Open Source

Open SaaS is a fully open-source, free SaaS starter built on Wasp, a full-stack React, Node.js, and Prisma framework whose client is built with Vite. It comes with pre-configured auth, checkout and webhooks for Stripe, Paddle, Polar.sh, or Lemon Squeezy, an admin dashboard with Plausible or Google Analytics, an OpenAI example app, S3 file uploads, email via SendGrid, Mailgun or SMTP, and an Astro-based blog and docs. Wasp adds end-to-end type safety, background jobs, and one-command deploys to Railway or Fly.io, and the repo ships agent rules and skills for AI coding tools.

Full-stack type safety and cron jobs via Wasp with no extra config
