SaaS Boilerplate is a starter template for building full-stack SaaS applications with Next.js, Tailwind CSS, Shadcn UI, and TypeScript.
The template addresses the challenge of bootstrapping a production-ready SaaS application by providing pre-built infrastructure for common requirements. It includes authentication via Clerk, multi-tenancy with team support, role-based access control, internationalization, a landing page, user dashboard, form handling, SEO optimization, error reporting through Sentry, and user impersonation capabilities. The stack uses Drizzle ORM for type-safe database operations across PostgreSQL, SQLite, and MySQL, with testing handled by Vitest and Playwright for unit, integration, and end-to-end coverage. Code quality is maintained through TypeScript, ESLint, and Prettier, while deployment and continuous integration are managed via GitHub Actions.
Developers building a new SaaS product or needing a flexible foundation should consider this template if they want to avoid reinventing authentication, multi-tenancy, and permission systems. It suits teams comfortable with Next.js and React who value a TypeScript-first approach and modular UI components. The template is positioned as production-ready, meaning it can serve as a starting point for applications intended for real users rather than a learning exercise.
The project maintains active development with regular updates to its core dependencies and features. The codebase demonstrates consistent attention to testing infrastructure, with both unit and end-to-end test coverage integrated into the workflow. Documentation is comprehensive, including a live demo environment that showcases the authentication and multi-tenancy system in action. The project accepts community contributions and maintains clear code standards through automated tooling.
