Universal SaaS Builder Skill — Build Faster. Launch Free

Universal SaaS Builder is a free, open-source foundation that helps developers turn ideas into independent SaaS applications faster. It combines reusable TypeScript modules with a Codex skill, giving you a starting point for your product.

Describe what you want to build, then use the skill to plan your application, select modules and customize the foundation. Start with CRM, learning platform or helpdesk blueprints, or define custom entities for your own use case.

The foundation includes authentication, organizations, roles and permissions, content management, media storage, notifications, workflows, APIs and webhooks. Optional billing and AI integrations let you extend your application as your needs grow. Generated projects include typed database models, migrations, tenant-scoped APIs, forms and tests.

Every generated application has its own source code, configuration and deployment lifecycle. You retain control over how it evolves, where it runs and which services it uses.

Universal SaaS Builder is released under the MIT license, allowing personal and commercial use, modification and redistribution. All builder modules are included, with no purchase, license key, seat limit or activation requirement.

Generated applications still need product-specific business rules, configuration and testing before launch. Optional hosting, AI, email, payment and storage providers—and Codex usage—may have separate costs.

Start with the foundation. Make it your own. Build your business.

Building a SaaS often means repeatedly setting up authentication, team permissions, billing, databases and other shared features before working on the product itself.

Universal SaaS Builder reduces that repetitive work with a free, reusable foundation and Codex skill, helping developers focus on their product’s unique features and reach launch sooner.
