Gravity vs Modern Mern
Compare Gravity 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
Gravity
Gravity is a full‑stack boilerplate for JavaScript/TypeScript projects combining a Node.js backend with a React (or React Native) frontend designed to give developers a head‑start when building SaaS applications. It aims to deliver a working foundation so that you don’t need to assemble all the plumbing (auth, billing, database, UI, API) from scratch. The boilerplate includes support for multiple databases (like Postgres, MySQL, MongoDB, MariaDB and possibly others) which gives flexibility depending on your data/storage preferences. There is also a full “stack” support: server (Node.js + Express/API backend), web client (React + Tailwind or similar), and optionally native mobile clients (via React Native), which helps if you want a unified codebase for web + mobile. Beyond the core stack, Gravity claims to bundle SaaS‑ready features: authentication (email/password, magic links, social logins, 2FA, account security), subscription & billing support (with free plans, trials, seat‑based or usage billing), and a library of UI components & views (dashboard, admin tools, layout components, responsive UI, dark mode, etc.). Gravity also offers a “website/landing page template” (built with a static‑site generator + modern site tooling) useful for marketing, landing pages, pricing pages, etc. — thereby giving you both the “app core” and “public‑facing site” foundation.
