All In One Dev vs SaaS AI

When choosing between All In One Dev 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 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 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 All In One Dev and SaaS AI.

Both All In One Dev and SaaS AI 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 feature-rich solution with specific capabilities.

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.
