Gravity vs Next.js Subscription Payments Starter
Compare Gravity and Next.js Subscription Payments Starter 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.js Subscription Payments Starter
nextjs‑subscription‑payments is a starter template built on Next.js, integrating backend and billing essentials: user auth, database, and subscription payments designed to help you quickly spin up a SaaS or membership‑based web application. It relies on Supabase for authentication and database management (PostgreSQL under the hood), and on Stripe for payment/subscription processing. The integration includes Stripe Checkout for payments, the Stripe Customer Portal for managing subscriptions, and automatic synchronization of pricing plans and subscription statuses via Stripe webhooks, meaning subscription state (active, cancelled, etc.) and billing plans stay in sync between Stripe and your app database.
