A free WooCommerce plugin that mines your order history and shows automatic frequently-bought-together suggestions in the cart with one-click add.
When MBA wins
If you want to see and trust the math (support/confidence/lift) behind each recommendation, build real-SKU bundles, run A/B tests, reach customers across multiple storefronts, or expose recommendations to APIs/AI agents, MarketBasketAnalysis is built for that depth while PiWeb is not.
When PiWeb Products Frequently Bought Together wins

Free, single tier. Published on WordPress.org with no paid or pro version listed; fewer than 10 active installs and no user reviews as of mid-2026.
Visit PiWeb Products Frequently Bought TogetherThe honest verdict
PiWeb is a genuinely free, low-friction WooCommerce plugin that does one thing well: auto-mining order history to show frequently-bought-together suggestions in the cart, and for a single store on a budget that may be all you need.
It is very new and lightly adopted (fewer than 10 active installs, no reviews as of mid-2026), so it lacks the track record, support, and configurability of more established tools.
Both products mine real order history and both offer a free WooCommerce tier with one-click cart suggestions, so on basic cross-sell the two genuinely overlap.
MarketBasketAnalysis goes further where it matters for growth: explainable support/confidence/lift you can inspect, real-SKU bundles and formats, A/B testing, and email/Klaviyo recommendations.
If you need multi-platform reach (5 storefronts on one API), agent-native access (REST + 19-tool MCP (18 tools off Shopify) + agentic commerce), or B2B-aware mining and reorder-prediction data, MarketBasketAnalysis is the clear fit; PiWeb is scoped to in-cart WooCommerce suggestions only.
