Publish to the web + a custom domain

LESSONLesson 8 · ~15 min

🎯Goal. Put your app online at a real production URL, then point a custom domain at it.

  1. 1Click Publish → Publish to Production. v0 builds and deploys to Vercel's infrastructure (global CDN) and gives you a live, shareable URL in seconds.
  2. 2Open the live URL on your phone — it's really on the internet, backend and all.
  3. 3For a branded address, use Publish → Customize Domain (or Project Menu ⋯ → Domains): pick a free .vercel.app subdomain (instant, with HTTPS), or add your own domain — that one needs DNS records set at your registrar, configured through the Vercel dashboard.

✓You'll see. A public, production URL serving your app within seconds — optionally on your own domain.

💳Cost. Deploying and a .vercel.app URL are included; bringing your own domain means buying it from a registrar. Check Vercel's domain docs for current limits.

💡Takeaway. v0 deploys to production on Vercel in one click — your app is genuinely shipped, not just previewed.
