Verdict on EB

Easy Bundle Builder is the premium choice for merchants who need deeply customizable, gamified bundle experiences. The multi-step flow and build-a-box capabilities are best-in-class, and the SDK access makes it the top pick for stores with developer resources. The pricing is higher than competitors, but justified for stores doing serious bundle revenue. The free Starter plan lets you test the waters before committing.

Verdict on BST

BST is the best option if your primary cross-sell strategy is Amazon-style "frequently bought together" recommendations. The AI-powered suggestions are genuinely smart, and the mobile-first design ensures bundles look great on every device. The free plan is limited to 1 manual bundle, but the Core plan unlocks AI recommendations at a fair price. If you want focused cross-sell rather than a full bundle builder, BST delivers.
