Rebuy is a personalization and upsell engine for Shopify. It uses AI to recommend products at the moments that matter, in a smart cart, at checkout, and after purchase, so shoppers see relevant extras and complete a larger order. The goal is a higher average order value from the traffic you already have.

Beyond recommendations it adds bundles, frequently bought together, volume discounts, and A/B testing, plus a customizable slide out cart. It connects to tools like Klaviyo, Attentive, and Recharge, so upsells can tie into your email, SMS, and subscription flows rather than sitting on their own.

Our take

Where it shines: Lifting average order value across the whole funnel. Rebuy places smart recommendations and upsells in the cart, at checkout, and post purchase, driven by AI rather than a fixed rule. Its smart cart and A/B testing let you tune what shows and measure the lift, which is why it rates 4.7 out of 5 across hundreds of reviews.

Who it suits: Established brands with enough traffic and catalog for personalization to pay off. In our data the stores running Rebuy carry large app stacks, around a dozen tools, and it shows up often on subscription and supplement brands where repeat orders and bundles matter. A small store with few products has less for it to work with.

Where to be careful: Cost scales with your volume, so the price climbs as you grow, and you should weigh the fee against the actual order value lift. It is also easy to overdo: too many upsells clutter the buying experience and can annoy shoppers, so test placements rather than turning everything on.

Worth knowing: Rebuy is the powerful, higher end option next to simpler upsell apps and Shopify's own recommendations. It earns its place once a few percent of extra order value is real money for you. If you just want a basic related products block, a lighter app will do the job for less.

How this data works

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 →
