Frequently Asked Questions

Is this just a Next.js template or a full-stack solution?

VibeFast is a complete full-stack solution. You get a production-ready Next.js web app with a Convex or Supabase backend, authentication, payments, and AI features. It's not a UI library—it's a working SaaS that you customize for your product.

Can I use this without the mobile app?

Yes! While VibeFast includes both web and mobile apps, they're modular. You can ship just the Next.js web app if that's all you need. Many customers start with web and add the mobile app later.

What payment processor does it use?

The web app uses Stripe for payments (Lemon Squeezy is also supported). You can accept one-time payments, subscriptions, and manage customer billing. Webhook handlers and subscription checks are included.

How does authentication work on the web?

VibeFast supports both Convex Auth and Supabase Auth with Google, GitHub, and email/password login. Sessions are managed server-side with secure cookies. Protected routes and middleware are already configured.

Is it optimized for SEO?

Absolutely. The web app includes proper metadata handling, automatic sitemap generation, robots.txt, structured data (JSON-LD), Open Graph tags, and optimized Core Web Vitals. The blog and docs are server-rendered for maximum SEO.

Can I deploy this on Vercel?

Yes, VibeFast is optimized for Vercel deployment. Next.js runs on Vercel's edge network, and the backend deploys separately. The documentation includes step-by-step deployment guides for both.
