Best cart drawer for Shopify

A cart drawer is the slide-out cart that opens when someone adds a product, so they stay on the page. On a US Shopify store the drawer is also where free shipping, a gift, and a discount code get decided, before sales tax is calculated at checkout. This guide is for the person who has to pick one drawer and live with the monthly bill.

Best cart drawer for Shopify, by the job

There is no single best cart drawer for every US store. There is a best drawer for a job. Use this table first, then read the two listings we would actually install.

Foxr Cart Drawer & Upsells

Foxr Cart Drawer & Upsells is the first install when the job is a free side cart. The public listing shows a price of Free, a 5.0 rating from 3 reviews, a launch date of October 22, 2026, and the developer FOXR APP in the United Kingdom. The language on the listing is English.

What the listing includes

• A slide cart that opens on add to cart, with templates and custom CSS.
• Cart upsells and cross-sells with discounts, plus buy-more-save-more offers.
• A free gift with purchase, a free-shipping bar, and tiered rewards.
• A discount code field, gift wrap, donations, order notes, a terms checkbox, a shipping estimator, and cart sharing.
• Countdown timers, announcements, loyalty rewards in the cart, and a sticky add-to-cart bar.

That is the feature list a US merchant usually writes on a brief: the shopper can see the shipping threshold, apply a code, and add one more item without a page change. The listing does not name checkout upsell blocks or a post-purchase page. If those slots are the job, use Oxify and read the post-purchase upsell guide.

Three reviews in under three weeks is a thin operating history. The written reviews on the listing are short. Treat the feature list as a spec, install it on a duplicate theme, and check the drawer on an iPhone before you point ads at it. If the drawer fails on your theme, the price being zero does not make it free.

Oxify Cart Drawer & Upsell

Oxify Cart Drawer & Upsell is the paid pick. The live app name is Oxify Cart Drawer & Upsell. The App Store URL still uses the slug ia-cart-drawer-free-gifts. It carries the Built for Shopify badge, a 4.9 rating from 44 reviews, and a launch date of January 12, 2024. The developer on the listing is Oxify App, Panipat, India. Of those 44 reviews, 42 are 5 stars, one is 3 stars, and one is 2 stars.

What you get on every plan

The listing puts the same feature list on every tier: a designed slide cart, an announcement bar with a countdown, a reward bar and free-shipping progress, cart upsells, cross-sells, and frequently-bought-together bundles, cart add-ons and shipping protection, checkout upsell blocks and trust badges, a free gift with an automatic discount, and post-purchase plus thank-you page upsells. The analytics block lists A/B testing, click-through, conversion rate, recommendation performance, and funnel performance.

Checkout blocks on the information, shipping, and payment steps are a Shopify Plus surface. Shopify's own developer docs say those checkout UI extensions are available only to Plus stores. A non-Plus store can still use the drawer, the gift, and the post-purchase page. Confirm the checkout block appears in your checkout editor before you cancel another app.

What it costs in US dollars

Shopify shows a converted price outside the United States. On the dollar listing, and confirmed against the plan labels, the four tiers are below. Each one lists a 14-day free trial. Languages on the listing include English, Spanish, French, German, Italian, Portuguese (Brazil), Danish, and Japanese, which matters if the same US brand sells into Canada or the EU.

Above 1,000 store orders a month, the public tiers stop. Ask the developer for the next band before you promise finance a flat $49.99. The meter is store orders, so a wholesale month can push you up a tier even if the drawer itself added little.

What a US cart drawer has to do

Page-one guides agree on the same parts. A drawer that is only a prettier cart page does not change the order. These are the parts that do.

• A threshold the shopper can see. Free shipping at $75, a gift at $100, or 10% off at $150. One bar, in dollars, tied to merchandise subtotal.
• A gift that adds and removes itself. If the shopper drops under the threshold, the gift has to leave. A gift that sticks is a margin leak.
• A discount field in the drawer. US shoppers hunt for a code before they pay. If the field is missing, they leave to search for one.
• One upsell with a real add button. A row of eight products is a second catalog. One accessory, one variant, one tap.
• A sticky add-to-cart on mobile. Most US paid traffic lands on a phone. If the button is below a long description, the drawer never opens.

Sales tax is calculated in checkout, not in the drawer. Do not write a threshold that assumes tax is already in the cart total. Spell the rule as merchandise subtotal, and match it in the app.

What the drawer costs against contribution

The app fee is the easy number. Contribution is the one that decides whether you keep it. This worksheet uses a made-up US month so you can drop in your own orders. It is not a result from either app.

An extra $24 item on 5% of those orders is 10 units, $240 of revenue, and about $84 of contribution at the same 35% margin. That is roughly four times the $19.99 fee. Foxr's fee in this worksheet is $0, so the same offer only has to clear the cost of a slower theme. The 5% take rate is a target you measure in the app after two weeks. It is not a promise.

If you do not know contribution by product, read ROAS vs POAS before you scale ads into a drawer that sells the low-margin SKU. A higher average order value can still lose money.

Apps with a longer review history

Kaching CartDrawer, Upcart, and Essent show up on nearly every 2026 roundup because they have large review counts and published order-based or flat prices. Those counts are the reason a cautious brand picks them. They are also the reason the prices in a blog from last month are already stale. Open the live listing and sort by the order band you will hit this quarter. We are not repeating a review total we did not read on November 9.

Use that longer history when a failed drawer would stop a sale on a store doing several hundred orders a day. Use Foxr when you want the feature list at no monthly fee and you can watch it for a week. Use Oxify when you want one Built for Shopify app to cover the drawer, a gift, checkout blocks on Plus, and the post-purchase page, and you will accept a bill that follows store orders.

How to install one drawer

1. 01Duplicate the live theme. Install the app on the duplicate. Never edit the published theme first.
2. 02Turn off the theme's cart drawer so two drawers do not open. One drawer per store.
3. 03Set a merchandise-subtotal threshold in dollars. Add one gift that removes itself under the threshold.
4. 04Add one upsell. Give it a variant selector and a discount that is a real Shopify discount, so checkout matches the drawer.
5. 05On an iPhone, add a product, apply a code, and open checkout. Then do it again in a private window.
6. 06Leave it for 14 days. Read add-to-cart rate on the upsell and the change in items per order. Keep the app only if contribution moves.

If the theme fight takes more than an afternoon, that is a Shopify development job, not a reason to install a second drawer app. Two cart apps is how stores get a slow product page and a double-counted gift.

Which drawer to keep

Install Foxr Cart Drawer & Upsells if the requirement is a free slide cart with upsells, a gift, a shipping bar, and a discount field, and you can tolerate a listing that is weeks old. Install Oxify Cart Drawer & Upsell if you want Built for Shopify, a 2024 launch, checkout upsell blocks, and post-purchase in the same subscription, priced from $9.99 to $49.99 by store orders. Skip both if the theme drawer already matches the brand and you have nothing to offer in it. A drawer with no offer is only motion.
