Open SaaS Introduction

Open SaaS Introduction. Open SaaS: Free React + Node.js + Prisma boilerplate with auth, payments, AI & admin dashboard—launch your SaaS in minutes! 🚀

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 foundation—pre-wired with secure authentication, battle-tested payment flows, intelligent AI extensions, and a feature-rich admin interface. This isn’t just scaffolding: it’s a cohesive architecture where TypeScript enforces end-to-end type safety, database migrations are versioned and reversible, and every layer—from frontend routing to backend billing logic—is designed for real-world SaaS requirements. With zero proprietary abstractions and no hidden dependencies, Open SaaS puts you in full control—deployable on Vercel, Railway, AWS, or your own Kubernetes cluster—without 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 flow—supporting email/password, magic links, and OAuth providers like GitHub and Google—using 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 features—like AI-enhanced content generation, file uploads to S3/Cloudflare R2, or transactional email via Resend or SendGrid—requires 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 tooling—but 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 community—comprised of founders, senior engineers, and open-source maintainers—offers real-time guidance, code reviews, and production war stories.
