Next.js SaaS Template

Technology Stack

Architecture

Next.js SaaS Template follows a modern monorepo architecture with clear separation between frontend and backend services. The Next.js frontend handles user interface and client-side logic while the NestJS API manages server-side operations, authentication, and data processing. Shared packages ensure consistency across the monorepo with unified UI components, TypeScript configurations, and ESLint rules.
