A sticky add to cart on Shopify is a button or bar that stays on screen while shoppers scroll a product page, so they can buy without scrolling back up. You add one with your theme’s built-in option (if it has one) or with an app such as Madgic Sticky Add To Cart (free), Essential Cart Drawer or EA Sticky Add to Cart Drawer.
This guide explains when a sticky button helps, compares five apps on rating, reviews and price, and lists the problems merchants report so you can avoid them.

Quick answer: which sticky add to cart app should you pick?
- You only want a simple floating button, free: Madgic Sticky Add To Cart. It is new, with no reviews yet.
- You also want a slide-out cart with upsells: Essential Cart Drawer. Its free plan includes a sticky add to cart bar.
- You want a sticky bar with a variant picker and a cart drawer in one paid plan: EA Sticky Add to Cart Drawer.
What is a sticky add to cart button, and does it help?
On long product pages, the main add to cart button scrolls out of view once shoppers read photos, reviews and FAQs. A sticky button or bar pins a buy action to the top or bottom of the screen. It matters most on mobile, where product pages are long and thumbs are far from the original button.
It helps when your pages are long and shoppers already want the item. It helps less on short pages, or when it hides content like a chat icon or cookie banner. Test it: compare add-to-cart rate for two weeks before and after.
Check your theme first. Some Shopify themes include a sticky add to cart option in the theme editor. Open Online Store > Themes > Customize, select a product template, and look for “sticky” in the product section settings. If it is there, you may not need an app.

1. Madgic Sticky Add To Cart
We build this one, so keep that in mind. It launched on July 28, 2026 and has no reviews yet. It does less than the other apps in this list: it shows a floating add to cart button on product pages and can send shoppers to the cart or straight to checkout in one tap. You set the icon, color, position, size and label to fit your theme.
Where others are stronger: it has no cart drawer, upsells or variant picker listed. If you need those, Essential or EA is a better fit.
Setup: install from the App Store, choose the button style, color, position and label in the app, pick cart or checkout as the destination, then preview a product page on your phone.
Price: free.
2. Essential Cart Drawer Cart Upsell
Essential Apps’ cart drawer launched in March 2025 and has 1,083 reviews at 5.0. It is mainly a slide cart with upsells, a free shipping bar and a countdown timer, but the listing says it also includes a sticky add to cart bar with product image, variant picker and quantity. The free plan lists “sticky add to cart & countdown timer.”
Price: free up to 30 orders a month; paid plans from $8.99 (99 orders) to $23.99 (499 orders), with more tiers above.
Best for: stores that want a cart drawer and a sticky bar from one vendor and are fine with order-based pricing.
3. EA • Sticky Add to Cart Drawer
EasyApps launched this app in February 2024; it has 215 reviews at 4.9. It bundles a sticky add to cart bar, a side cart drawer with upsells, a rewards progress bar, quick buy buttons and an AI design assistant.
What reviewers complain about: its few low-star reviews are short. One from mid-2026 calls the app clunky and the interface hard to use. The developer replied asking for details.
Price: $9.99 a month with a 7-day trial; free on development stores.
Best for: stores that want several cart tools in one flat-price plan.
4. Sticky Add To Cart Bar Pro
Great Apps Factory has run this app since June 2017. It has 43 reviews at 4.9. The sticky button behaves like your theme’s own add to cart button and supports multiple currencies and languages, plus a skip-to-checkout option.
Price: free up to 500 visitors a month; $3, $5 and $10 a month for 10k, 50k and unlimited visitors.
Best for: small stores that only need the bar and want the lowest paid price.
5. Sticky Add to Cart Bar by CatApp
CatApp launched in June 2025 and has 3 reviews at 5.0, so it is still early. Its useful detail is display rules: show the bar only when the original button is out of view, and target product pages, the homepage or specific collections, on desktop, mobile or both.
Price: free for 1 widget; Lite $5.99 and Premium $9.99 a month.
Best for: merchants who want control over where and when the bar shows.
Common problems merchants report
Low-star reviews of sticky bar and cart drawer apps point to the same few issues:
- Theme conflicts. One merchant said a cart app did not work with Shopify’s Horizon theme. Test on your live theme before you publish.
- Mobile display. A review described the cart looking zoomed in on iPhones. Check iOS and Android, not only desktop.
- Discount mismatch. On one cart app, a discount applied only when the item was added from the drawer, not the product page. If you run offers, test both paths.
- Hard setup. Several reviewers call cart apps clunky to configure. Start with one feature, then add more.

How to choose
- Do you need only a button, or a whole cart? If only a button, pick a light app. Extra features add extra code.
- How is it priced? Essential bills by orders, Bar Pro by visitors, EA at a flat rate. Estimate next season’s traffic.
- Variants: if most products have sizes or colors, choose an app with a variant picker in the bar.
- Mobile first: preview on a real phone. The bar must not cover chat, cookie or review widgets.

FAQ
How do I add a sticky add to cart button in Shopify without an app?
First check your theme settings for a sticky option. If there is none, it takes custom code in your theme files. An app is safer if you are not comfortable editing Liquid and CSS.
Is a sticky add to cart bar good for mobile?
Usually, because mobile product pages are long. Keep the bar small and make sure it does not hide other buttons.
Can the sticky button go straight to checkout?
Yes, in some apps. Madgic Sticky Add To Cart and Sticky Add To Cart Bar Pro both list a skip-to-checkout option.
Will a sticky bar slow my store?
Any app adds some code. Run a speed test on a product page before and after install.
