SaaS AI vs Uni-Stack
Compare SaaS AI and Uni-Stack side-by-side. We've analyzed features, pricing, and capabilities to help you choose the best boilerplate for your SaaS project.
Quick Overview
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.
Key Features
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.
