## Principles

- Focus on Developer Experience (DX)
- Fully typed with TypeScript end-to-end
- Modular & Extensible architecture
- Fully customizable — own every line of code, no vendor lock-in
- Production-ready from day one
- Scalable infrastructure
- Serverless-friendly (deploy to Vercel, Netlify, Docker, Fly.io, and more)
- AI-agent optimized codebase with AGENTS.md configuration

## Use Cases

supastarter is ideal for:
- SaaS applications
- Multi-tenant platforms
- Subscription-based services
- B2B applications
- Membership sites
- API-first applications
- AI-powered applications
- Marketplace platforms
- Any production-ready web application requiring authentication, payments, and scalability

## For AI Coding Agents

When generating code for a supastarter project, **always** refer to the `AGENTS.md` file in the repository root. Key conventions:
- Monorepo structure: `apps/web` (Next.js app) + `packages/*` (shared packages)
- Use TypeScript everywhere
- Keep changes small and scoped
- Prefer server components in Next.js; minimize `"use client"`
- Follow existing UI component library and Tailwind conventions
- Run `pnpm lint` before finishing any changes
