Greenfield Foundation
Build Right
Start on safe foundations.
Most AI-built SaaS apps start without trustworthy auth, production billing, or a safe admin layer. Then founders spend months patching what should have been there from day one. We install those foundations first — so you build features on stable architecture, not patches.
Foundation Modules
Three production-critical layers that AI tools get wrong by default — fixed from install.
Auth
Identity Layer
Server-side verified auth with HttpOnly cookies, RLS templates, and 22 lint rules. Register, login, logout, reset-password.

Money Layer
Stripe subscriptions with webhook inbox pattern, entitlement engine, dunning-safe access, and automatic reconciliation.
asa install payments-basicLearn more →Admin
Control Layer
RBAC with permission guards, immutable audit log, safe impersonation with reason + TTL, and user management.
asa install admin-basicLearn more →All modules generate standard Next.js + Supabase + Stripe code. No runtime dependency on ASA. db-basic is auto-installed as a shared dependency. View all Foundation Modules →
How it works
Discovery & architecture design
We review your requirements — what you're building, which features matter first, and your deployment target. We design the architecture before writing a single line of code.
We configure & install
We install three production layers configured for your specific app: auth (register, login, logout, reset-password), billing (subscriptions, webhooks, entitlements, reconciliation), and admin (roles, audit log, impersonation, user management). Database infrastructure is included underneath as an internal shared dependency.
Verification & handoff
Architecture is verified with asa verify. You receive a working repository with clean boundaries, typed access, and .cursorrules for Cursor. Ready to build features.
Who this is for
The stack
We build on the same stack used by thousands of production SaaS apps. No custom frameworks. No vendor lock-in. Standard, proven tools.
Next.js
App Router + TypeScript + React
Supabase
PostgreSQL + Auth + Realtime
Stripe
Payments + Subscriptions + Webhooks
Vercel
Deployment + Edge + CI/CD
Tailwind + shadcn/ui
Modern UI components
ASA boundaries
Architecture enforcement + .cursorrules
Supabase gives you the backend. Vercel gives you the runtime. ASA gives you the architecture.
What this is not
→ Not a template or boilerplate. Every project is configured for your specific requirements.
→ Not a framework dependency. The generated code is standard Next.js + Supabase + Stripe. No runtime dependency on ASA.
→ Not a full app build. We install the foundation — you build the features on top.
→ Not ongoing development. This is a one-time engagement. Optional managed support is available separately.
Pricing
Depends on scope: number of foundation modules, custom configuration, and deployment setup.
→ Typical: full production foundation (auth + billing + admin) = ~$1,500
→ Delivery: 2–5 days
→ Starts with a diagnostic to confirm scope and fit
Frequently asked questions
Can I continue building with Cursor or Windsurf?
Yes. The generated code is standard Next.js + Supabase + Stripe — it works in any IDE. The project includes .cursorrules that guide Cursor's AI to respect architectural boundaries. For Windsurf, equivalent rules can be configured. If you started in Lovable or Bolt, you'd export and continue in a local IDE.
What if I already have some code?
If you have an existing codebase that needs stabilization, our Stabilize service is a better fit. Build Right is designed for new projects or very early-stage apps.
Do I need the ASA CLI after setup?
The CLI is optional after initial setup. Your codebase is standard Next.js + Supabase + Stripe. The CLI can help you add slices and enforce boundaries as you grow, but it's not required.
What happens after the foundation is installed?
You get a working repository with three production foundations already installed: usable auth flows, production billing with Stripe, and a secure admin control surface. Then you build your product features on top. If you want ongoing architecture enforcement, we offer CLI licenses and managed support.
The path to stability
Four phases. Each is a separate engagement. You decide at each step whether to continue.
Diagnose
Architecture Audit
Structural failure patterns identified. AI Chaos Score. Prioritized roadmap.

Start building on architecture that scales.
Every SaaS app needs trustworthy auth, production billing, and a safe admin layer. The question is whether you build it right from the start — or patch it later at 10× the cost.
