our call
Start with Subify — highest vibe code, weakest moat.
Subbyx
Building a basic Shopify subscription widget and customer portal using Shopify's native APIs is simple with modern AI tools. However, replicating robust payment retry logic, third-party app integrations (Klaviyo/Gorgias), and data migration tools makes a full custom replacement high-maintenance.
