Open SaaS

Building a SaaS from scratch means spending weeks just setting up the same foundational features every single time — authentication, payments, analytics, email, and more. Open SaaS is a free, open-source full-stack boilerplate built on React, NodeJS, and Prisma that gives you all of that, pre-configured and ready to go. It comes with authentication, Stripe and Lemon Squeezy payment integrations, an admin dashboard with Plausible and Google Analytics support, built-in OpenAI integration for AI features, AWS S3 file uploads, email sending, an Astro-powered blog, and full TypeScript type safety throughout. No vendor lock-in, deploy anywhere, and a strong community behind it — so you can stop rebuilding the basics and start building the product that actually matters.
