Open Saas provides a full-stack React and Node.js framework for building SaaS applications.
Some key features:
It is open-source and free to use, with no vendor lock-in so the application can be deployed anywhere.
Common SaaS features are pre-built and configured, such as authentication, payments integration via Stripe, email sending, file uploads, and an admin dashboard.
Rapid development is supported through Wasp1, a compiler that generates code for the frontend, backend, and deployment. This allows a MVP to be built in a short period, like the examples cited of 3 days or 6 nights of work.
In summary, this template aims to provide a full-featured starting point for SaaS apps that can be set up and customised quickly at no cost through its open-source nature and pre-integrated common features.
