Did development leftovers ship to production?
Signs of development settings in your live site: a development server, a development build of React or Vue, debug tools left switched on, or addresses that point at localhost.
Why it matters
Development builds are slower and often more talkative, and debug tools can reveal how your app works inside. Addresses pointing at localhost usually mean something is broken for real users. They are simple to fix once you know.
How a survey checks it
Passive check: part of every free survey.
We look for well-known development markers in your homepage and its scripts. Logging that might print tokens is reported for information.
How to fix it
- Build with your tool's production mode before deploying, and deploy the build output, not the development server.
- Replace localhost addresses with environment settings that point at your live services.
- Turn off framework debug and devtools options for production.

Common questions
How does this happen with AI-built apps?
Often an app is published while it still has settings from the preview environment, or a configuration value was never changed from its local default.
Is this serious?
Usually low on its own, but worth fixing before launch because it can hide other problems and slow your app down.
