FoundrySaaS: AI‑Ready Next.js + Supabase + n8n Starter Kit

**Launch your SaaS MVP in hours, not weeks.**

If you’re a solo founder, you know the pain of spending days wiring up authentication, billing, and automations before you even touch your core product. You waste precious time juggling Supabase, Stripe, and OpenAI integrations instead of building features that matter. That initial setup stretches out your launch timeline and drains your focus.

FoundrySaaS is an AI-ready starter kit built with Next.js, Supabase, and n8n that cuts through this setup overhead. It delivers 80% of your SaaS boilerplate out of the box, automates onboarding flows, email notifications, and error alerts, and provides deploy-ready files so you can skip weeks of backend grunt work. Unlike generic templates, this kit is optimized for rapid MVPs that integrate directly with Stripe billing and OpenAI APIs, saving you 12+ hours on backend setup and 6–8 hours on key integrations.

**What’s Included:**

- `auth.ts` — Complete user authentication with Supabase
- `billing.ts` — Stripe billing and subscription management
- `onboarding.workflow` — n8n automation for user onboarding emails
- `error_alerts.workflow` — n8n workflow for real-time error notifications
- `openai_integration.ts` — Prewired API calls for OpenAI features
- `deploy.sh` — One-command deployment script to Vercel or your server

**Who This Is For:**
- Solo founders launching an MVP with limited backend experience
- Developers who want to save hours wiring auth, billing, and automations
- Teams building AI-powered SaaS apps that need a quick, reliable foundation

**Who This Is NOT For:**
- Builders looking for a no-code drag-and-drop solution
- Projects that don’t require billing or user authentication

**Guarantee:**
If FoundrySaaS doesn’t save you at least 10 hours of backend setup time, I’ll refund your purchase—no questions asked.
