#What is SaaSfly?

SaaSfly is a robust, open-source Next.js boilerplate engineered for developers and indie hackers crafting subscription-based SaaS products who crave a head start on boilerplate drudgery to prioritize unique features and user growth. Its core value is delivering a production-ready foundation that handles auth, payments, internationalization, and emails out of the box, slashing setup time from weeks to hours while enforcing best practices for maintainable code. Leveraging the T3 stack (TypeScript, tRPC, Tailwind, Prisma) in a monorepo structure, it's tailor-made for use-cases like building AI-powered tools, CRM dashboards, content platforms, or e-learning apps—anywhere you need seamless scaling, global reach, and monetization from day one.

#Features ⚡

• Monorepo Structure: Organize shared code, apps, and packages efficiently with Turborepo, enabling fast builds and consistent tooling across your SaaS ecosystem.

• NextAuth.js Authentication: Secure user sessions with providers like Google, GitHub, or email/password, including role-based access and session management.

• Stripe Payments: Full integration for subscriptions, one-time charges, and webhooks, with customer portals and invoice handling for global transactions.

• i18n Support: Native internationalization via next-intl for multi-language UIs, complete with locale switching and translation workflows.

• React Email Templates: Craft and send beautiful, responsive emails using React components for onboarding, receipts, and notifications.

• Type-Safe API Layer: tRPC for end-to-end type safety between frontend and backend, paired with Prisma for database ORM and migrations.

• Responsive UI Kit: Shadcn/UI components styled with Tailwind CSS for customizable, accessible interfaces like dashboards and forms.

#Pros ✅
