AI-Built Sites: What Breaks After Publish

28 May 2026 · 2 min read · Part of: AI to Production · Step 1

You shipped with v0, Cursor, Bolt, or a no-code builder. Preview looked great. Then production broke. That gap is normal, and fixable.

Why preview and production are different

AI tools and no-code platforms run your site on their stack first. Going live means domain, DNS, SSL, environment variables, form endpoints, and error monitoring. Most breakages sit in that handoff, not in the design.

What usually breaks first

  • Contact forms submit but email never arrives
  • API keys still point at localhost or test mode
  • Mobile layout breaks outside the builder preview
  • Site feels slow once real traffic and plugins load
  • Deploy works once, then breaks on the next push

What to do before you rebuild

List what is broken, check DNS and SSL, confirm form endpoints and env vars in production, then decide: patch, takeover, or rebuild. Skip buying more plugins until you know the root cause.

Common questions

Is it normal for AI-built sites to break after publish?

Yes. Builders optimize for fast previews. Production needs hosting, DNS, keys, and monitoring that AI output often skips.

Should I rebuild or fix?

Fix if the structure is sound and only config is wrong. Rebuild or takeover if the stack is unmaintainable or you cannot access hosting.

step 1

How did you build it?

Tap one.

step 2

What's broken?

Tap all that apply.

step 3

Preview vs live reality

---
Preview runs on the builder stack and hides environment gaps.
--
Production needs DNS, SSL, env vars, API keys, and real form endpoints.
--
If it worked in preview but failed live, the gap is deployment plumbing.

step 4

Checklist most builds skip

- Form endpoint points to localhost or placeholder URL
- API keys missing from production environment
- DNS and SSL not fully propagated
- Add monitoring before the next launch
