Zoorix and Sleek Bundles Upsell occupy the same shelf: multi-format apps combining bundles, volume discounts and cross-sells so you don't run three separate tools. That makes this the closest pairing in the series.
Rather than quote pricing and feature lists that change month to month, this guide sets out exactly what Sleek Bundles Upsell ships and gives you the five questions that actually separate bundle apps. Zoorix's current answers are on its App Store listing — read them from the source rather than from a competitor's blog.

The five questions that decide it
When format coverage is comparable, rows one, two and four decide it — how the discount reaches checkout, what a kit looks like in the cart, and whether the widget owns your product page.
What to check | Why it decides it | Sleek Bundles Upsell |
Discount method | Determines whether the discount survives a cart edit and whether it blocks your customer's own code. The one merchants discover last. | Shopify Functions (native automatic discounts) |
Kit checkout | One merged line, or one row per component? Shoppers who see five rows where they expected one product assume something broke. | Single line via Cart Transform API |
Format coverage | Two apps covering the same ground means two fees and two widgets that can discount the same cart independently. | 8 bundle types on one subscription |
Page ownership | Some apps hide your native buy button and render their own — fine until a theme update. | Companion mode: rides your theme's own Add to Cart |
Languages | An English-only widget leaks conversions at the exact moment you're asking for a larger order. | EN, DE, FR, ES, PT-BR |

Under the widget
Native discounting. Every bundle compiles to a Shopify Function — the platform's own automatic-discount layer. Shopify recalculates it on each cart change, so edits can't strand it; no discount code is consumed, so a customer's own code still works alongside it.
Theme-native rendering. Adapters for Dawn, Horizon and the Archetype family (Impulse, Motion, Streamline, Expanse, Fetch, Gem) mean cart updates render instantly rather than forcing a reload. The widget inherits your theme's typography and exposes design tokens for corner radius, row gap, image radius and CTA scale, plus a built-in dark palette.
Placements. Product page, cart drawer, and post-purchase.
So which one?
These two are closer than most pairings, and a reader would be poorly served by pretending otherwise. Where Sleek Bundles Upsell pulls ahead is the mechanics: native Functions discounting, Cart Transform kit merging, and a cart-drawer upsell that installs itself.
Run both through the five questions above and the right choice for your store usually becomes obvious.
