Outputs a single self-contained HTML file. Why this exists: Building a checkout flow from scratch is tedious. You need form validation, responsive layout, accessible labels, step navigation, price formatting, coupon handling, and a clean order summary — all without a CSS framework. This tool generates a production-ready checkout page you can customize, saving hours of boilerplate work.
