What is Open SaaS?
Open SaaS is a comprehensive, open-source SaaS boilerplate template that revolutionizes how developers build and launch their applications. This powerful full-stack framework combines React, NodeJS, and Prisma to deliver a production-ready foundation with pre-configured authentication, payment processing, and AI capabilities. Unlike starting from scratch, Open SaaS provides developers with enterprise-grade features including Stripe and Lemon Squeezy payment integrations, admin dashboards with analytics, and built-in OpenAI integration for AI-powered applications. The template emphasizes developer freedom with no vendor lock-in, allowing deployment anywhere while maintaining full-stack type safety through TypeScript.
How to Use Open SaaS
Open SaaS offers an intuitive development workflow that accelerates your SaaS journey from concept to production. Begin by cloning the open-source repository and customizing the pre-configured authentication system to match your brand. Integrate your preferred payment provider—either Stripe or Lemon Squeezy—using the included setup guides. Configure the admin dashboard with your analytics provider of choice, whether Plausible or Google Analytics, to track user engagement and business metrics. The template's modular architecture allows you to easily extend functionality while maintaining code quality through built-in E2E tests.
To master Open SaaS, developers can leverage the comprehensive documentation and LLM-optimized guides that explain advanced features like AWS S3 file uploads, email sending capabilities, and the Astro-powered blog system. The Wasp deployment tools simplify hosting, or you can deploy independently to your preferred infrastructure. The active Discord community provides support and best practices for maximizing Open SaaS potential in production environments.
