TurboStarter

TurboStarter is a production-ready starter kit for launching SaaS products across web, mobile, and browser extension platforms from a single unified codebase.

What is TurboStarter?

TurboStarter is a comprehensive starter kit built by Bart Zagrodzki that accelerates the development and deployment of SaaS applications across web (Next.js), mobile (React Native / Expo), and browser extension (WXT / Vite) platforms. It takes a developer's idea or project requirements and produces a fully functional, deployable multi-platform app with built-in authentication, billing, internationalization, SEO, and more. The kit runs on any modern development environment (local or cloud) and is designed to work seamlessly with popular AI coding tools like Cursor, Claude Code, and GitHub Copilot. You can see a live demo at demo.turbostarter.dev and explore the documentation at turbostarter.dev/docs.

Key Features

• Multi-Platform Unified Codebase — Build for web (Next.js), mobile (Expo), and browser extension (WXT) simultaneously with shared packages for AI, auth, billing, database, email, and UI. See web, mobile, and extension docs.
• AI-Ready Development — Includes dedicated rules, skills, agents, and commands for Cursor, Claude Code, Codex, Windsurf, GitHub Copilot, Replit, and Zed to accelerate code generation and refactoring. Learn more about AI development.
• Built-In Authentication — Supports email/password, magic link, OTP, passkeys, social login (Apple, Google, GitHub), and two-factor authentication out of the box.
• Multi-Provider Billing — Integrates with Stripe, Lemon Squeezy, Polar, Dodo Payments, RevenueCat, and Superwall for one-time or recurring payments.
• One-Click Deployment — Deploy all apps (web, mobile, extension) with a single command, handling format, lint, test, and publish steps automatically.
• Internationalization (i18n) — Full multi-language support for web, mobile, and extension with built-in translation infrastructure.
• Organizations and Teams — B2B-ready multi-tenancy with roles, permissions, and RBAC for managing users and teams.
• 25+ Ready-to-Launch SaaS Ideas — Curated business ideas across all platforms to help founders get started quickly. Browse SaaS ideas.
• CLI and MCP Support — A command-line interface and built-in Model Context Protocol for common tasks like project setup and provider configuration.

Who is it for?

• Startup founders who want to launch a multi-platform MVP in days rather than weeks, without rebuilding common SaaS infrastructure.
• Indie hackers and solopreneurs who need a complete, production-ready codebase to validate and monetize their product ideas across web, mobile, and browser extensions.
• Experienced developers who want to skip boilerplate setup (auth, billing, admin, SEO) and focus immediately on custom features and business logic.
• Agency teams building multiple SaaS products for clients, benefiting from a standardized, reusable starter with lifetime updates.

What can you do with TurboStarter?

• Launch a subscription-based SaaS app — Set up recurring billing via Stripe or Lemon Squeezy, manage users with authentication and teams, and deploy to web, mobile, and extension simultaneously.
• Build an AI-powered product — Use the included AI Kit (part of the Bundle) to integrate multiple AI providers, tool calling, memory, rate limiting, and credit-based access for web and mobile.
• Create a bilingual productivity tool — Leverage built-in i18n for multi-language support, add a browser extension companion, and monetize with one-time or subscription payments.
• Ship a content marketplace — Use the 25+ SaaS ideas (e.g., SyncReads, Socialcrawl) as a starting point, customize the landing page, SEO tags, and email templates provided in the kit.

How does TurboStarter work?

1. Clone or use the CLI to generate a new project with your chosen providers (e.g., Stripe for billing, Supabase for database).
2. Configure environment variables for your integrations (database, auth, email, etc.).
3. Customize the apps: modify the web app (Next.js), mobile app (Expo), or extension (WXT) codebases independently or add shared features.
4. Run one-click deploy to publish all apps to their respective stores and hosting platforms.
5. Iterate with AI-assisted tools that follow the project's AGENTS.md and CLAUDE.md rules for consistent code generation. See AI development for details.
