Open SaaS is a robust, 100% free, and open-source boilerplate designed for rapidly building modern SaaS applications. Leveraging the powerful Wasp full-stack framework, it integrates React, Node.js, and Prisma to provide a comprehensive development foundation. The project comes packed with essential features out-of-the-box, including full-stack authentication with multiple providers, integrated payment solutions (Stripe, Polar.sh, Lemon Squeezy), email sending capabilities, background job processing, and S3 file uploads. Furthermore, its AI-ready architecture, complete with custom plugins and skills, alongside a streamlined one-command deployment process, significantly accelerates development. This allows creators to focus on core product innovation and unique business logic, rather than spending time on repetitive boilerplate setup.
