Hi Product Hunt! 👋 I built Luhnify to solve a common friction point in software development: validating IDs, VATs, and passports (ICAO 9303) usually meant relying on heavy, slow, or privacy-invasive third-party services. Luhnify is designed around three core principles: ⚡ Ultra-fast responses: Under 100ms latency. 🔒 Privacy by Design: Zero-PII storage. We perform mathematical checksum and format verification without retaining personal data. 🌍 Global coverage: Built-in validation rules for 200+ countries. Whether you're building a fintech app, e-commerce checkout, or SaaS onboarding flow, Luhnify keeps your validation logic clean and GDPR-compliant. I'd love to hear your thoughts on the developer experience, API documentation, or features you'd like to see added!
