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.

Does it work on mobile?

Yes, BST is built mobile-first. The widget automatically adapts to screen size and is designed to look great on phones, tablets, and desktops.

Do I need my own Claude API key?
