Gravity vs SaaS AI

When choosing between Gravity and SaaS AI, it's essential to understand the key differences that make each boilerplate unique. Both are excellent choices for building SaaS applications, but they cater to different needs and development approaches.

What is 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.

Developed by Kyle Gawley, Gravity has become a popular choice among developers looking for a reliable starting point for their SaaS projects.

What is SaaS AI?

SaaSAI is a boilerplate built on Next.js designed for developers who want to build AI‑powered web apps or SaaS products fast. Its purpose is to deliver a ready‑to‑use foundation so you don’t have to spend weeks wiring up authentication, database, payments, UI and basic SaaS infrastructure. When you start with SaaSAI, you get a project laid out with core pieces already connected: login/auth flows, database setup, payment/subscription management, UI scaffolding, and structure for AI‑app logic, which helps skip a lot of boilerplate overhead. The kit is marketed as especially suited for “AI web‑apps,” implying that it expects you might build features that rely on machine‑learning or AI integrations, while still keeping the standard SaaS skeleton ready. Choosing SaaSAI means locking into its stack and conventions your project will rely on the setup and tooling the boilerplate uses. That’s a good fit if your product roughly matches a typical SaaS or AI‑powered web app pattern; if your needs diverge (e.g. custom backend, highly bespoke architecture, different payment model), you may need to adapt or replace parts of the boilerplate.

Created by SaaS AI, SaaS AI offers a robust foundation for building scalable SaaS applications.

When building a SaaS application, choosing the right payment integration is crucial for monetization success. Let's compare the payment options available in Gravity and SaaS AI.

Both Gravity and SaaS AI are excellent choices for building SaaS applications. Your decision should be based on your specific requirements, budget, and technical preferences.

Gravity is ideal if you're looking for a feature-rich solution with built-in authentication.

SaaS AI stands out for its competitive pricing and is perfect for developers who need authentication.

Ultimately, both boilerplates will help you launch your SaaS product faster and more efficiently. Review the detailed comparison above, consider your project requirements, and choose the one that aligns best with your goals.
