happy-transform
Velocitix AgencyTransform this single-file HTML SEO spintax tool into a fully functional, production-ready SaaS application. Keep the exact same dark theme UI, design, and core client-side logic, but build a robust backend for it. Add user authentication (signup, login, dashboard), a database to manage user sessions/data, and integrate Stripe subscription billing so users must pay monthly to access and use the tool. Ensure the application is secure, scalable, and ready for public launch
