All In One Dev vs Uni-Stack

When choosing between All In One Dev and Uni-Stack, 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 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.

Developed by Christian Esmann, All In One Dev has become a popular choice among developers looking for a reliable starting point for their SaaS projects.

What is Uni-Stack?

Uni‑Stack is a free, open‑source, production‑ready full‑stack framework for building universal React Native + web apps with a single codebase. It uses modern, type-safe technologies — including Expo (with universal support for iOS, Android and web), Prisma for database management, tRPC for end-to-end type‑safe APIs, and TypeScript for strong typing throughout. With Uni‑Stack you get an integrated stack where routing, UI, database logic, API calls, queries and mutations are all type-safe and unified. It supports multiple UI system options (e.g. Nativewind, Tamagui, gluestack‑ui), giving flexibility in theming and design while keeping a consistent architecture.

Created by ROFI, Uni-Stack 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 All In One Dev and Uni-Stack.

Neither boilerplate includes pre-built payment integrations. You'll need to implement your preferred payment solution manually. Consider using Stripe, Lemon Squeezy, or Paddle for your SaaS monetization.

Both All In One Dev and Uni-Stack are excellent choices for building SaaS applications. Your decision should be based on your specific requirements, budget, and technical preferences.

All In One Dev is ideal if you're looking for a more affordable option with specific capabilities.

Uni-Stack stands out for its comprehensive feature set and is perfect for developers who need specific features.

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.
