Absolutely Not — CartDNA Apps Are Built for Performance and Stability

View Shopify payment Methods 

We understand how crucial speed and reliability are for any online store, especially during the checkout process where even the slightest delay can lead to cart abandonment. That’s why all CartDNA apps are engineered with performance optimisation in mind. You can rest assured that installing and using CartDNA payment apps will not slow down your store or negatively impact your checkout performance

CartDNA apps are built in compliance with Shopify’s Payment App framework and are fully embedded within the native Shopify checkout system. This means they are not external scripts or third-party front-end widgets that could load additional content on your storefront or interfere with your theme. Since our apps do not inject any frontend code or scripts into your live store, they do not affect the loading speed or performance of your product pages, home page, or cart pages.

Checkout Speed Is Unaffected — Optimized API-Based Functionality

All interactions between CartDNA apps and the Shopify checkout happen server-to-server or through Shopify’s secure back-end mechanisms. There are no client-side delays or bottlenecks introduced by our apps. This design ensures a seamless and uninterrupted checkout experience for your customers, even during peak traffic times.

Whether you’re using one or multiple CartDNA payment methods, each operates independently within Shopify’s standardized checkout workflow. The app simply acts as a secure bridge between your Shopify store and the chosen payment provider — without adding weight to your site’s performance or modifying the checkout UI.

Approved by Shopify — Built to Meet Strict Technical Standards

As a Shopify-approved payment application developer, CartDNA follows strict development and security standards enforced by Shopify. Every app undergoes rigorous review by the Shopify engineering team before being approved. This includes benchmarks for load time, performance, security, and customer data protection.

Even if you choose to install multiple CartDNA apps to support different alternative payment methods for various countries or customer segments, your store’s speed will remain unaffected. Since all apps operate independently at the checkout layer and do not run concurrently in your storefront environment, there is no cumulative performance burden on your store.

In Summary

Installing CartDNA apps will not slow down your Shopify store or disrupt your checkout experience. Our apps are designed to work invisibly and efficiently, directly within Shopify’s infrastructure, ensuring that your customers enjoy a fast, smooth, and secure checkout at all times.
