Hi Product Hunt! 👋 I built CardValidator Pro because I kept needing to quickly validate card numbers and look up BIN data during payment integration work and couldn't find a single free tool that did everything without requiring an API key or storing data. So I built one. It covers credit card validation (Luhn algorithm), BIN lookup with issuing bank and country, IBAN validation, UK sort codes, US routing numbers and SWIFT/BIC codes — all free, all instant, privacy-first. Would love your feedback on what tools or features to add next!
