About
The Project
create-e2e-saas is a powerful CLI tool designed for developers who want to skip the repetitive task of building authentication systems. It scaffolds a complete, ready-to-run MERN stack application featuring JWT-based authentication, OTP email verification, and password resets. The generated project uses modern technologies like React 19, Vite, Tailwind CSS 4, and Shadcn/UI for the frontend, with a robust Node.js/Express backend. It's an ideal starting point for SaaS products, hackathons, and rapid prototyping.
