About this check

What the tool checks

View the server-delivered source without executing it. Binary files, unsupported content types and oversized responses are rejected.

How this check works

A secure fetch retrieves a bounded public HTML response and displays it as escaped text.

What this check cannot establish on its own

JavaScript-rendered DOM, authenticated content and resources outside the main document are not included.

Data sources

The final HTTP response body and headers returned at the time of the request.
