It covers the key upsell moments from one app — frequently bought together and related-product widgets on product pages, add-ons and cross-sells in the cart drawer, and one-click post-purchase offers — all customizable with no code and backed by funnel analytics. A genuine free plan and a 5.0 rating from 2,150+ reviews (with support merchants single out by name) make it an easy, low-risk way to lift AOV.

Beyond that breadth, its highlights are ready-made offer templates — cross-sell, upsell, service add-ons, and free gifts — collection-wide offers, and a Smart Auto-Upsell mode that uses Shopify's AI to pick the most relevant product for you. The newer slide cart adds built-in offers and a free-shipping rewards bar, and as a Built for Shopify app it brings unlimited upsell revenue with no extra commission and no hit to page speed.

Its draw is range at no cost: volume discounts and quantity breaks, AI-powered frequently bought together, and fixed, mix-and-match, and build-a-box bundles, all from an easy no-code builder you can style to your brand. AI even suggests bundle types from your setup idea and adapts offers to customer behavior in real time — and with a 5.0 rating from 1,100+ reviews and 24/7 support, it is a low-risk way to raise AOV.

It packs in a full range of placements — Amazon-style bundles, product-page cross-sells, cart funnels, and post-purchase and thank-you-page offers — all through widgets designed to stay unobtrusive. Multi-language and multi-currency support suit international stores, and a real standout is the free setup assistance over Zoom, chat, and email, which helps explain its 1,551 five-star reviews.

Its real strength is range: fixed, mix-and-match, multipack, BOGO, and subscription bundles, plus quantity breaks and volume discounts you can set by product or collection. The no-code builder matches offers to your brand, built-in A/B testing and a revenue dashboard show what is working, and as a Built for Shopify app it stays fast and native — which, alongside famously responsive live chat support, helps explain its 5.0 rating from 4,440+ reviews.

Its real strength is range — frequently bought together, mix-and-match and volume bundles, BOGO offers, and both AI and manual recommendations, all from one app. A native cart drawer, custom CSS, and multi-currency and multi-language support make it easy to match your storefront, and there is a free plan to start, which is why merchants rate it so highly for value and ease of setup.

The standout is its recommendation engine — frequently bought together, related products, and handpicked picks — paired with upsell placements at the cart, checkout, and post-purchase. Built-in A/B testing and detailed analytics then let you see exactly what is working and fine-tune your offers from there.

Built by Code Black Belt, it is one of the most established recommendation apps on Shopify, using an AI algorithm to surface Amazon-style frequently-bought-together bundles that customers add in a single click. You also get custom and fixed bundle options, Shopify POS compatibility, and multilingual support — all for a flat $9.99/month with no revenue share, backed by more than 2,300 reviews.

It is one of the few apps to cover the entire funnel — product page, cart, and thank-you page — and backs that with genuinely advanced tools: a funnel builder, A/B testing, an AI autopilot that picks the best offer, and even subscription upsells. Best of all, the free plan includes every feature, so you can run a complete upsell stack from a single app.

Its signature is true one-click upsells — customers accept an offer without re-entering payment details — so both pre- and post-purchase offers convert smoothly. On top of that you get unlimited offers and free upsells through the Shop app, extending your reach at no extra cost.
