Quick Overview

FlutFast
FlutFast is a commercial Flutter boilerplate that provides a full foundation for mobile apps, combining frontend, backend integration, and essential SaaS-style features. It includes pre-built UI components, navigation and state management, authentication flows, database connections, push notifications, and monetization support via in-app purchases or subscriptions. The backend integrates with Firebase or a Node/TypeScript server, while the frontend follows modern Flutter architecture with responsive layouts and componentized design. FlutFast also includes hooks for AI/ML integrations and analytics, offering a structured starting point for developers building cross-platform mobile applications. The project delivers pre-configured infrastructure and architecture, including database models, routing, and payment logic, all wired together according to best practices in Flutter development.

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.
