Indie Kit

Indie Kit is a free and open-source Next.js 16 starter kit — the Lite version of Indie Kit Pro — that ships with AI context rules so coding assistants like Cursor, Windsurf, and Copilot can navigate and extend the codebase without hallucinating.

What is Indie Kit?

Indie Kit is an AI-native SaaS starter kit built on Next.js 16 App Router and TypeScript 5. It takes a database URL, auth secret, and payment keys as configuration inputs and produces a fully functional web application with a landing page, authentication, a user-facing app layout, and legal pages. The kit is maintained by CJ (cjsingg) and distributed under the MIT license for the open-source Starter version.

Key Features

• Next.js 16 App Router — The project uses the latest App Router conventions with TypeScript 5, keeping the codebase aligned with current Next.js features.
• Tailwind CSS v4 + Shadcn UI — Styling comes from Tailwind CSS v4 and Shadcn UI, and built-in dark mode is included.
• Better Auth — Authentication handles social login and magic links, with a secret generated via npx auth secret.
• Drizzle ORM with Bring Your Own Database — PostgreSQL schema management works with Supabase, Neon, or any Postgres provider; sync the schema with pnpm run db:push.
• Stripe subscription webhooks — Basic Stripe support is wired in for subscription monetization.
• UploadThing file storage — File uploads are handled through UploadThing integration.
• Pre-built pages — Includes a landing page with Hero, Features, Pricing, and FAQ sections; Sign In and Sign Up auth pages; an app layout with header and user profile; and Privacy and Terms legal pages.
• AI Context Rules — The repository includes .cursor/rules, .claude/skills, a prompt library, and self-correction setup so AI coding tools follow existing patterns like withAuthRequired.

Who is it for?

Indie hackers and solo founders who want to launch a SaaS MVP in minutes by scaffolding a production-grade Next.js application. Developers who rely on AI coding assistants benefit from the structured context rules that reduce code-generation errors. It also suits small teams that want a MIT-licensed foundation they can extend without starting from scratch.

What can you do with Indie Kit?

• Indie hackers: scaffold a new SaaS project by running npx indiekit@latest and connecting their own database, Stripe keys, and social auth providers.
• AI-assisted developers: use one-shot prompts like /bootstrap and the included skills to generate features, DB schemas, and tests with Cursor, Windsurf, or Copilot.
• Founders validating ideas: publish a landing page, sign-up flow, and Stripe subscription form using the pre-built pages, then iterate based on feedback.

How does Indie Kit work?

The recommended path is the interactive CLI: run npx indiekit@latest, answer setup questions, and dependencies are installed automatically. For manual setup, clone the repository, copy .env.example, fill in the database URL, Better Auth secret, and Stripe keys, update src/lib/config.ts, run pnpm run db:push, then pnpm dev to start at localhost:3000.

Indie Kit Pro vs Starter

The free Starter includes Next.js 16, Better Auth, Postgres and Drizzle, basic Stripe subscriptions, and basic AI navigation rules. The paid Indie Kit Pro adds Dodo Payments, Stripe Payments, Lemon Squeezy, PayPal, multi-tenancy with teams and organizations, role-based access control, user impersonation, a super admin dashboard, a credit system, waitlist system, blog and docs in MDX, email sequences with Inngest, and a documentation site.
