  • Slide cart, in-cart upsell and shipping progress bar in one component
  • 5.0 across 1,100+ reviews
  • Free plan to validate on your theme first
Trade-offs
  • Replacing the cart drawer is the most theme-coupled change in this index — test on a duplicate theme
  • Conflicts with other cart apps are common

What "Free plan available" actually means

A free tier with usage or feature caps, and a paid upgrade above them. The most predictable model in this category: you can see the wall before you hit it, and the free tier is usually enough for a small store.

Whatever the label says, the calculation is the same: a upsell & cart drawer app has to lift revenue by more than it costs. Our break-even calculator works out the lift you would need against your own orders and margin — for most stores it is a fraction of a percent, which means the subscription is rarely the real question. The payload the app adds to every page load usually is.
