Frequently asked questions

Everything you need to know before you start building.

What's included in LaunchKit?
Authentication with email and Google OAuth, Stripe billing with free and pro tiers, an AI-powered chat interface, a polished dashboard with usage analytics, and a fully responsive landing page. Everything is pre-wired and deployment-ready.
What tech stack does this use?
Next.js 16 with the App Router and React Server Components, Supabase for authentication and database, Stripe for payments, the Vercel AI SDK with Claude for the chat feature, TypeScript in strict mode, and Tailwind CSS v4 for styling.
Can I customize everything?
Absolutely. You own the source code — there's no vendor lock-in or proprietary framework. Swap out providers, restyle components, add features, or strip out what you don't need. It's your codebase to shape however you want.
How does the AI chat work?
The chat connects to Claude through the Vercel AI SDK. Messages stream in real-time, conversations are saved to your Supabase database, and per-user usage is tracked automatically. The free tier includes 100 messages per month with unlimited on Pro.
How is billing handled?
Stripe handles everything — checkout sessions, subscription management, and webhooks are all pre-configured. Users can upgrade, downgrade, or cancel through the Stripe Customer Portal. Free and Pro tiers work out of the box.
