🚀

Production-Ready in Minutes

Clone, configure env vars, deploy. Skip 2–4 weeks of SaaS boilerplate. Start from business logic on day one.

🧩

Modular Registry

Install features with `npx shadcn@latest add @saas/`. Each module declares its own routes, server actions, DB tables, and env vars.

🤖

AI Agent Team

12 specialized Claude Code agents — spec writer, reviewer, QA, evaluator, deployer, and more — automating the full epic → commit pipeline.

🔐

Auth + 3-Tier RBAC

NextAuth v5 (JWT) with viewer / editor / admin roles enforced at the server-action level. No custom auth code needed.

💳

Billing Abstraction

PaymentProvider interface with Stripe + ECPay adapters. Swap providers with one env var — no business logic changes.
