What is Open SaaS?
Open SaaS is a modern, production-grade open-source SaaS starter kit engineered for speed, scalability, and developer autonomy. Built natively with React (App Router), Node.js (Express + Next.js API routes), and Prisma ORM, it delivers a tightly integrated full-stack foundationâpre-wired with secure authentication, battle-tested payment flows, intelligent AI extensions, and a feature-rich admin interface. This isnât just scaffolding: itâs a cohesive architecture where TypeScript enforces end-to-end type safety, database migrations are versioned and reversible, and every layerâfrom frontend routing to backend billing logicâis designed for real-world SaaS requirements. With zero proprietary abstractions and no hidden dependencies, Open SaaS puts you in full controlâdeployable on Vercel, Railway, AWS, or your own Kubernetes clusterâwithout sacrificing security, observability, or extensibility.
How to Use Open SaaS
Getting started with Open SaaS is intentionally frictionless. Fork the repository, run npm run setup to initialize environment variables and database schema, then launch both frontend and backend with a single command. Customize the auth flowâsupporting email/password, magic links, and OAuth providers like GitHub and Googleâusing the modular, composable auth hooks. Plug in Stripe or Lemon Squeezy in minutes via pre-built webhooks, subscription lifecycle handlers, and customer portal integrations. Activate the admin dashboard with one-line configuration for Plausible or Google Analytics, then extend it with custom widgets, role-based access controls, or export-ready reports. Its clean separation of concerns means adding new featuresâlike AI-enhanced content generation, file uploads to S3/Cloudflare R2, or transactional email via Resend or SendGridârequires minimal boilerplate and zero architectural trade-offs.
Deepen your mastery with interactive, LLM-augmented documentation that walks through advanced patterns: multi-tenancy scaffolding, webhook signature verification, rate limiting with Redis, or embedding the Astro-powered blog as a headless CMS. Deployment is streamlined with optional Wasp CLI toolingâbut entirely optional. Whether you prefer Git-triggered CI/CD pipelines or manual infra-as-code provisioning, Open SaaS adapts. And when questions arise, the vibrant Discord communityâcomprised of founders, senior engineers, and open-source maintainersâoffers real-time guidance, code reviews, and production war stories.
