our call
Start with Submarine — highest vibe code, weakest moat.
Submarine
Submarine sits between payment vaults, Shopify Subscription APIs, and enterprise headless checkouts. While setting up a basic recurring order trigger with Claude takes days, maintaining multi-gateway PCI compliance, zero-downtime token migrations, and resilient dunning at scale requires a dedicated backend team.
you can rebuild
- Fixed-interval subscription contract creation and scheduling
- Customer portal for order skips, pauses, and delivery date adjustments
- Transactional event webhooks for Klaviyo subscriber notifications
- Basic discount application on recurring orders
- Subscription product bundle configuration UI
what you lose
- Multi-gateway payment token vaulting and cross-processor payment routing
- PCI-DSS compliant payment token handoffs across custom checkouts
- Deep synchronization with Shopify Subscription Contracts GraphQL API
- Intelligent retry and dunning logic with automatic card update feeds
- Enterprise headless payment tokenization hooks
real moats
- PCI-DSS compliant tokenization infrastructure for multi-processor stores
- Deep architectural integrations with Shopify Subscription APIs and gateway vaults
- High switching cost and financial risk involved in migrating live payment tokens

- Kill Bill Apache-2.0
- Active Merchant MIT
Subskribe
Subskribe unifies quote-to-cash, deal approval workflows, and subscription billing for enterprise B2B sales. Building a simple PDF quote generator is easy, but replicating audit-ready ASC 606 revenue recognition, coterminous mid-contract amendments, and two-way CRM/ERP sync requires massive domain-specific engineering.

- Standard discount percentage approval workflows
