The 10 Best Add On Apps for Shopify
The top 10 apps merchants see when they search the Shopify App Store for add on, in the exact order the store ranks them. Only Shopify's organic ranking is shown, never sponsored ads.
Updated September 8, 2026 · Organic rankingShopify can already give something away. Its native buy X get Y discount lets the free item differ from the bought one, works on products or whole collections, can be set to a full hundred percent off, and can be limited to particular customers or segments. What it cannot do is put the item in the cart. A discount reduces the price of something the shopper added; nothing in it inserts a line.
That single gap is what this entire category sells. Adding the gift is a change to the cart rather than to a price, which is a different mechanism altogether, and it is why these apps exist alongside a discount feature that otherwise does the job. Worth knowing too that a cart line cannot be made unremovable: every line gets the same remove control, so an app preventing removal is hiding that control rather than using a setting Shopify provides.

What to look for in a Add On app
- Check the native discount first
- If you are happy for the customer to add the free item themselves, buy X get Y already does this for nothing, including a different product as the reward. The app is worth paying for when the adding has to be automatic, so be honest about whether that is the actual requirement.
- Silent add, or ask first
- Putting something in a basket without being asked surprises people, and a surprise at checkout is where trust goes. Several apps offer a prompt instead. That is a real choice about your store rather than a setting, and it is worth making deliberately rather than accepting the default.
- What happens when the qualifying item leaves
- Somebody removes the jacket that earned the free scarf. Does the scarf go too, stay at full price, or stay free? Only some apps handle this, few advertise it, and the wrong answer means shipping gifts to people who bought nothing.

What does the Built for Shopify badge mean?
Built for Shopify
Built for Shopify is the highest level of recognition Shopify awards an app. To earn
the badge, an app must meet Shopify's standards for safety, performance, ease of use,
and proven usefulness: it cannot slow down the admin, storefront, or checkout, must
integrate seamlessly into the Shopify admin, and must demonstrate quality through
installs, reviews, and ratings over time. When comparing similar apps, preferring
ones with the badge is a safe default.
