Scored on 10 merchant reviews we hold for Checkout Customizer Ninja, across five checks. Every figure is computed from those reviews — expand any row to see the counts behind it.





Computed from the 10 reviews we hold, with 12-month windows measured to 2026-08. This scores the public review record — it is not a review of the software itself, and a low score often means we hold little evidence rather than poor evidence.

Been using CheckoutNinja for a few months now on our Shopify store and honestly it does what it promises. Setup was straightforward, didn't need to mess around with code or anything. The upsell flow at checkout actually converts way better than what we had before. Only thing I'd say is the UI could be a bit cleaner in the dashboard, took me a minute to find some settings. But support replied within a day when I had a question. Solid app for the price.

what a great app it working just as i should we are very happy with this app and will keep using this

great support, great app

Great help and support .Its working well!

10/10 support and the app functions great

If you're looking for a solution to customize messages and cart limitations at checkout, Checkout Ninja Blocks is the perfect app! We were facing a challenge on our U.S.-based website, and needed to display a custom message for specific products and regions. Checkout Ninja Blocks not only solved the problem but did so seamlessly. The app allowed us to display a message for our U.S. customers and enforce product limits in the cart based on specific criteria. The customization features were incredibly flexible, and the app provided everything we needed, from triggering messages to limiting product quantities during checkout. It integrates perfectly with Shopify, making it easy to manage and adjust. Fantastic support from the Checkout Ninja Blocks team made all the difference. They worked closely with us to create a custom solution that fit our exact needs. Their response time was quick, and they went above and beyond to ensure everything worked flawlessly. If you’re in need of a powerful checkout customization tool backed by fantastic support, I highly recommend Checkout Ninja Blocks. It’s been a game-changer for our store. Install it, test it, and reach out to the support team if you need any customizations—you’ll be in great hands!
