Org-first. AI-ready. Better Auth, Prisma and Stripe on Next.js 16 or TanStack Start-wired, tested, and running on Cloudflare, Vercel or Docker the day you clone it.
I build the boring infrastructure so you don't have to.
Every multi-tenant B2B SaaS needs the same two weeks of work up front: organizations, invites, roles, 2FA, Stripe seats, transactional email, file uploads, a deploy pipeline. None of it is your product. All of it is required before your product can exist.
SaaS Prokit is that two weeks, already done-org-first from the first migration, not bolted on later.
Give indie developers and small teams the boring infrastructure, so the two weeks you would spend wiring auth and billing go into the one feature only you can build.

- 🔐 Authentication & 2FA-Better Auth, sessions, password reset, TOTP
- 🏢 Organizations-multi-tenant from the schema up, invites, member management
- 🛡️ Role-based access control-permissions enforced server-side, not just hidden in the UI
- 💳 Billing-Stripe subscriptions, seats, webhooks, customer portal
- 📧 Email-transactional templates via Resend
- 📁 File uploads-validated, scoped to the org that owns them
- 🚀 Deployment-three targets, pre-configured, no "works on my machine"
The kit ships with 11 Claude Code skills so your AI agent works from the codebase's own conventions instead of guessing at them.

Would rather it were already built? I also take on MVP builds-get in touch.
Things I've built in public along the way:
- turborepo-nextjs-prisma-postgres-a full forum: NestJS, Prisma, Auth.js, Postgres, shadcn/ui, Tailwind
- nestjs-hexagon-onion-ddd-boilerplate-production NestJS with DDD, hexagonal/onion layering, CQRS
- strapi-press-headless blog on Strapi + Next.js + Turborepo
- coding-rules-the conventions I hold TypeScript, React, Next.js and NestJS code to
- react-collection-shadcn, Zod, Yup, uploads and other patterns, isolated
Building something multi-tenant and stuck on the org model? I answer questions in Discord-no purchase needed.
