TurboStarter FAQ
What is the main advantage of using a monorepo with TurboStarter?
The primary advantage is unparalleled development efficiency and consistency for multi-platform products. A monorepo allows you to manage shared code—like authentication logic, data models, UI components, and API types—in one place, automatically synced across your web app, mobile app, and browser extension. This eliminates the "integration phase" nightmare, reduces bugs from platform divergence, and allows a single feature to be developed and released across all platforms simultaneously, managed by Turborepo's optimized build and task orchestration.
How does the "15-minute to production" claim work?
This is achieved through TurboStarter's comprehensive pre-configuration and automation. Using the provided CLI, you can generate a new project tailored to your chosen services (e.g., Stripe for payments). The kit includes all necessary infrastructure-as-code configurations and deployment scripts. With one command, you can deploy the backend (e.g., to Vercel, with a connected Supabase PostgreSQL database), the web frontend, and publish the initial builds. The 15-minute timeframe refers to having a live, publicly accessible production environment with core SaaS features running, not a fully customized product.
Can I customize the tech stack or replace specific integrations?
Yes, TurboStarter is designed as a robust foundation, not a locked-in framework. While it comes with opinionated, best-in-class defaults (like Better Auth for authentication or Drizzle for ORM), the codebase is entirely yours to modify. You can swap out Stripe for another payment processor, replace Tailwind CSS with another styling solution, or integrate additional databases. The monorepo structure and clear separation of concerns make such customizations straightforward for developers familiar with the underlying technologies.
Is TurboStarter suitable for non-SaaS applications?
While TurboStarter is explicitly optimized for SaaS products with its built-in billing, multi-tenancy, and subscription logic, its core architecture is highly beneficial for any complex application targeting web, mobile, and extension platforms. The authentication, project structure, deployment setup, and development tooling can provide a significant head start for other project types. However, you may need to remove or heavily modify the billing and organization modules if they are not required for your specific use case.
