Gravity vs KAppMaker

When choosing between Gravity and KAppMaker, 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 KAppMaker?

KAppMaker is a cross-platform mobile app boilerplate built on Kotlin Multiplatform and Compose Multiplatform, designed to provide a single codebase for creating native Android and iOS applications. It delivers a structured foundation with pre-wired user authentication, subscription and in-app purchase support, push notifications, local data storage, and UI navigation scaffolding. The boilerplate integrates modern development tools such as Ktor for network requests and dependency injection, along with a shared project structure that enables rapid screen creation, code reuse, and deployment across platforms. By offering a ready-to-use architecture, KAppMaker reduces the initial setup and wiring of core app functionality, while still allowing developers to extend or customize the codebase. Its focus on Kotlin Multiplatform makes it suitable for developers or small teams aiming to launch production-ready mobile applications efficiently without duplicating work for Android and iOS.
