Searching for the best YITH Frequently Bought Together alternatives for your WooCommerce store? You are in the right place.
Amazon famously generates over 35% of its total eCommerce revenue through automated product recommendations—with Frequently Bought Together (FBT) bundle boxes leading the charge. When shoppers can combine complementary items into their cart with a single click, Average Order Value (AOV) increases immediately.
For years, YITH WooCommerce Frequently Bought Together has been one of the go-to solutions in the WordPress ecosystem. However, with an annual license cost of $79.99 per year for a single site—and with each additional merchandising feature (like comparison tables or cart upsells) sold as a separate $79 plugin—many merchants find the cumulative cost difficult to justify.
In this guide, we evaluate the 5 best YITH Frequently Bought Together alternatives for 2026. We compare them on bundling flexibility, pricing, storefront user experience, and server performance impact.
⚡ Quick Comparison: Top FBT Alternatives at a Glance
- 1. SiteSkyline Smart Sales: Best overall free alternative. Full Amazon-style bundle boxes, custom percentage discounts, 1-click cart addition, and sub-15ms transient micro-caching with zero subscription fees.
- 2. WPC Frequently Bought Together (WPClever): Best dedicated standalone bundling tool with a capable free tier.
- 3. Iconic Sales Booster: Best premium checkout-funnel upsell companion ($79/year).
- 4. WooCommerce Product Bundles: Best official extension for complex inventory kits and configurable product packages ($49/year).
- 5. FunnelKit: Best for full-funnel custom landing pages, post-purchase one-click upsells, and slide-in carts ($99–$249/year).
Why Look for a YITH Frequently Bought Together Alternative?
While YITH’s plugin is established, several major factors drive merchants to seek modern alternatives:
- Feature Isolation & High Cumulative Costs: YITH sells eCommerce optimization features as fragmented, standalone plugins. If you want Frequently Bought Together ($79.99), Compare Similar Items ($79.99), and Cart Upsell Messages ($79.99), you quickly face over $240/year in renewals just to match Amazon’s baseline product page experience.
- Database Query Overhead on Large Catalogs: When multiple independent upsell plugins query your database simultaneously on single product pages, server response times (TTFB) degrade unless heavy external object caching is configured.
- Mobile Viewport Clutter: Many legacy bundling plugins render rigid desktop layouts that fail to wrap responsively on modern mobile devices, pushing primary add-to-cart buttons below the fold.
1. SiteSkyline Smart Sales (Best Free All-in-One Alternative)
SiteSkyline Smart Sales is a high-converting, performance-focused merchandising suite built to help WooCommerce merchants maximize Average Order Value without adding technical bloat or monthly costs.
The core philosophy of Smart Sales is unified merchandising synergy. Instead of installing half a dozen separate plugins from different vendors, Smart Sales brings Amazon’s proven conversion stack into a single, cohesive engine:
- Amazon-Style Frequently Bought Together: Displays interactive product thumbnails connected by plus signs, dynamic bundle price updates, and individual item checkboxes.
- Flexible Bundle Discounts: Apply automatic percentage discounts (e.g., “Save 10% when bought together”) that recalculate in real time as shoppers check or uncheck individual items.
- 1-Click Multi-Item Add-to-Cart: Shoppers add the primary product along with all selected bundle accessories into their cart with a single click, bypassing repetitive clicks.
- Sub-15ms Transient Micro-Caching: Computed bundle relationships and pricing structures are stored in WordPress transients, ensuring zero database slowdown during high-traffic flash sales.
- Automated & Manual Pairing Modes: Pair products automatically through real order co-purchase algorithms, or define custom manual bundle pairings directly from the dashboard.
Bonus Advantage: In addition to Frequently Bought Together, the free core plugin includes a Smart Free Shipping Bar with gap-filling upsells, a Compare With Similar Items spec matrix, and Predictive Live AJAX Search—saving store owners hundreds of dollars each year.
The Verdict: If you want the complete Amazon product page experience—including bundles, comparison tables, and predictive search—with zero subscription fees, SiteSkyline Smart Sales is the top free alternative to YITH.
2. WPC Frequently Bought Together (WPClever)
Developed by WPClever, WPC Frequently Bought Together for WooCommerce is one of the most widely used dedicated bundling plugins in the official WordPress repository.
WPClever provides a solid free version that lets you manually assign complementary products to simple items, display a total bundle price, and add products together in one click.
Key Strengths:
- Clean integration with native WooCommerce product edit screens.
- Supports variable products with variation dropdown selectors.
- Affordable lifetime/annual premium upgrade ($29) for advanced layout positioning.
Considerations: The plugin focuses strictly on bundling. If you want free shipping progress bars, product comparison tables, or cart upsells, you must install and manage separate plugins.
3. Iconic Sales Booster for WooCommerce
Iconic Sales Booster is a polished premium plugin from IconicWP designed to capture upsells at multiple stages of the shopping journey.
Along with an Amazon-style “Frequently Bought Together” widget below the product summary, it includes post-checkout cross-sells and an order bump modal that triggers when customers click “Add to Cart.”
Key Strengths:
- High-converting “Customers Also Bought” popover modal after clicking add-to-cart.
- Frictionless post-purchase one-click upsells on the checkout thank-you page.
- Modern, refined styling that looks great on premium fashion and lifestyle themes.
Considerations: Pricing starts at $79/year for a single site, placing it in the same premium price bracket as YITH.
4. WooCommerce Product Bundles (Official Extension)
Sold directly on the official WooCommerce Marketplace, Product Bundles by SomewhereWarm is built for stores selling assembled kits, gift baskets, and customized product packages.
Rather than simply recommending related items, it allows merchants to create composite product types with strict inventory rules, dynamic pricing tiers, and optional accessories.
Key Strengths:
- Deep inventory sync—automatically manages stock across bundled components.
- Ideal for technical product kits (e.g., custom skateboard setups or camera gear packages).
- Backed by the official WooCommerce extension guarantee.
Considerations: Costs $49/year. Setup can be complex for stores that simply want Amazon-style cross-sell recommendations without building formal composite kit products.
5. FunnelKit (Formerly WooFunnels)
For merchants looking to completely overhaul their checkout flow, ফানেলকিট offers a full-suite sales funnel builder for WooCommerce.
FunnelKit includes order bumps, slide-in carts with reward tiers, and frequently bought together modules that can be embedded into custom landing pages built with Elementor or Divi.
Key Strengths:
- Full funnel builder with A/B testing and checkout step customization.
- Modern slide-in drawer cart with cross-sell recommendation cards.
- Detailed conversion tracking and revenue analytics dashboard.
Considerations: Pricing ranges from $99 to $249+ per year, making it an investment aimed primarily at dedicated direct-to-consumer (DTC) brands.
