AI Boilerplate is the Next.js SaaS boilerplate built for vibe coding with Claude and Cursor. It ships with everything you'd otherwise spend 160+ hours wiring yourself: authentication (email, magic links, Google, GitHub), Stripe subscriptions and a credits system, a full user dashboard, file storage on Cloudflare R2, transactional email via Resend, MDX blog, Fumadocs documentation, feature flags, theming, and a typed tRPC + Prisma backend that runs on Supabase Postgres or MongoDB.

What makes it different from other starters: AI coding tools generate code fast, then rot it. By prompt 50 it's spaghetti. AI Boilerplate is engineered to survive that. Built-in Claude and Cursor rules hand the AI your conventions before it writes a line, a modular monorepo keeps one change from breaking unrelated features, production patterns keep it safe by default. You own the full source code on day one. One-time payment, lifetime updates, and a private founder Discord where we help you ship.
