The problem: "Vibe coded an app but it's still stuck on localhost?"
Asked on X: post 1, post 2

How do I fix this?

  1. Put the code on GitHub

    Create a repo and push your project. Make sure .env and other secret files are in .gitignore first (see the leaked-keys fix).

  2. Know what kind of app you have

    Only HTML/JS, or a front-end framework with no server? It's static: use Vercel, Netlify or Cloudflare Pages. Does it have a server, database or Python back end? Use Railway, Render or Fly.io.

  3. Connect the repo to the host

    Sign in to the host with GitHub, import the repo and accept the detected build settings. Most hosts auto-detect Next.js, Vite, Astro and common Python setups.

  4. Add environment variables in the host's dashboard

    Copy each key from your local .env into the host's environment settings. The app will usually crash or show blank pages without them.

  5. Read the build log when it fails

    Paste the first red error from the deploy log into your coding agent and ask it to fix that error only. Redeploy happens automatically on the next push.

Which tools can do this for me?

Vercel

Best fit for Next.js and most front-end frameworks; connects to GitHub and deploys on every push.

Netlify

Static sites and front-end apps from a Git repo or drag-and-drop folder.

Cloudflare Pages

Static sites on Cloudflare's network; generous free tier.

Railway

Back-ends, databases and full-stack apps (Python, Node, etc.) from a repo.
