SaasSeed: Ship your SaaS 10x faster with Next.js + NestJS

Hey PH! 👋 I'm Baptiste, and I built SaasSeed because every time I started a new SaaS project, I spent weeks rebuilding the same things — auth, billing, teams, emails, admin panel... So I built the starter kit I wish I had: 🔐 Auth — JWT + OAuth (Google, GitHub) + email verification + password reset 💰 Stripe Billing — Subscriptions, plan management, upgrade/downgrade 👥 Teams — Multi-tenant organizations with role-based access 📧 Emails — Transactional emails with React Email (welcome, invoice, reset) 🔧 Admin — Complete dashboard with user & org management 🧪 500+ tests — Unit, integration & e2e across the full stack The stack is Next.js 16 + NestJS + Prisma + PostgreSQL — fully typed TypeScript from frontend to backend. No Supabase, no Firebase — you own and control your entire backend. It's a one-time purchase (€149) — no subscription, no recurring fees. You get the full source code and build whatever you want with it. Happy to answer any questions! 🙌
