Modern Mern vs ReactApp
Compare Modern Mern and ReactApp side-by-side. We've analyzed features, pricing, and capabilities to help you choose the best boilerplate for your SaaS project.
Quick Overview
Modern Mern
Modern MERN is a full‑stack boilerplate for building SaaS‑style web applications, combining a JavaScript/TypeScript‑based backend with a modern React frontend. Under the hood it uses a MERN‑derived stack (MongoDB, Express/Node.js, React), augmented with modern tooling like Next.js, TypeScript, Tailwind CSS, and Prisma plus optional serverless deployment on AWS.
Key Features
ReactApp
ReactApp is a full‑stack SaaS starter built with React + Next.js + Firebase that aims to help developers launch web applications quickly without wiring everything manually. Its stack combines frontend (React & Next.js), UI styling (Tailwind CSS), backend and hosting (Firebase: authentication, Firestore database, serverless functions, hosting), plus built‑in infrastructure for payments (Stripe), transactional emails (Postmark), and optional utilities like a cookie banner, analytics support, and a chat widget for user interaction. With ReactApp you get a project structure where authentication flows (sign‑up/login/reset), user sessions, secure database, payment/subscription handling, and UI/layout scaffolding are already configured. This lets you skip much of the usual boilerplate: routing, backend setup, admin/user flows and go straight to building custom features.
