our call
Start with Mollie — highest vibe code, weakest moat.
Mollie
You cannot replace Mollie with an AI prompt because Mollie is an authorized European payment institution with regulated money movement rails. Writing the software layer for checkout widgets or payment orchestration is simple, but software alone cannot process card transactions, settle iDEAL payments, or hold merchant funds.
you can rebuild
- Hosted checkout payment pages and payment links.
- Merchant dashboard UI for manual refunds, customer list, and transaction history.
- Basic recurring billing schedules and subscription state management.
- Webhook dispatch engine with signature verification.
- Multi-currency payment payload normalization.
what you lose
- Access to De Nederlandsche Bank payment institution licensing under PSD2/PSD3 regulations.
- Direct settlement contracts with European acquirers, card schemes, and local APMs.
- Managed chargeback defense mechanisms and automated fraud detection systems.
- Out-of-the-box support for physical hardware POS terminals and Tap to Pay frameworks.
- Automated cross-border SEPA clearing and multi-currency payout reconciliation.
