After spending 10 years building SaaS applications, I got tired of writing the same authentication flows, payment integrations, and multi-tenant architectures over and over. Every new project meant weeks of setup before I could even start on the features that actually mattered.
I built FastSaaS because I was frustrated watching talented developers waste months on infrastructure instead of building products that solve real problems. Your time is valuable. You should spend it creating features your users will love, not debugging Stripe webhooks for the fifth time.
In the AI era, this matters even more. With tools like Claude and Cursor, you can ship features faster than ever, but only if your codebase has a solid foundation. FastSaaS gives AI assistants the clean, well-structured code they need to help you build incredible products.
Yes! You can explore the template on our GitHub repository. The preview showcases the structure and list all of the files of the repository. Also, the Makefile is present to provide you with a good idea of the developer environment and experience.
You get the full source code with no vendor lock-in. FastSaaS is built with clean, modular architecture that makes it easy to add, remove, or modify any feature. It's a starting point, not a cage. Thousands of developers have adapted it to everything from AI tools to vertical SaaS platforms.
All plans include comprehensive documentation and a 15-minute support call. Plus, the codebase is clean and well-documented, making it easy to work with AI coding assistants like Claude or Cursor when you need help.
Free templates are either incomplete, unmaintained, or lack critical features like payments and multi-tenancy. FastSaaS is production-ready from day one with everything you need to launch. Think of it this way: paying 79€ to save 50+ hours of development time means you're valuing your time at less than €2/hour if you build it yourself.
The Lifetime plan includes all future updates and improvements. Even with other plans, you own the code forever and can maintain it yourself. FastSaaS uses stable, widely-adopted technologies (FastAPI, PostgreSQL, Stripe) that won't disappear overnight. We're actively maintaining and improving the template based on real customer feedback.
FastSaaS is production-ready from day one. You get a complete, battle-tested FastAPI codebase with working user authentication, Stripe payments, multi-tenant teams, email workflows, error monitoring, and CI/CD pipelines. Companies are running their businesses on FastSaaS right now.
Yes! The Premium plan includes a license for 1 commercial project. The Infinite and Lifetime plans include unlimited commercial projects.
