The AI-Native Next.js Starter Kit 🤖

Engineered for modern development. Optimized for AI.

This is the Open Source / Lite Version of Indie Kit Pro. It combines a production-grade tech stack with "AI Context Rules" that empower LLMs (Cursor, Windsurf, Copilot) to understand your codebase, write bug-free code, and navigate your project autonomously.

🚀 Features

Core Stack - The Right Architecture

• 🏗️ Next.js 16 (App Router) - Staying ahead of the curve.
• 🎨 Tailwind CSS v4 + Shadcn UI - Beautiful, accessible UI.
• 🔐 Better Auth (Social + Magic Link) - Secure and simple.
• 🗄️ Drizzle ORM + Bring Your Own Database - Connect to Supabase, Neon, or any Postgres provider.
• 💳 Stripe Subscription Webhooks - Ready for monetization.
• 📁 UploadThing for file storage - Easy file uploads.
• 🌙 Dark Mode built-in - Because developers love it.

Pre-built Pages

• 🏠 Landing Page (Hero, Features, Pricing, FAQ)
• 🔐 Auth Pages (Sign In, Sign Up)
• ⚙️ App Layout (Header, User Profile)
• 📄 Legal Pages (Privacy, Terms)

🤖 AI-Optimized Architecture

We've structured the codebase to be easily understood by LLMs (Cursor, Windsurf, Copilot, Antigravity). This means fewer hallucinations and better code generation, regardless of which tool you use.

• Self-Documenting Code: Your AI knows exactly where auth lives (.claude/skills/auth-handler), how to migrate the DB (.cursor/rules), and where to put new components.
• No Hallucinations: We force the AI to use existing patterns (like withAuthRequired) instead of inventing broken ones.
• One-Shot Prompts: Paste a single command like /bootstrap and watch it scaffold your entire MVP plan.

💡 Pro Tip: To use this kit with Google's Antigravity or other AI agents that expect a .agent folder, simply rename .claude to .agent:

mv .claude .agent

🛠️ Getting Started

⚡️ Quick Start (Recommended)

Run the following command to scaffold a new project interactively:

npx indiekit@latest 
# or
pnpm dlx indiekit@latest
# or
yarn dlx indiekit@latest

This CLI will:

• 🚀 Scaffold the project instantly (no git history to remove).
• 🛠️ Guide you through setup options.
• 📦 Install dependencies automatically.

🐢 Manual Setup

If you prefer to clone the repo manually:

1. Clone & Install

git clone https://github.com/Indie-Kit/nextjs-saas-starter.git my-saas
cd my-saas
pnpm install

2. Environment Setup

Copy the example environment file and fill in your secrets:

cp .env.example .env

You will need:

• Database URL: Use Supabase, NeonDB, or any PostgreSQL provider.
• Better Auth Secret: Run npx auth secret to generate.
• Stripe Keys: For payment processing.
• Social Keys: (Google/GitHub, optional).

Also, update src/lib/config.ts with your project name, description, and legal details (email, address) which are used in the footer and legal pages.

3. Database Setup

# Sync database schema to the database after adding new tables or modifying existing tables
pnpm run db:push

4. Run Development Server

pnpm dev

Open http://localhost:3000 to see your app.

🧠 The AI "Brain" (Exclusive)

This kit is designed to be "read" by LLMs. It includes:

• .cursor/rules: Context-aware rules for Cursor to understand project structure.
• Prompt Library: Pre-written prompts to generate features, DB schemas, and tests.
• Self-Correction: Setup to help AI fix its own linting errors.
• Skills: Specialized instructions for the AI to handle Auth, DB, and Payments correctly.
