our call
Start with Shopflo — highest vibe code, weakest moat.
Rally
Rally handles secure payment tokenization, multi-gateway routing, and post-purchase order mutations across platforms. Building a basic React checkout form is trivial; maintaining a PCI-compliant, fault-tolerant payment architecture that processes post-purchase upsells without re-prompting for card details is high-risk engineering.
you can rebuild
- Post-purchase upsell modal presentation and product selection UI
- Custom checkout page layout and visual design elements
- Basic promotional discount and coupon input handling
- Address auto-complete and client-side form validation
- Custom checkout form field injection
what you lose
- Out-of-the-box PCI-DSS compliance isolation for payment processing
- Native post-purchase authorization holding and order modification logic
- Pre-integrated connections to tax engines (Avalara/TaxJar) and shipping rate APIs
- Cross-merchant 1-click user recognition network
- Battle-tested zero-downtime performance during high-concurrency product drops
real moats
- PCI-DSS Level 1 compliance infrastructure and audit coverage
- Deep ecosystem integrations with payment gateways, tax providers, and fraud platforms
- Shared buyer payment token vault across merchant networks

Shopflo
Building a custom checkout UI and cart drawer with AI takes under two weeks. However, Shopflo's primary moat lies in its cross-merchant address auto-fill network via phone OTP and deep local payment gateway failover orchestration. Rebuilding the frontend is trivial, but matching their conversion lift network is not.
