This guide reviews leading Shopify Frequently Bought Together apps including Fly Bundles, Frequently Bought Together (Code Black Belt), Wiser, Frequently Bought Together FT (Fether), WS: Frequently Bought Together (Webrex Studio), Also Bought (Code Black Belt), Addly, and K: Cross Sell + Related Products, evaluating them on recommendation logic, widget flexibility, discount handling, analytics, and scalability.
Shopify Frequently Bought Together apps enable Amazon-style cross-selling by grouping complementary products into a single add-to-cart experience, offering significantly more control and conversion leverage than Shopify’s native complementary products setup.
Overall, the apps vary in approach: some focus on mature, low-maintenance AI recommendations, others emphasize AI autopilot and bundle-building flexibility, while broader recommendation engines extend FBT across the full customer journey.
The guide concludes that Fly Bundles stands out as the most complete Shopify Frequently Bought Together app due to its advanced AI logic, high widget customizability, built-in discount visibility, layout flexibility, scheduling, and scalable pricing.
Shopify Frequently Bought Together apps help merchants replicate Amazon-style product bundling by recommending complementary items directly on product pages (PDP). These upsells increase average order value by reducing friction and surfacing relevant add-ons at the right moment.
While Shopify offers basic product recommendations, native functionality lacks advanced discount logic, analytics, and customization. Also, visually, one cannot display specific discounts on these frequently bought together products, and the UI is restricted by your Shopify theme. This is why dedicated Shopify Frequently Bought Together (FBT) apps are essential for creating high-converting FBT bundles and upsells.

Limitations of Setting Up Frequently Bought Together on Shopify Without An App
What Is Possible with Shopify Native
Shopify allows merchants to display basic frequently bought together or complementary product recommendations using supported themes and the Search & Discovery app.
Stores can show automatically generated or manually selected related products on product pages, manage recommendations directly from the Shopify admin, and run this setup without additional app costs.
For simple cross-sell use cases, this provides a lightweight starting point.
Why Shopify Native Falls Short
Shopify’s native setup does not support true frequently bought together bundles.
Merchants cannot add multiple products to cart in a single action, apply bundle-level discounts with visible savings, or control quantities, layouts, and selection behavior within the widget.
Recommendation logic is limited to basic co-purchase signals, with no AI personalization, scheduling, or targeting.
Additionally, Shopify does not provide FBT-specific analytics, making optimization difficult as stores scale.
Conclusion
Shopify Frequently Bought Together apps have evolved beyond simple product recommendations. Effective implementations now depend on bundled add-to-cart flows, clear discount visibility, flexible layouts, and logic that works reliably across product pages and checkout. Native Shopify tools cover only the basics, which is why most stores rely on dedicated apps to run consistent and conversion-focused FBT offers.
Among the apps reviewed, Fly Bundles offers the most balanced and complete approach to Frequently Bought Together. Its combination of AI-based recommendations, customizable widgets, built-in discount logic, layout flexibility, quantity controls, and scheduling makes it well-suited for merchants who want a scalable FBT setup without adding unnecessary complexity.
