In 2026, both Cart Block: checkout validator and Kedra Checkout Rules are Shopify apps designed to give merchants greater control over their checkout process, particularly in preventing fraud and unwanted orders. Cart Block positions itself as a comprehensive solution for bot and fraud protection, offering features like a dynamic CAPTCHA and multi-channel support. Its core strength lies in its blocking and validation capabilities based on diverse criteria, along with clear messaging for customers. Kedra Checkout Rules, on the other hand, emphasizes customization and flexibility in the checkout experience, allowing merchants to rename, reorder, and hide shipping and payment methods based on specific conditions, along with the ability to apply conditional shipping discounts.
