Rebuy
AI-driven upsell + cross-sell engine for Shopify — cart, PDP, post-purchase, checkout extensions.
Our take
Rebuy is the deepest upsell + cross-sell engine in the Shopify ecosystem with ML-driven recommendations that meaningfully beat static rules. The depth is the cost — setup requires taste to look on-brand and pricing assumes meaningful order volume. For Shopify brands at $50K+ MRR wanting incremental AOV without rebuilding the UX, this is the right answer.
Pros
- Deepest merchandising rule engine in the Shopify upsell category
- ML-driven recommendations beat static rules in production
- 10,000+ Shopify brands — strong category proof
- Cart, PDP, post-purchase, and checkout extension coverage
Cons
- Setup requires taste to look on-brand (default widgets feel generic)
- $99/mo Starter tier assumes meaningful order volume
- $499+/mo Scale tier required for most useful features
- Heavy enough that small brands struggle to configure without help
Best for
- Shopify brands at $50K+ MRR wanting incremental AOV uplift
- Operators with design capacity to make upsell widgets feel on-brand
- Brands willing to invest in ML-driven recommendations
Not for
- Sub-$30K MRR brands (Honeycomb's revenue-share pricing fits better)
- Brands wanting set-it-and-forget upsells (Rebuy needs tuning)
- Operators without design capacity to customize widgets
Pricing
Entry: $99/mo Starter
Mid-tier: $499+/mo Scale
