UpCart alternatives: 5 cart drawer apps compared
UpCart is one of the most popular cart drawers on Shopify. If its order-based pricing or feature set isn't right for you, here's what else to consider.
Read articleKey takeaways
- Kaching is a strong product, the main reasons to look elsewhere are price caps and wanting a cart drawer in the same app.
- Bundler has the most generous free plan for simple quantity breaks.
- Fast Bundle and Wide Bundles focus on bundles and add A/B testing.
- Amose bundles plus cart drawer plus post-purchase from $14.99/month, with unlimited revenue at $29.99.
Why merchants look for a Kaching alternative
Kaching Bundles is Built for Shopify. It does quantity breaks, BXGY, bundle upsells and A/B testing very well. So why look elsewhere? Usually for one of three reasons:
- Revenue caps. Plans are based on the additional revenue the app generates: $14.99 up to $1,000, $29.99 up to $5,000, $59.99 up to $10,000 per month. A successful bundle can push you into the next plan quickly.
- Cart drawer and post-purchase. Kaching focuses on the product page, with its cart available as a separate app. If you want bundles, a cart drawer and one-click post-purchase offers under one plan, you'll need to look elsewhere.
- Fewer apps. Every extra app is another script, another bill and another place where offers can conflict.

How to choose
- List the moments you want to monetize: product page only, or cart and post-purchase too.
- Estimate the extra revenue the app will generate, and check which plan that puts you on.
- Install on a development store first, most apps are free there.
- Test on mobile with your real theme before going live.
If you only need quantity breaks, Kaching, Bundler or Wide Bundles are all great choices. If you want the product page, cart and post-purchase in one place, that is what we built Amose for.
