# What the outside of the app reveals

Anyone can see this from a browser. It is listed so you know what is on show.

## Why AI-built apps get this

Builders leave traces: a header, a build artefact, a familiar path, a meta tag nobody removed. On its own a fingerprint is harmless. It becomes useful to someone else when a class of issue is reported against a particular builder and they want a list of apps to try it on.

## Evidence line

x-powered-by: Express, build artefact names the framework

## The fix

Nothing to do unless something here is a surprise to you.

## Prompt

Review what the public pages reveal about the tools behind the app.
