31SaaS vs All In One Dev

When choosing between 31SaaS and All In One Dev, 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 31SaaS?

31SaaS feels like a project built by someone who actually ships products, not someone assembling a checklist of features. The whole thing runs on Next.js 14, and the structure is clean in a way that makes sense the moment you open the repo — the kind of layout you’d probably set up yourself after a few iterations, just without the wasted weekend. The authentication flow, Stripe setup, and email handling are already connected and working, not half-finished stubs. The UI is put together with shadcn and Tailwind, so it looks modern without being overdesigned, and it’s easy to extend without fighting the styling choices. What stands out is that you can start building real features almost immediately. There’s a proper dashboard, a place for marketing pages, a blog engine that doesn’t feel like an afterthought, and small touches like sensible error handling and clean form patterns. It’s not trying to reinvent the wheel — it’s just a solid, well-assembled foundation that saves you from the usual setup grind. If you want a boilerplate that stays out of your way and lets you move quickly without later regretting the shortcuts, 31SaaS is one of the more thoughtfully built options out there.

Developed by Said Hasyim, 31SaaS has become a popular choice among developers looking for a reliable starting point for their SaaS projects.

What is All In One Dev?

AllInOneDev aims to be a “one-codebase-for-everything” template: web, iOS and Android — unifying your frontend and backend so you don’t have to build separate projects for each platform. Under the hood it uses technologies like Next.js (for web), React Native + Expo (for mobile), along with TypeScript, a monorepo via Yarn workspaces, shared UI and logic, styling via NativeWind (tailwind-style for cross-platform) and a folder structure aimed at reuse across mobile and web. The template bundles lots of common “plumbing” out of the box: user authentication (via Firebase Auth), payment integration for both web payments (via Stripe) and in-app mobile purchases/subscriptions (via RevenueCat), analytics & user-tracking, internationalization (multi-language support), push notifications, and a set of default screens/routes (onboarding, login/register, home/dashboard, profile/settings, plus landing/pricing pages for web). In practice this means if you pick AllInOneDev you get a starting point that covers almost everything non-business-specific: cross-platform UI and styling, authentication, payments, analytics, data & backend integration, navigation, and a shared codebase to reuse across web and mobile — which can save you significant development time compared to building each platform separately. However it’s important to keep things realistic. AllInOneDev is a closed (paid) boilerplate, with a license that lets you build unlimited projects personally or with a team (but doesn’t transfer ownership of the boilerplate itself) and you must respect its license terms. By using it, you also commit to its architectural choices: monorepo structure, React-Native + Next + Expo + Firebase/RevenueCat/Stripe stack, styling via NativeWind, Redux Toolkit, etc. That’s fine if you agree with those choices — but if your project needs a drastically different architecture (something more minimal, or different backend, or different payment/infrastructure stack), adapting or decoupling from AllInOneDev might get heavy. AllInOneDev is suitable if you're starting a cross-platform app (web + mobile), want to move quickly, and don’t mind leaning on a ready-made, opinionated stack so you can focus on the actual product logic. If instead you want minimal dependencies, maximum control or want to avoid vendor lock-in (Firebase, RevenueCat, etc.), then a lighter or custom solution might be more appropriate.
