Overview

Open SaaS is a free, MIT-licensed SaaS boilerplate from the team behind Wasp, the full-stack React, Node.js and Prisma framework. Running wasp new -t saas scaffolds a complete app with authentication, payments, an admin dashboard, a landing page, background jobs and file uploads, with shadcn/ui for components and styling.

Because it is built on Wasp, much of the plumbing comes from the framework: full-stack auth in a few lines, end-to-end type safety between server and client, cron jobs and queues defined in config, and one-command deploys to Railway or Fly.io. It also ships an Astro Starlight site for docs and a blog, plus AI coding rules and plugins for tools like Claude Code and Cursor.
