How to Deploy a Vibe-Coded App From Localhost to a Domain

A beginner-friendly deployment path for AI-built apps that work locally but are not live on a real domain yet.

The short version

If your app works on localhost, you already have the hardest emotional part done: you made something real enough to test. Shipping means moving that project from your laptop into a production environment, connecting it to a domain, protecting secrets, and making sure it keeps running after you close your computer.

This guide is for builders using Claude, Gemini, Cursor, Lovable, Bolt, Replit, or plain local code who are stuck at the exact point where tutorials start assuming you know infrastructure.

  • Choose the right hosting target for your app.
  • Prepare environment variables and production build commands.
  • Deploy the frontend, backend, database, and background jobs.
  • Point the domain and add HTTPS.
  • Run a final production checklist before sharing the URL.

When to use this path

Use this path when your project has more than a static frontend. If you have an API, authentication, database, file uploads, email sending, background workers, cron jobs, or AI calls that need secure API keys, you need a production setup instead of just copying files somewhere.

  • Good fit: React plus Node API, Python/FastAPI, Postgres, Stripe, OpenAI/Anthropic calls, email sending.
  • Not a fit: a simple landing page that can be deployed to Vercel, Netlify, or Cloudflare Pages in minutes.

A beginner deployment flow

Start by writing down what your app actually needs. Most deployment problems happen because people deploy the frontend and forget the API, database, worker, secrets, or email service.

Then create a production checklist before touching a server. The checklist should include build command, start command, required environment variables, database URL, domain, SSL, logs, and backup plan.

# Example checks before deployment
npm run build
npm run lint
printenv | grep DATABASE_URL
curl https://your-domain.com/health

Common mistakes

The most common mistake is thinking deployment is one step. Real deployment is a chain. If one link is missing, the app appears broken even if the code is fine.

  • Using localhost URLs inside production code.
  • Committing API keys instead of using server-side environment variables.
  • Moving the app without moving the database schema.
  • Forgetting to configure email DNS records.
  • No logs, so failures become guesswork.

Short checklist

  • Frontend loads from a real domain.
  • API is reachable over HTTPS.
  • Database is production-ready and backed up.
  • Secrets are stored outside the codebase.
  • Email sending and DNS records are configured.
  • A restart or server reboot does not kill the app.
