Marshal UI is a comprehensive digital marketplace application built with Next.js 14, demonstrating how to create production-ready platforms where creators can sell digital products with built-in payment processing, authentication, and database management. Created by Jan Marshal as a step-by-step tutorial project, this full-featured marketplace integrates Kinde for robust authentication including multi-factor authentication and passwordless login, Stripe Connect for marketplace payments enabling seller payouts and platform fees, Prisma ORM with Supabase PostgreSQL for type-safe database operations, Tailwind CSS and shadcn/ui for modern, accessible components, Zod for server-side validation ensuring data integrity, Resend and React Email for transactional email templates, and deployment on Vercel for global edge performance. The application features comprehensive authentication flows supporting OAuth with Google and GitHub, passwordless magic link login, multi-factor authentication for enhanced security, seller onboarding with Stripe Connect allowing creators to receive payments, product listing and management for digital goods, secure payment processing with Stripe webhooks for real-time updates, email notifications using beautifully designed React Email templates, and server-side validation protecting against malicious inputs. The marketplace architecture showcases how to handle complex payment flows where platform fees are collected while sellers receive payouts, implement webhook handling for asynchronous Stripe events, design database schemas for multi-sided marketplaces, and build type-safe APIs with proper error handling. This project is invaluable for developers learning to build marketplace platforms like Gumroad or Etsy, understanding Stripe Connect integration for multi-vendor payment processing, implementing modern authentication patterns with Kinde, studying full-stack Next.js 14 application architecture, and creating portfolio projects demonstrating e-commerce expertise. The tutorial format helps developers elevate their skills by walking through real-world challenges in marketplace development.
