Production-ready SaaS foundation

Ship your SaaS in days, not months.

Starterbase is a production-ready FastAPI and Next.js template for founders who want to build the product instead of rebuilding authentication, billing, organizations, admin panels, and deployment plumbing. It gives a new SaaS project a maintained technical foundation from the first commit.

Use Starterbase to launch a real application with typed APIs, role-based access, payments, background jobs, and a modern frontend already wired together. Keep the parts that differentiate your product, then start from a foundation designed to handle the ordinary work that usually slows a SaaS launch down.

It is built for developers shipping subscription products, B2B software, and internal tools who need a practical starting point rather than another demo repository. Clear backend and frontend boundaries make the template easier to extend, deploy, and maintain as the product grows.
