Full Stack Kit vs Modern Mern
Compare Full Stack Kit and Modern Mern side-by-side. We've analyzed features, pricing, and capabilities to help you choose the best boilerplate for your SaaS project.
Quick Overview
Full Stack Kit
Full‑Stack Kit is a paid full‑stack boilerplate / template for modern web apps, built around Next.js (version 15), TypeScript, Prisma (with PostgreSQL by default, but supporting other databases), and Tailwind CSS (or comparable styling). The template aims to provide a ready‑to‑go foundation so developers don’t have to implement common boilerplate features from scratch. Full‑Stack Kit bundles typical “standard web application infrastructure”: authentication (email/password, OAuth, magic‑link), role‑based authorization, a built-in admin panel for user and content/announcement management, billing/subscriptions via Stripe (with subscription management, invoices), multi-language support (internationalization), landing‑pages/templates, user dashboards, and a set of UI/layout components for marketing pages, dashboards, and more. It’s positioned as a “launch‑fast” boilerplate: you get a structured, clean, extendable codebase with authentication, billing, UI scaffolding, admin & user management, which lets you focus on crafting the unique parts of your product rather than reinventing the foundation.
