Open SaaS

Starting a SaaS product from an empty folder means rebuilding the same login, billing and admin screens every time.

Open SaaS is a free, open-source SaaS boilerplate that gives you those pieces already wired together, built on React, NodeJS and Prisma with full-stack type safety in TypeScript.

Out of the box you get authentication, Stripe or Lemon Squeezy payments, and an admin dashboard with analytics through Plausible or Google Analytics.

Open SaaS also includes an OpenAI integration, AWS S3 file uploads, email sending and an Astro-based blog.

That covers most of what a first paying customer expects to see.

The template stresses no vendor lock-in, so you can deploy it wherever you like.

It ships with documentation, end-to-end tests and community support.

The stack is fixed, so it suits you best if you are happy with React and Node.

If not, you will spend time swapping parts out instead of saving it.
