Show HN: Credit Card Generator for Devs and Testers
I built a free tool to generate realistic-looking credit card details for testing payment forms, checkout flows, and frontend validation.
Key features:
Supports 15+ networks: Visa, Mastercard, Amex, Discover, RuPay, UnionPay, JCB, Maestro, and more
Region-specific formats with a valid Luhn check
Interactive UI with card flip animation
Copy to clipboard or generate a QR code of the card details
No signup, no backend — works offline as a PWA
No tracking or data is stored anywhere
Use case: Testing UIs, building demos, or teaching how payment flows work, without using real card data.
Would appreciate feedback or suggestions from the community!
