TurboStarter vs Yellow Systems

Unified Multi-Platform Codebase

Build for web, mobile, and browser extension simultaneously from a single, shared codebase. TurboStarter leverages modern tools like Next.js for the web, Expo for native mobile apps, and WXT for Chrome extensions, all orchestrated within a Turborepo monorepo. This eliminates the nightmare of managing three separate codebases, ensuring consistency, streamlining development, and allowing you to deploy a complete product ecosystem in a fraction of the traditional time.

Pre-Built Core SaaS Functionalities

Hit the ground running with essential, production-grade features already integrated and configured. TurboStarter comes with comprehensive authentication flows (email/password, social logins, 2FA), subscription and one-time payment handling through Stripe and Lemon Squeezy, multi-tenant organization/team management with RBAC, and a full admin dashboard. This removes hundreds of hours of complex, error-prone integration work, letting you focus purely on your unique business logic.

One-Click Deployment & DevOps

Deploy your entire suite of applications—web, mobile, and extension—with a single command. TurboStarter abstracts away the complexity of cloud infrastructure, CI/CD pipelines, and app store submissions. This feature ensures that from your local development environment to a live, user-accessible product is a seamless, automated process, enabling truly rapid deployment and instant iteration.
