our call
Start with PayWhirl — highest vibe code, weakest moat.
PayWhirl
If running a custom application using Stripe, PayWhirl is redundant because Stripe Billing handles subscriptions natively. If running on Shopify, PayWhirl provides turnkey integration with Shopify's Subscription Contracts API, which requires significant plumbing to recreate safely.

- Customer portal for skipping, pausing, or canceling subscriptions
- Recurring billing schedule generator
- Product swap and frequency adjustment UI
- Transactional payment reminder emails
- Order generation on successful payment cycles
what you lose
- Zero-code setup for non-technical store managers
- Turnkey alignment with Shopify's native Selling Plans API
- Multi-gateway fallback and vaulting infrastructure
- Pre-built PCI-compliant payment widget embeds
