KEEP — THE UI ISN'T THE MOAT

What you pay Deuna for is not the frontend modal. You pay for PCI-DSS Level 1 secure payment vaulting, real-time smart routing across regional acquirers (Mercado Pago, dLocal, Kushki, Ebanx), and instant access to LATAM local payment methods like Pix, SPEI, Boleto, and OXXO. Building a slick single-page checkout form takes hours with Cursor. Building card tokenization, 3DS 2.0 authentication flows, acquirer failovers, and compliance infrastructure will consume months of dedicated senior engineering time.

Why this verdict

Building a custom frontend checkout UI with AI is straightforward, but Deuna's true value lies in PCI-DSS compliant vaulting, intelligent payment routing across fragmented LATAM acquirers, and localized payment rails. An AI prompt cannot handle PCI compliance audits or maintain direct integrations with regional processors.

The one-shot build promptbuild it on Lovable

Build a custom, lightweight payment orchestration layer and multi-step checkout UI designed for LATAM ecommerce transactions. 1. DATA MODEL: Implement models for Cart, Order, Transaction, PaymentMethod, PaymentAttempt, and GatewayConfig. Store transaction status (pending, authorized, captured, failed, refunded) and gateway-specific response payloads. 2. GATEWAY INTEGRATION LAYER: Create adapter interfaces for two payment providers: Stripe (Credit Cards) and Mercado Pago (Pix / Local Payments). Ensure abstract gateway interface methods: tokenize(), authorize(), capture(), and refund(). Do not store raw credit card numbers; rely on provider tokenization or client-side SDK elements. 3. ROUTING & FAILOVER LOGIC: Build a routing engine that checks payment currency and country. Direct Brazilian BRL transactions using Pix to Mercado Pago; route USD/MXN credit card transactions to Stripe. Implement a basic fallback mechanism: if the primary card gateway returns a 5xx or server timeout, attempt authorization through the secondary gateway. 4. ASYNCHRONOUS PAYMENT HANDLING: Implement webhooks endpoints for listening to offline payment events (e.g., Pix payment confirmation). Ensure idempotency by tracking unique webhook event IDs before updating Order status to 'paid'. 5. FRONTEND CHECKOUT UI: Build a responsive Next.js checkout component that dynamically renders available payment methods based on selected shipping country. Provide clean error messaging when payment authorizations are declined. OUT OF SCOPE: Custom PCI card vaulting, 3DS2 native SDK building, and multi-currency bank payouts.

What you keep, what you lose

The honest trade of rebuilding it yourself.

What you can actually replace

✓Single-page embedded checkout UI widget
✓Address validation and country-based field formatting
✓Order creation and status webhook dispatcher
✓Basic rule-based payment gateway toggle per currency
✓Coupon code and discount application backend logic

What you lose

×PCI-DSS Level 1 compliant credit card token vaulting
×Pre-built native API bridges to 20+ LATAM processors and banks
×Cross-merchant recognized buyer network for 1-click checkout
×Dynamic transaction routing to optimize authorization rates
×Automated reconciliation for asynchronous offline payments (OXXO/Boleto)

Why people still pay — the real moats

Moats

— PCI-DSS Level 1 certification and hardware security module tokenization infrastructure
— Direct integrations with fragmented Latin American acquirers and local clearinghouses
— Cross-merchant saved-card network accelerating repeat checkouts across LATAM

Hard parts

— Implementing 3D Secure 2.0 challenge protocols across heterogeneous LATAM issuing banks
— Building safe token storage compliant with PCI-DSS requirements without vendor vaulting
— Managing complex asynchronous payment status callbacks for cash and transfer rails
— Engineering low-latency payment router failovers during acquirer downtimes
— Undergoing annual SAQ-D or QSA PCI-DSS compliance audits
— Negotiating and maintaining active merchant accounts across multiple LATAM PSPs
— Handling cross-border currency conversion, local tax receipts, and fee settlements
— Updating payment integrations whenever regional processor API specifications change

Network effects you cannot generate

— Shared LATAM buyer profiles allowing shoppers to check out with one click across any Deuna merchant store.

FAQ

+Can I really replace Deuna with an AI-generated app?

NO — PAYMENT VAULTING AND LATAM ACQUIRER INTEGRATIONS CANNOT BE PROMPTED. Building a custom frontend checkout UI with AI is straightforward, but Deuna's true value lies in PCI-DSS compliant vaulting, intelligent payment routing across fragmented LATAM acquirers, and localized payment rails. An AI prompt cannot handle PCI compliance audits or maintain direct integrations with regional processors. An MVP takes roughly 2-3 weeks; matching the product properly is closer to 12-18 months, due to PCI-DSS Level 1 certification, token vaulting, and maintaining dozens of LATAM PSP integrations..

+How long does it take to rebuild Deuna?

A usable internal version: 2-3 weeks. A version you would sell or bet a business on: 12-18 months, due to PCI-DSS Level 1 certification, token vaulting, and maintaining dozens of LATAM PSP integrations., mostly spent on implementing 3d secure 2.0 challenge protocols across heterogeneous latam issuing banks.

+What do you actually lose by leaving Deuna?

PCI-DSS Level 1 compliant credit card token vaulting Pre-built native API bridges to 20+ LATAM processors and banks Cross-merchant recognized buyer network for 1-click checkout

+Is it legal to build a Deuna alternative?

Building a competing product with your own code is normal competition. Copying their code, trademarks, brand assets or scraping their platform is not. Use the prompt to build your own implementation of common features.
