Gravity vs Next Starter AI
Compare Gravity and Next Starter AI 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.
Key Features

Next Starter AI
Next Starter AI is a full‑stack boilerplate built with Next.js + TypeScript + modern frontend tools, designed to help developers launch SaaS apps, AI‑powered web tools or web applications quickly. It bundles ready‑made integrations for common SaaS and web‑app infrastructure: authentication and user management, payment processing (via Stripe or LemonSqueezy), database setup, AI‑tool integration, email delivery, SEO / metadata configuration, landing pages, blog / content pages, and front‑end UI components giving you a nearly‑complete foundation so you don’t have to wire everything manually. Next Starter AI offers a codebase where payment flows, authentication, database/config setup, UI scaffolding, and essential web‑app plumbing are already implemented. That means you can skip repetitive setup work (user sign‑in/up, billing integration, email and content setup, landing page, blog, etc.) and focus directly on building your product’s features. It also includes templates and components for UI (landing pages, dashboards or web‑app views) and wiring for SEO, analytics/marketing integrations, email/mailing functionality, and options for AI‑tool integration if your app needs it.
