Monster Cart alternatives: cart drawer apps compared

Monster Cart is built around reward bars and free gifts. Here are four other cart drawers to consider, with pricing and strengths.

Key takeaways

  • Monster Cart is a good free start for low-volume stores.
  • UpCart offers the most design control with custom code.
  • iCart gives you several cart layouts.
  • Amose pairs its cart drawer with bundles and post-purchase.

About Monster Cart

Monster Cart combines a slide cart, progress bar rewards, one-tick upsells and product page volume discounts. It's free up to 50 orders, then plans start at $9.99/month and scale with your order count.

It's a good app. Merchants usually compare alternatives for one of these reasons:

  • Your order volume is growing and order-based pricing follows.
  • You need the app in more languages than English.
  • You want full product page bundles and post-purchase offers, not only volume discounts.

How to choose

  • Count your orders: order-based plans grow with traffic, revenue-based plans grow with results.
  • Test on mobile: most carts are opened on a phone, check the checkout button is always visible.
  • Check compatibility with your bundle, subscription and gift apps, or use one app for all three.
  • Measure average order value and conversion for two weeks before and after the switch.
