Good to know.

QSortby is a Shopify app that uses data and algorithms to automatically reorder products inside your collections and personalizes product display per shopper. It pushes bestsellers to the front and demotes sold-out products automatically.

You pick or create a collection, attach a sorting strategy (based on sales, inventory, shopper behavior...), and QSortby continuously updates product order and personalizes the display for each visitor.

No code edits. QSortby writes the order to your own Shopify collections, and anything shown on the page — the Best Sellers, For You, Bought With and Goes With sections, the cart upsell, the free-shipping bar — comes from the QSortby app embed and sections you switch on in the theme editor. Nothing to paste, nothing to maintain when the theme updates.

Stores that want their collection pages to stay aligned with real-time inventory, sales trends, and shopper behavior.

Two steps: switch the QSortby app embed on in your theme editor, then sort one collection from a starter recipe — Best selling, Trending now or New & selling. The in-app guide has 33 short walkthrough videos, one per screen, and setup help is free on every plan.

Yes. Every install gets 10 days of every feature (the Growth plan) with no card, then settles on the Free plan and keeps running: one collection ranked in real time, sold-out demotion, the cart upsell and free-shipping bar, A/B testing and revenue attribution. Free is a real $0 plan, not a trial. When you pick your first paid plan, it starts with its own 7-day free trial.

Every order and stock change is scored within seconds. Each collection is then re-published on the schedule you pick — every 5, 15, 30 or 60 minutes, every 6 hours, or a custom interval — on every plan, including Free. Change the rule any time and the next run uses it.

Sales, inventory, trending products, and shopper behavior — plus more.

Different visitors can see a different product order in the same collection, based on their browsing/purchase behavior — instead of one fixed order for everyone.

It automatically pushes sold-out or out-of-stock variants down so they don't occupy prime real estate shoppers can't actually buy.

Yes. Goes-with rules keep the products you choose — by vendor, type or tag — side by side through every re-sort, while the collection still follows its ranking rule. Drafting rules is free; publishing them to your storefront starts on the Starter plan.

Judge.me connects in one click and syncs reviews into QSortby. Fera, REVIEWS.io and Stamped are read from the metafields they already write — nothing to connect. Either way, review score becomes a ranking signal (“Top rated”) straight away.

Both connect from Settings → Integrations today; the data flows that use those connections are rolling out in stages. Attribution already reaches those tools another way: influenced orders are tagged in your Shopify admin, so any tool that reads order tags can segment on them.

Yes — AI connections, on Pro and Growth, rolling out in stages. QSortby exposes an MCP endpoint for your store, so an assistant like Claude or ChatGPT can read your collections, why a product ranks where it does, influenced revenue, product movers, experiments and the intent mix. Connections read by default; the store owner decides who may connect and whether an assistant may set up drafts (test-mode collections, unpublished logic, switched-off upsells) or ask for an A/B test that a person then approves in the app. Nothing goes live without you, and no shopper personal data is exposed.

Yes. The app gives you analytics to track the impact QSortby has on your store, along with insights into customer behavior.

Use the chat in the app or on this site, or email hello@qdn.vn. We reply within one business day, and setup help is free on every plan.

Billing is handled through Shopify — you can upgrade, downgrade, or cancel from your Shopify admin.
