Open Saas

Open SaaS is a free, open source starter kit for building and launching a software as a service product, built on React, Node.js and Prisma and powered by the Wasp framework. It is aimed at developers and small teams who want the standard parts of a SaaS already wired together, with a particular emphasis on apps that include AI features. The template ships with full stack authentication that the builder owns, payment integration with checkout and webhooks for Stripe, Polar.sh and Lemon Squeezy, and an admin dashboard with analytics through Plausible or Google. It also includes an example AI powered app that calls the OpenAI API, file uploads using AWS S3 presigned URLs, built in email sending that pairs with cron jobs, and an Astro based blog written in Markdown. TypeScript types are generated across the whole stack, end to end tests run with Playwright, and a GitHub Actions pipeline is included. The project also provides custom agent rules, skills and tools intended for use with AI assisted coding tools, plus a free interactive course on building a SaaS. Because the builder owns all the code, the app can be deployed anywhere, either manually or with a single Wasp command. A hosted demo app lets visitors try the result first, and documentation and a Discord community provide support. The kit itself is free and 100 percent open source. The pricing page on the site belongs to the demo app and shows sample Hobby ($9.99 per month), Pro ($19.99 per month) and a 10 credit pack ($9.99) that builders replace with their own product IDs.
