From Luma to React: Redesigning Magento Checkout for 34% Faster Conversions

Magento's default Luma checkout creates a performance bottleneck that directly impacts revenue, especially on mobile devices. This case study demonstrates how replacing it with a modern React frontend delivered a 34% improvement in checkout completion and 39% on mobile—showing that eCommerce platforms built on aging JavaScript architectures leave significant conversion gains on the table. For mid-market merchants struggling with checkout abandonment, the real-world performance delta presented here suggests that frontend modernization, not minor tuning, may be the answer.
