StarterApp Official 1.0 Release
After months of development and refinement, StarterApp 1.0 is here. A production-ready SaaS starter built for AI-assisted development with complete auth, billing, and security.
StarterApp 1.0 is officially here. After months of development, we're releasing a SaaS starter built specifically for AI-assisted development. Production-grade infrastructure ready to use.
We built StarterApp because we kept rebuilding the same pieces for every SaaS project. Authentication flows, billing integrations, security configurations, testing harnesses. Each time, weeks of setup before writing actual product code. There had to be a better approach.
What Problem This Solves
StarterApp addresses the cold start problem. Instead of scaffolding auth and billing from scratch, you get implementations that handle edge cases, security concerns, and production requirements from day one.
More importantly, it's built to work with AI. Every component, pattern, and integration is documented and structured so AI coding assistants understand your architecture and generate code that fits. You stop fighting with AI-generated code that breaks your patterns or security model.
What's Inside StarterApp 1.0
Here's what you get out of the box:
Production-Ready Authentication
Complete auth system powered by BetterAuth with OAuth providers, email verification, password reset flows, and session management. Security best practices are built in: CSRF protection, secure session handling, and rate limiting on auth endpoints.
- Multiple OAuth providers (Google, GitHub, and more)
- Email/password authentication with secure hashing
- Magic link authentication for passwordless flows
- Session management with automatic refresh
- Protected routes and middleware for server-side auth checks
The auth system integrates seamlessly with Convex, so you get realtime database access with proper authentication out of the box.
Stripe Billing Integration
Billing is hard to get right. StarterApp includes a complete Stripe integration powered by UseAutumn that handles subscriptions, one-time payments, usage-based billing, and customer portals. The integration is type-safe and handles webhooks correctly.
- Multiple pricing tiers with feature gating
- Subscription management with automatic renewal
- Customer billing portal for self-service
- Usage-based billing for metered features
- Webhook handling with proper error recovery
- Type-safe billing queries and mutations
Feature gating is built into the system, so you can check a user's plan and entitlements anywhere in your app with a simple helper function.
Modern, Production-Tested Stack
StarterApp uses the latest production-ready technologies:
- Next.js 15 with App Router, React Server Components, and Server Actions
- React 19 with improved hydration and streaming
- TypeScript with strict mode and comprehensive type safety
- Convex for realtime database with serverless functions
- Tailwind CSS with shadcn/ui component library
- Turborepo monorepo with shared packages
Everything is configured to work together. No version conflicts, no configuration headaches, no "it works on my machine" problems.
Security From Day One
Security is built into StarterApp from the start. Every endpoint has CSRF protection. Every mutation is rate-limited. Content Security Policy headers are configured correctly. Session handling follows best practices.
- Comprehensive Content Security Policy (CSP) configuration
- CSRF protection on all mutations and form submissions
- Rate limiting on auth and API endpoints
- Secure session management with HTTP-only cookies
- Environment variable validation with build-time checks
- Security headers configured in middleware
The security package exports helpers that make it easy to maintain these protections as you build new features.
AI-Native Development Experience
What makes StarterApp different is how it's built for AI-assisted development. The codebase is context-engineered: structured and documented so AI models can understand your architecture and generate code that fits your patterns.
- Comprehensive documentation in plain language
- Consistent patterns and naming conventions
- AI workflow commands for common development tasks
- Templates for authentication, billing, and feature implementation
- Clear separation of concerns with typed boundaries
Works with Cursor, GitHub Copilot, Claude, and ChatGPT. The structure helps AI assistants understand what you're building and generate code that fits your existing patterns.
Testing Suite Ready to Go
StarterApp includes a complete testing infrastructure with unit tests, integration tests, and end-to-end tests configured and ready to use.
- Vitest for fast unit and integration testing
- React Testing Library for component tests
- Playwright for end-to-end testing with multiple browsers
- Test fixtures and helpers for common scenarios
- CI-ready configuration with parallel execution
Authentication flows, billing integration, and protected routes all have test coverage. You can build on these tests as you add features.
Documentation That Stays Current
StarterApp ships with complete documentation covering architecture, deployment, authentication patterns, billing integration, security requirements, and testing standards. Every pattern includes examples and every integration has guides.
The documentation lives alongside the code in the monorepo, so it stays current as the codebase evolves. Whether you're onboarding a team member or asking an AI to build a feature, the docs provide the context to understand how everything fits together.
What's Next
This 1.0 release is the foundation. We're already working on expanded AI workflow commands, additional authentication providers, more billing patterns, and deeper integrations with popular SaaS tools.
Every update maintains backward compatibility within major versions. Your lifetime license includes all future updates with no subscriptions or surprise charges.
