All In One Dev vs SaaS UI

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

Saas UI is a premium starter kit / boilerplate built on Next.js (with React + TypeScript) designed specifically for building SaaS and B2B web applications quickly and with solid structure. It pairs a rich UI/design system with the backend scaffold and common SaaS plumbing so you don’t have to build everything from scratch. Right away you get a full-featured component library and design system prebuilt UI components, themes, responsiveness, dark/light mode support all optimized for building dashboards, admin panels, web apps or SaaS products. On the functionality side, Saas UI ships with support for user authentication (login/signup, social login options, account management), workspace/team/organization support (workspaces, team invites, role-based access), subscription & billing flows with Stripe (subscription plans, per‑seat or team‑based billing, metered usage and entitlement management), and built‑in support for multi-tenancy / per‑workspace billing/perms. The stack includes a modern backend API layer (via tRPC), a database setup that works with PostgreSQL (and other options), and a dev environment optimized for productivity (TypeScript, Turborepo/monorepo friendly configuration, sensible defaults for linting/formatting).
