LaunchKit
Next.js SaaS Boilerplate with Auth, Payments & Admin - Launch Faster!
What is LaunchKit? Complete Overview
LaunchKit is a production-ready Next.js boilerplate that eliminates the tedious setup work for SaaS startups. It comes pre-built with essential features like authentication (OAuth & magic links via Supabase), Stripe payments (subscriptions & one-time), admin dashboard, and SEO-ready marketing pages. Designed specifically for indie hackers and solo founders, LaunchKit saves 80+ hours of development time by providing all the infrastructure code you'd normally have to build from scratch. The AI-friendly codebase works seamlessly with tools like Claude, Codex, and GitHub Copilot, allowing even non-technical founders to extend functionality through natural language prompts. With built-in TypeScript, Tailwind CSS, and Vercel deployment, you can go from zero to launched SaaS in record time.

What Can LaunchKit Do? Key Features
Pre-built Authentication
LaunchKit includes fully implemented OAuth (Google) and passwordless magic link authentication powered by Supabase. The system implements row-level security out of the box, saving you weeks of development time on user management and session handling. All edge cases (email verification, password resets) are already handled with polished UI components.
Stripe Payments Integration
Complete Stripe integration handles both subscription and one-time payments with pre-built checkout flows. The admin panel lets you manage products, prices, and customer subscriptions without writing backend code. Includes a customer portal for self-service billing changes and automatic webhook handling for payment events.
Admin Dashboard
A production-grade admin interface provides tools to manage users, view analytics, handle subscriptions, and monitor business metrics. Built with clean, responsive components that adapt to your SaaS needs. Saves months of development time typically spent building internal tools.
SEO-Ready Marketing Site
Includes pre-built landing pages, pricing tables, and an MDX-based blog system optimized for search engines. The content management system allows non-technical users to update marketing copy without touching code. All pages feature fast-loading designs with proper metadata and schema markup.
AI-Assisted Development
The codebase is specifically structured for AI tools like Claude and GitHub Copilot to understand and extend. Comes with prompt templates that let you generate new features through natural language. Even non-developers can implement complex functionality by describing what they need to AI assistants.
