runs, then express it as a share of the 3,500,000+ stores in our dataset. It is a share of every store in our dataset, not just recently scanned stores, so it moves more slowly than the month-over-month figures on our trends page. We report what is currently detected, not historical installs or Theme Store / App Store counts.
Independent by design: rankings are determined solely by live detection data. Affiliate relationships never affect what ranks or how stores are counted. Read the full methodology →
