our call
Start with Subbyx — highest vibe code, weakest moat.
Sticky.io
Basic recurring billing logic using Stripe is easy to build with AI, but Sticky.io handles multi-MID processing, cascade routing, card account updates, and PCI vaulting. Migrating vaulted payment tokens away from a custom setup when gateways decline transactions is a compliance nightmare.
you can rebuild
- Basic subscriber portal for pause, skip, and swap
- Subscription catalog and discount code management
- Recurring order schedule generation
- Basic email notifications for upcoming rebills
- Standard churn reporting and dashboard metrics
what you lose
- Multi-MID and gateway cascade routing engine
- PCI Level 1 compliant token vaulting outside of standard gateways
- Visa/Mastercard Account Updater (VAU/ABU) integration for expired cards
- Sophisticated decline recycling and smart dunning sequences
- Built-in chargeback protection software integrations
real moats
- PCI-DSS compliant payment token vault across multiple gateways
- Pre-built integrations with merchant processing gateways and fraud tools
- Historical transaction routing data for decline optimization

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.
