The FastAPI boilerplate with all you need to build your SaaS and make your first $ fast.
$ git clone fast-saas
Here's what you're up against when you start from zero:
Spend 6-8 weeks building authentication, payment systems, multi-tenancy, email workflows, and admin dashboards instead of your actual product features.
Every week spent on boilerplate code is a week you're not generating revenue. Your competitors are already in the market while you're still setting up user management.
Build it yourself and you own every bug, security vulnerability, and maintenance headache. One authentication flaw could compromise your entire business.
Get the foundation you need to launch fast and scale confidently
Start with battle-tested code that handles all the boring stuff. Run "make setup" and you're ready to build your unique features immediately.
With Stripe integration pre-configured, you can start accepting payments and generating revenue within your first week of development.
Secure authentication, tested payment flows, and production-ready infrastructure from day one. Sleep well knowing your foundation is solid.
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.
Save 100+ hours of boring setup. Get straight to building features your customers will pay for.
Perfect for your first SaaS project
For agencies and serial builders
Full package with future updates
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.
