our call

Start with CheckoutJoy — highest vibe code, weakest moat.

CheckoutJoy

Building a single payment form connected to Stripe or Razorpay using Claude takes a few days. However, maintaining API client integrations across 15+ regional payment processors (PayFast, Yoco, Paystack, Flutterwave) alongside reliable webhook fulfillment turns a simple custom build into an ongoing engineering task.

  • Hosted checkout page layout builder
  • Embeddable checkout widgets and popups
  • Custom buyer metadata collection fields
  • Order bump and one-click upsell UI components
  • Basic multi-currency display toggles

what you lose

  • Pre-integrated support for 15+ regional payment gateways
  • Automated webhooks mapping payments directly to platform access rights
  • Out-of-the-box PCI-DSS SAQ-A compliant iframe architecture
  • Managed gateway API key encryption and secure tokenization
  • Automatic retry logic for asynchronous regional payment webhooks
