About
Rebuy
Rebuy has become one of the most widely adopted personalisation engines in the Shopify ecosystem because it solves revenue expansion in a way that feels native to the shopping experience rather than bolted on. Smart upsell widgets, cross-sell carousels, and post-purchase offers are all driven by AI recommendation logic that improves as your order data grows. The no-code configuration means merchandising teams can build and adjust rules without engineering involvement. It integrates cleanly with Klaviyo, Gorgias, and most of the major Shopify stack, which limits the integration friction that often slows tool adoption. AOV lift is the primary metric to watch, and most brands see meaningful movement within the first few weeks.
Justuno
Justuno combines pop-ups, product recommendations, and upsell banners in a single platform with an AI personalisation layer that adapts what each visitor sees based on their behaviour and profile. The recommendation engine is the strongest feature: it surfaces relevant products at the right moment in the customer journey, which drives average order value without requiring manual merchandising rules. The pop-up builder is competent but not the most intuitive in the category. Justuno is better suited to brands that want a unified personalisation tool rather than separate point solutions for pop-ups and recommendations. For stores generating over $2M annually with enough SKU depth for recommendations to be meaningful, the AOV lift from the recommendation layer typically delivers strong ROI.
